In an Android application, I want to display a custom list view in an AlertDialog. 

How can I do this?

How to set part of text to bold when using AlertDialog.setMessage() in Android?

I need to make a `AlertDialog` with a custom view.
The message of a `AlertDialog` has a default padding but when I set a view it has no padding, I want to get the same padding as the default as the message. I&#39;m using a style that extends Holo theme (if this is relevant).

    AlertDialog.Builder builder = new AlertDialog.Builder(PlaylistListView.this.getContext());
    builder.setTitle(&quot;Title&quot;);
    builder.setView(inflate(context, R.layout.music_player_create_dialog, null));
    builder.setPositiveButton(&quot;OK&quot;, null);
    builder.setNegativeButton(&quot;Cancel&quot;, null);
    builder.show();

This is the layout for the content:

    &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:orientation=&quot;vertical&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;
        android:paddingLeft=&quot;@dimen/abc_dialog_padding_material&quot;
        android:paddingRight=&quot;@dimen/abc_dialog_padding_material&quot;
        android:paddingTop=&quot;@dimen/abc_dialog_padding_top_material&quot;
        android:paddingBottom=&quot;@dimen/abc_dialog_padding_top_material&quot;&gt;
    
        &lt;TextView
            android:layout_width=&quot;match_parent&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:text=&quot;Title:&quot;/&gt;
    
        &lt;EditText
            android:layout_width=&quot;match_parent&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:gravity=&quot;bottom&quot;
            android:background=&quot;@null&quot;
            android:layout_marginTop=&quot;20dp&quot;/&gt;
        &lt;View
            android:layout_width=&quot;match_parent&quot;
            android:layout_height=&quot;1px&quot;
            android:background=&quot;@color/divider&quot;/&gt;
    &lt;/LinearLayout&gt;

Getting default padding for AlertDialog

Is it possible to have just an image popup/come-up in an Android application? It&#39;s similar to an overriding the normal view of an AlertDialog so that it contains just an image and nothing else. 

**SOLUTION:** *I was able to find an answer thanks to @blessenm&#39;s help. Masking an activity as a dialog seems to be the ideal way. The following is the code that I have used.  This dialog styled activity can be invoked as needed by the application the same way a new activity would be started* 

**ImageDialog.java**

    public class ImageDialog extends Activity {
	
	    private ImageView mDialog;
	
	
	    @Override
	    protected void onCreate(Bundle savedInstanceState) {
		    super.onCreate(savedInstanceState);
		    setContentView(R.layout.your_dialog_layout);
		
	
		
		    mDialog = (ImageView)findViewById(R.id.your_image);
		    mDialog.setClickable(true);
		

            //finish the activity (dismiss the image dialog) if the user clicks 
            //anywhere on the image
		    mDialog.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				finish();
			}
		    });
		
	    }
    }



**your_dialog_layout.xml**

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
    &lt;FrameLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:id=&quot;@+id/image_dialog_root&quot; 
        android:layout_width=&quot;wrap_content&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:background=&quot;@android:color/transparent&quot;
        android:gravity = &quot;center&quot;&gt;
   
	    &lt;ImageView
	    	android:id=&quot;@+id/your_image&quot;  
	    	android:layout_width=&quot;wrap_content&quot;
		    android:layout_height=&quot;wrap_content&quot;
		    android:src = &quot;@drawable/your_image_drawable&quot;/&gt;
  
    &lt;/FrameLayout&gt;


*It is crucial that you set the following style for the activity to accomplish this:*

**styles.xml**

      &lt;style name=&quot;myDialogTheme&quot; parent=&quot;@android:style/Theme.Dialog&quot;&gt;
		&lt;item name=&quot;android:windowNoTitle&quot;&gt;true&lt;/item&gt;
		&lt;item name=&quot;android:windowFrame&quot;&gt;@null&lt;/item&gt;
		&lt;item name=&quot;android:background&quot;&gt;@android:color/transparent&lt;/item&gt;
    	&lt;item name=&quot;android:windowBackground&quot;&gt;@android:color/transparent&lt;/item&gt;
    	&lt;item name=&quot;android:windowIsFloating&quot;&gt;true&lt;/item&gt;
    	&lt;item name=&quot;android:backgroundDimEnabled&quot;&gt;false&lt;/item&gt;
    	&lt;item name=&quot;android:windowContentOverlay&quot;&gt;@null&lt;/item&gt;
	   &lt;/style&gt;



*The final step is to declare this style for the activity in the manifest as follows:*


     &lt;activity android:name=&quot;.ImageDialog&quot; android:theme=&quot;@style/myDialogTheme&quot; /&gt;



Android Image Dialog/Popup

I need to load list cities dynamically from rest webservice and let user choice one city from alert dialog. My code:

    createDialog() {
    
        fetchCities().then((response) {
    
          showDialog(
              context: context,
              builder: (BuildContext context) {
                return AlertDialog(
                  title: Text(&#39;Wybierz miasto&#39;),
                  content: Container(
                    height: 200.0,
                    width: 400.0,
                    child: ListView.builder(
                      shrinkWrap: true,
                      itemCount: response.length,
                      itemBuilder: (BuildContext context, int index) {
                        return ListTile(
                          title: Text(response[index].name),
                          onTap: () =&gt; citySelected(response[index].id),
                        );
                      },
                    ),
                  ),
                );
              }
          );
        });
      }

Result - dialog is always 200x400, even if only 2 cities are available, there is unnecesary room left at the bottom:

How to make dialog width/height to fit actual items size? If I ommit `height` and `width` parameters, I&#39;m getting exception and no dialog shown. In native Android Java I never need to specify any dimensions, because dialog sizes itself automatically to fit. 

How to fix my code to get dialog sized correctly? Note that I don&#39;t know item count, it&#39;s dynamic.

[edit]

As suggested, I wrapped content with column:

    createDialog() {
        fetchCities().then((response) {
          showDialog(
              context: context,
              builder: (BuildContext context) {
                return AlertDialog(
                  title: Text(&#39;Wybierz miasto&#39;),
                  content: Column(
                      mainAxisSize: MainAxisSize.min,
                      children: &lt;Widget&gt;[
                        Container(
                          child: ListView.builder(
                            shrinkWrap: true,
                            itemCount: response.length,
                            itemBuilder: (BuildContext context, int index) {
                              return ListTile(
                                title: Text(response[index].name),
                                onTap: () =&gt; citySelected(response[index].id),
                              );
                            },
                          ),
                        )
                      ]
                  ),
                );
              }
          );
        });
      }

Result - exception:

More generic code to test:

           builder: (BuildContext context) {
             return AlertDialog(

Flutter - Auto size AlertDialog to fit list content

I usually set up some kind of `AlertDialog` to fire off when a user first uses one of my apps and I explain how to use the app and give an overall introduction to what they just downloaded. I also usually load my strings from a `strings.xml` file. 

What I want to do is make one of the words in my string resource clickable like a hyperlink on a web page. Basically you&#39;d have an `AlertDialog` and within the string resource there would be a highlighted word or possibly just a web address that they could press.  I suppose I could just add a button that would take them to the site but I just wanted to know if making a word in your string resource a clickable hyperlink was possible.

Android-Is it possible to add a clickable link into a string resource

Currently when the user opens my app, an `AlertDialog` opens, asking them if they would like to upgrade to the pro version.

I need to add a `CheckBox` to the `AlertDialog` that will make the app no longer show the `AlertDialog` when the user opens the app.

Here is what I have for the `AlertDialog` now:

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle(&quot; MY_TEXT&quot;);
        builder.setMessage(&quot; MY_TEXT &quot;)
               .setCancelable(false)
               .setPositiveButton(&quot;Yes&quot;, new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                       Uri uri = Uri.parse(&quot;market://details?id=MY_APP_PACKAGE&quot;);
                       Intent intent = new Intent (Intent.ACTION_VIEW, uri);
                       startActivity(intent);                          }
               })
               .setNegativeButton(&quot;No&quot;, new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                        dialog.cancel();
                   }
               }).show();

How do I add a `CheckBox` to the `AlertDialog` that will make the app no longer show the `AlertDialog` when the user opens the app?




How to add a check box to an alert dialog

Can I just don&#39;t dismiss my AlertDialog after clicking PositiveButton?

I would like to remain the dialog to show something update on my ArrayAdapter&lt;String&gt; listWords.

This is my code. 


    AlertDialog.Builder sayWindows = new AlertDialog.Builder(MapActivity.this);

    final EditText saySomething = new EditText(MapActivity.this);

	sayWindows.setPositiveButton(&quot;ok&quot;,
				new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {
						say = userName + &quot; Says: &quot;+saySomething.getText();
						showPosition.setText(say);						
					}
				});

	sayWindows.setNegativeButton(&quot;cancel&quot;,
				new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {
						dialog.dismiss();
					}
				});

	sayWindows.setAdapter(listWords, null);
	sayWindows.setView(saySomething);
	sayWindows.create().show();


Android Don&#39;t dismiss AlertDialog after clicking PositiveButton

I create an `AlertDialog` with an `AlertDialog.Builder` and set some items with `setItems()`. The dialog is shown but I cannot see any of the items. All I see is the message.

    final CharSequence[] items = {&quot;Red&quot;, &quot;Green&quot;, &quot;Blue&quot;};

    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(activity);
    dialogBuilder.setMessage(&quot;Pick a color&quot;);
    dialogBuilder.setItems(items, new DialogInterface.OnClickListener() {        
        public void onClick(DialogInterface dialog, int which) {
            // Do anything you want here
        }    
    });

    dialogBuilder.create().show();

If I set the `PositiveButton`, I can see that button just fine. I also tried setting `MultiChoiceItems` and `SingleChoiceItems` but neither of these work either.

AlertDialog&#39;s items not displayed

I have a popup for downloading the audio instruction in my app. What I am trying to do is to change the default text color of &quot;OK&quot; to blue. I tried something but it&#39;s not working. Here is my code:

     private void showDownloadPgmPopup() {

        android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(getActivity());
        builder.setTitle(&quot;Download instructional audio?&quot;);
        builder.setMessage(ParamConstants.AUDIODOWNLOADPERMISSION);
        builder.setNegativeButton(&quot;No&quot;, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                WwDatabaseHelper.storeSelectedWeekAndDay(getActivity(), mSelectedWeekDataModel);
                goToMoveScreen();
            }
        });
        builder.setPositiveButton(&quot;OK&quot;, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                AndroidDownloadFileByProgressBarActivity.StartAudioAssetDownload(getActivity());

            }

        }).create();
        // change the text color of download instruction ok button


        final android.app.AlertDialog dialog = builder.show();
        dialog.setOnShowListener( new DialogInterface.OnShowListener() {
                                      @Override
                                      public void onShow(DialogInterface arg0) {
                                          dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.parseColor(&quot;#ff5722&quot;));
                                      }
                                  });
        dialog.setCanceledOnTouchOutside(false);
        dialog.show();
    }

But the change is not taking effect, can anyone tell me what I am doing wrong?

Iam planing to give create 3 buttons with layout_weight=1, not interested in custom dialog.So I have written below code.It is not working.Always yes button gives me null.
Whats wrong in this code?

        		dialog.setIcon(R.drawable.alert_icon);
        		dialog.setTitle(&quot;title&quot;);

        		yesButton.setLayoutParams(layoutParams);
        		dialog.show();

alertDialog.getButton() method gives null pointer exception android

I&#39;m trying to create a `DialogFragment` using a custom view in an `AlertDialog`. This view must be inflated from xml. In my `DialogFragment` class I have:

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new AlertDialog.Builder(getActivity())
            .setTitle(&quot;Title&quot;)
            .setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, null))
            .setPositiveButton(android.R.string.ok, this)
            .setNegativeButton(android.R.string.cancel, null)
            .create();
    }

I have tried other inflation methods for `.setView()` such as:

    .setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getView(), false))

and

    .setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getTargetFragment().getView(), false))

After setting the target fragment in the fragment that is showing this dialog.

All of these attempts to inflate my custom view result in the following exception:

While if I try to use the `DialogFragment`&#39;s `getLayoutInflator(Bundle)` like this:

    .setView(getLayoutInflater(savedInstanceState).inflate(R.layout.dialog, null))

I get a `StackOverflowError`.

Does anyone know how to inflate a custom view for an `AlertDialog` in a `DialogFragment`?

Problem inflating custom view for AlertDialog in DialogFragment

I created a new application in Eclipse, targeted to Jelly Bean. This is all automatically created code. The manifest sets the application theme to AppName:

	&lt;application
        android:allowBackup=&quot;true&quot;
        android:icon=&quot;@drawable/ic_launcher&quot;
        android:label=&quot;@string/app_name&quot;
        android:theme=&quot;@style/AppTheme&quot; &gt;
        . . . 
        
which translates to AppBaseTheme for styles in the values dir:

    &lt;resources xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;

        &lt;!--
            Base application theme, dependent on API level. This theme is replaced
            by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
        --&gt;
        &lt;style name=&quot;AppBaseTheme&quot; parent=&quot;android:Theme.Light&quot;&gt;
            &lt;!--
                Theme customizations available in newer API levels can go in
                res/values-vXX/styles.xml, while customizations related to
                backward-compatibility can go here.
            --&gt;
        &lt;/style&gt;

        &lt;!-- Application theme. --&gt;
        &lt;style name=&quot;AppTheme&quot; parent=&quot;AppBaseTheme&quot;&gt;
            &lt;!-- All customizations that are NOT specific to a particular API-level can go here. --&gt;
        &lt;/style&gt;

    &lt;/resources&gt;

And values-v14/styles.xml is:

    &lt;resources&gt;

        &lt;!--
            Base application theme for API 14+. This theme completely replaces
            AppBaseTheme from BOTH res/values/styles.xml and
            res/values-v11/styles.xml on API 14+ devices.
        --&gt;
        &lt;style name=&quot;AppBaseTheme&quot; parent=&quot;android:Theme.Holo.Light.DarkActionBar&quot;&gt;
            &lt;!-- API 14 theme customizations can go here. --&gt;
        &lt;/style&gt;

    &lt;/resources&gt;

I then created a confirmation dialog box before quiting:

		case R.id.menu_quit:
			new AlertDialog.Builder(this)
			.setIcon(android.R.drawable.ic_dialog_alert)
			.setTitle(R.string.confirm_title)
			.setMessage(R.string.confirm_text)
			.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
				@Override
				public void onClick(DialogInterface dialog, int which) {
			        finish();    
				}

And the resulting dialog box is:

![resulting dialog box][1]

Why is the ic_dialog_icon so light? It is barely visible. I am using all defaults, I did not modify the theme or any colors, Shouldn&#39;t the system pick an icon wiht more contrast to its background? How can I fix it?

**Edit with fix**  
Following Tomik info I read the documentation for **android.R.attr.alertDialogIcon** and made this fix ( replaced **setIcon()** with **setIconAttribute()** )

			new AlertDialog.Builder(this)
			.setIconAttribute(android.R.attr.alertDialogIcon)
			.setTitle(R.string.confirm_title)
			.setMessage(R.string.confirm_text)
			.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {

Now the dialog looks like this:

Android Dialog theme makes icon too light

I want to display a dialog/popup window with a message to the user that shows &quot;Are you sure you want to delete this entry?&quot; with one button that says &#39;Delete&#39;. When `Delete` is touched, it should delete that entry, otherwise nothing.

I have written a click listener for those buttons, but how do I invoke a dialog or popup and its functionality?


How do I display an alert dialog on Android?

I have many alert dialogs in my app. It is a default layout but I am adding positive and negative buttons to the dialog. So the buttons get the default text color of Android 5 (green). I tried to changed it without success. Any idea how to change that text color?

My Custom dialog:

    public class MyCustomDialog extends AlertDialog.Builder {
    
        public MyCustomDialog(Context context,String title,String message) {
            super(context);
    
            LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
            View viewDialog = inflater.inflate(R.layout.dialog_simple, null, false);
    
            TextView titleTextView = (TextView)viewDialog.findViewById(R.id.title);
            titleTextView.setText(title);
            TextView messageTextView = (TextView)viewDialog.findViewById(R.id.message);
            messageTextView.setText(message);
    
            this.setCancelable(false);
    
            this.setView(viewDialog);
    
        } }


Creating the dialog:

    MyCustomDialog builder = new MyCustomDialog(getActivity(), &quot;Try Again&quot;, errorMessage);
    builder.setNegativeButton(&quot;OK&quot;, new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialogInterface, int i) {
                                ...
                            }
    }).show();



That negativeButton is a default dialog button and takes the default green color from Android 5 Lollipop.

Many thanks

How can I change default dialog button text color in android 5

I have a dialog with `EditText` for input. When I click the &quot;yes&quot; button on dialog, it will validate the input and then close the dialog. However, if the input is wrong, I want to remain in the same dialog. Every time no matter what the input is, the dialog should be automatically closed when I click on the &quot;no&quot; button. How can I disable this? By the way, I have used PositiveButton and NegativeButton for the button on dialog. 



How to prevent a dialog from closing when a button is clicked

I&#39;d like to have an AlertDialog builder that only has one button that says OK or Done or something, instead of the default yes and no.
Can that be done with the standard AlertDialog, or would I have to use something else?

Android AlertDialog Single Button

I need to show a little text message to the users that clicks a button on my Android app, on IOS I just had to create an AlertView that it&#39;s simple to use but with Android i&#39;m struggling because the solution seems x10 times harder. I saw that I need to use a DialogFragment but I can&#39;t understand how to make it work, can someone explain? Also, is my solution right or there is something easier to show a simple text message to users?

Android simple alert dialog

I am trying to migrate from default android `AlertDialog` to the new one included in appCompat-22.1 
So far I understand you only have to import `android.support.v7.app.AlertDialog` package in order to use it.

But how can I style it? For example change the positive/negative button colors, title color, message color and background color?

How to use and style new AlertDialog from appCompat 22.1 and above

My Activity is trying to create an AlertDialog which requires a Context as a parameter. This works as expected if I use:

    AlertDialog.Builder builder = new AlertDialog.Builder(this);

However, I am leery of using &quot;this&quot; as a context due to the potential for memory leaks when Activity is destroyed and recreated even during something simple like a screen rotation. From a [related post on the Android developer&#39;s blog][1]: 

&gt; There are two easy ways to avoid context-related memory leaks. The most obvious one is to avoid escaping the context outside of its own scope. The example above showed the case of a static reference but inner classes and their implicit reference to the outer class can be equally dangerous. The second solution is to use the Application context. This context will live as long as your application is alive and does not depend on the activities life cycle. If you plan on keeping long-lived objects that need a context, remember the application object. You can obtain it easily by calling Context.getApplicationContext() or Activity.getApplication().


But for the `AlertDialog()` neither `getApplicationContext()` or `getApplication()` is acceptable as a Context, as it throws the exception: 

&gt; &quot;Unable to add window — token null is not for an application”

per references: [1][2], [2][3], [3][4], etc.

So, should this really be considered a &quot;bug&quot;, since we are officially advised to use `Activity.getApplication()` and yet it doesn&#39;t function as advertised?

Dialog throwing &quot;Unable to add window — token null is not for an application” with getApplication() as context

I get the lint warning, `Avoid passing null as the view root` when inflating views with `null` as `parent`, like:

    LayoutInflater.from(context).inflate(R.layout.dialog_edit, null);

However, the view is to be used as the content of an `AlertDialog`, using `setView` on `AlertDialog.Builder`, so I don&#39;t know what should be passed as the `parent`.

What do you think the `parent` should be in this case?

&quot;Avoid passing null as the view root&quot; warning when inflating view for use by AlertDialog

From my main `activity`, I need to call an inner class and in a method within the class, I need to show `AlertDialog`. After dismissing it, when the OK button is pressed, forward to Google Play for purchase.

Things work perfectly for most of the times, but for few users it is crashing on `builder.show()` and I can see `&quot;android.view.WindowManager$BadTokenException:` Unable to add window&quot; from crash log. Please suggest.

My code is pretty much like this:

    public class classname1 extends Activity{

      public void onCreate(Bundle savedInstanceState) {
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.&lt;view&gt;); 

        //call the &lt;className1&gt; class to execute
      }

      private class classNamename2 extends AsyncTask&lt;String, Void, String&gt;{

        protected String doInBackground(String... params) {}

        protected void onPostExecute(String result){
          if(page.contains(&quot;error&quot;)) 
          {
            AlertDialog.Builder builder = new AlertDialog.Builder(classname1.this);
            builder.setCancelable(true);
            builder.setMessage(&quot;&quot;);
            builder.setInverseBackgroundForced(true);
            builder.setNeutralButton(&quot;Ok&quot;,new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface dialog, int whichButton){
                dialog.dismiss();
                if(!&lt;condition&gt;)
                {
                  try
                  {
                    String pl = &quot;&quot;; 

                    mHelper.&lt;flow&gt;(&lt;class&gt;.this, SKU, RC_REQUEST, 
                      &lt;listener&gt;, pl);
                  }

                  catch(Exception e)
                  {
                    e.printStackTrace();
                  }
                }  
              }
            });

            builder.show();
          }
        }
      }
    }

I have also seen the error in another alert where I am not forwarding to any other `activity`. It&#39;s simple like this:                                                       

    AlertDialog.Builder builder = new AlertDialog.Builder(classname1.this);
    	builder.setCancelable(true);
    	
    	//if successful
    	builder.setMessage(&quot; &quot;);
    	builder.setInverseBackgroundForced(true);
    	builder.setNeutralButton(&quot;Ok&quot;,new DialogInterface.OnClickListener() {
    		public void onClick(DialogInterface dialog, int whichButton){
    			// dialog.dismiss();
                       }
    	});
    	builder.show();
    }

&quot;android.view.WindowManager$BadTokenException: Unable to add window&quot; on buider.show()

The API says that the Alert Dialog can have one, two or three buttons, but the SDK only allows for a positive and negative button. How then can I add a third button?

How can I add a third button to an Android Alert Dialog?

In the [Android docs on AlertDialog][1], it gives the following instruction and example for setting a custom view in an AlertDialog:

&lt;Blockquote&gt;If you want to display a more complex view, look up the FrameLayout called &quot;body&quot; and add your view to it:&lt;/Blockquote&gt;

    FrameLayout fl = (FrameLayout) findViewById(R.id.body);
    fl.add(myView, new LayoutParams(FILL_PARENT, WRAP_CONTENT));

First off, it&#39;s pretty obvious that `add()` is a typo and is meant to be `addView()`.

I&#39;m confused by the first line using R.id.body. It seems that it&#39;s the body element of the AlertDialog ... but I can&#39;t just enter that in my code b/c it gives a compile error. Where does R.id.body get defined or assigned or whatever?

Here&#39;s my code. I tried to use `setView(findViewById(R.layout.whatever)` on the builder but it didn&#39;t work. I&#39;m assuming because I didn&#39;t manually inflate it?

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle(&quot;Title&quot;)
        .setCancelable(false)
        .setPositiveButton(&quot;Go&quot;, new DialogInterface.OnClickListener() {
    					
        @Override
        public void onClick(DialogInterface dialog, int id) {
            EditText textBox = (EditText) findViewById(R.id.textbox);
            doStuff();
        }
    });
    
    FrameLayout f1 = (FrameLayout)findViewById(R.id.body /*CURRENTLY an ERROR*/);
    f1.addView(findViewById(R.layout.dialog_view));
    
    AlertDialog alert = builder.create();
    alert.show();

How can I change the color of AlertDialog title and the color of the line under it

Recently I switched from support library to com.google.android.material:material:1.0.0

But now I have a problem, in this pages there&#39;s a note https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md

&gt; Note: Using a Material Components theme enables a custom view inflater which replaces default components with their Material counterparts. Currently, this only replaces Button XML components with MaterialButton.

And the theme I am using 

    Theme.MaterialComponents.Light.NoActionBar


does exactly what it says in that note, it replaces AlertDialog Buttons to MaterialButtons but the problem is that by default MaterialButtons are colored background and now the buttons looks like this: [![enter image description here][1]][1]

MaterialComponents theme alert dialog buttons

I had created an AlertDialog which is working fine. It is disappearing, if I press:&lt;br&gt; 
1) escape keyboard button or &lt;br&gt;
2) back button using mouse &lt;br&gt;
To make it stay focused even on above stated conditions, I had added &#39;.setCancelable(false)&#39; statement while building. But, I still see dialog disappearing. Where is the problem? 
Please help.&lt;br&gt;

    return new AlertDialog.Builder(getActivity())
                    .setIcon(R.drawable.alert_dialog_icon)

Yes, I know there&#39;s AlertDialog.Builder, but I&#39;m shocked to know how difficult (well, at least not programmer-friendly) to display a dialog in Android.

I have searched more... but i don&#39;t have any right idea to clear this.

What i want is, when loading this page, layout should be added and dialog should be shown.

Please help me to clear this error

**Note:** I have tried this also

    @Override
    	protected void onResume() {
        super.onResume();
    		runOnUiThread(new Runnable() {
    		    public void run() {
    		    	showInfoMessageDialog(&quot;Please check your network connection&quot;,&quot;Network Alert&quot;);
    		    }
    		});

android activity has leaked window com.android.internal.policy.impl.phonewindow$decorview Issue

When developing an Android app, I&#39;ve read that it&#39;s recommended to use `DialogFragment ` instead of using directly an `AlertDialog` to show alerts and confirmations.

This is done, for example, on DialogFragment&#39;s Documentation: http://developer.android.com/reference/android/app/DialogFragment.html

People also say they prefer this here:
https://stackoverflow.com/questions/7977392/android-dialogfragment-vs-dialog

I would like to know the advantages of this approach, since the code becomes more complex.

Thanks

DialogFragment advantages over AlertDialog

I have implemented an `AlertDialog` with normal negative and positive button click listeners. 

When I called `new DialogInterface.OnClickListener()` it was showing me a suggestion saying: `Anonymous new DialogInterface.OnClickListener() can be replaced with lambda`. I know it&#39;s not an error or something big but what exactly is this suggestion and what can I do about it?


    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setPositiveButton(&quot;Text&quot;, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            // do something here
        }
    });

`Android Studio V1.2.1.1
 compileSdkVersion 22
 buildToolsVersion &quot;22.0.0&quot;
 minSdkVersion 14
 targetSdkVersion 22`


What does it mean that a Listener can be replaced with lambda?

I wrote android code that shows a pop-up dialog but I want to change the background color from black to white , and then the color of the writing.

This is the dialog&#39;s code: 

    mPrefs = PreferenceManager.getDefaultSharedPreferences(this);

        Boolean welcomeScreenShown = mPrefs.getBoolean(welcomeScreenShownPref, false);

        if (!welcomeScreenShown) {


            String whatsNewText = getResources().getString(R.string.Text);
            new AlertDialog.Builder(this).setMessage(whatsNewText).setPositiveButton(
                    R.string.ok, new DialogInterface.OnClickListener(){
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            }).show();
            SharedPreferences.Editor editor = mPrefs.edit();
            editor.putBoolean(welcomeScreenShownPref, true);
            editor.commit(); // Very important to save the preference
        }

Change the background color of a pop-up dialog

I want to display an alert dialog in my app. I am using fragments. I tried the below code to do this:

 

     AlertDialog ad = new AlertDialog.Builder(context)
				.create();
		ad.setCancelable(false);
		ad.setTitle(title);
		ad.setMessage(message);
		ad.setButton(context.getString(R.string.ok_text), new DialogInterface.OnClickListener() {

			public void onClick(DialogInterface dialog, int which) {
				dialog.dismiss();
			}
		});
    ad.show();
but it was crashing and the error in logcat was:

 
 &gt; 04-18 15:23:01.770: E/AndroidRuntime(9424): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

From internet I came to know that the crash is due to context issue. I had given context as

    context = this.getActivity().getApplicationContext();

I don&#39;t know what is the problem with this. Can anybody help me?	

How to display AlertDialog in a Fragment?

I have been having this problem in an application I am building. Please ignore all of the design shortcomings and lack of best practice approaches, this is purely to show an example of what I cannot solve.

I have `DialogFragment` which returns a basic `AlertDialog` with a custom `View` set using `AlertDialog.Builder.setView()`. If this `View` has a specific size requirement, how do I get the `Dialog` to correctly resize itself to display all of the content in the custom `View`?

This is the example code I have been using:

    package com.test.test;
    
    import android.os.Bundle;
    import android.app.Activity;
    import android.app.AlertDialog;
    import android.app.Dialog;
    import android.app.DialogFragment;
    import android.content.Context;
    import android.graphics.Canvas;
    import android.graphics.Color;
    import android.graphics.Paint;
    import android.graphics.Paint.Style;
    import android.view.Gravity;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.WindowManager;
    import android.view.View.OnClickListener;
    import android.view.ViewGroup;
    import android.view.ViewGroup.LayoutParams;
    import android.widget.ArrayAdapter;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.FrameLayout;
    import android.widget.LinearLayout;
    import android.widget.Spinner;
    import android.widget.TextView;
    
    public class MainActivity extends Activity {
    	
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    			
    		// Use a button for launching
    		Button b = new Button(this);
    		b.setText(&quot;Launch&quot;);
    		b.setOnClickListener(new OnClickListener() {	
    			@Override
    			public void onClick(View v) {
    				// Launch the dialog
    				myDialog d = new myDialog();
    				d.show(getFragmentManager(), null);
    			}
    		});
    		
    		setContentView(b);
    	}
    	
    	public static class myDialog extends DialogFragment {
    		
    		@Override
    		public Dialog onCreateDialog(Bundle savedInstanceState) {			
    			// Create the dialog
    			AlertDialog.Builder db = new AlertDialog.Builder(getActivity());
    			db.setTitle(&quot;Test Alert Dialog:&quot;);
    			db.setView(new myView(getActivity()));
    			
    			return db.create();
    		}
    		
    		protected class myView extends View {
    			Paint p = null;
    			
    			public myView(Context ct) {
    				super(ct);
    
    				// Setup paint for the drawing
    				p = new Paint();
    				p.setColor(Color.MAGENTA);
    				p.setStyle(Style.STROKE);
    				p.setStrokeWidth(10);
    			}
    			
    			@Override
    			protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    				setMeasuredDimension(800, 300);
    			}
    			
    			@Override
    			protected void onDraw(Canvas canvas) {
    				// Draw a rectangle showing the bounds of the view
    				canvas.drawRect(0, 0, getMeasuredWidth(), getMeasuredHeight(), p);
    			}
    		}
    	}
    }

A `Button` is created, which opens the `DialogFragment` on a click. The custom `View` (`myView`) is required to have a width of 800 and height of 300 which is correctly set in an override of `onMeasure()`. This `View`, draws its measured bounds in magenta for debugging purposes.

The 800 width is wider than the default `Dialog` size on my device, but is clipped rather than stretching correctly.

I have looked through the following solutions:

 - https://stackoverflow.com/questions/8456143/dialogfragment-getdialog-returns-null
 - https://stackoverflow.com/questions/4406804/how-to-control-the-width-and-height-of-default-alert-dialog-in-android
 - https://stackoverflow.com/questions/8835931/size-of-alert-dialog-or-custom-alert-dialog

I have deduced the following two coding approaches:

 1. Get the `WindowManager.LayoutParams` of the `Dialog` and override them using `myDialog.getDialog().getWindow().get/setAttributes()`
 2. Using the `setLayout(w, h)` method through `myDialog.getDialog().getWindow().setLayout()`

I have tried them everywhere I can think of (overriding `onStart()`, in a `onShowListener`, after the `Dialog` is created and shown, etc) and can generally get both methods to work correctly if the `LayoutParams` are supplied a **specific value**. But whenever `WRAP_CONTENT` is supplied, nothing happens.

Any suggestions?

**EDIT:**

Screenshot of the situation:
![enter image description here][1]

Screenshot of a specific value (note 900 is entered here, 850 doesn&#39;t cover the entire width of the View, which makes sense given the entire window is being adjusted. So that provides - if another was needed - reason why `WRAP_CONTENT` is essential / fixed values are not appropriate):
