I&#39;m trying to open a dialog window, but every time I try to open it it throws this exception:

    Uncaught handler: thread main exiting due to uncaught exception
    android.view.WindowManager$BadTokenException: 
         Unable to add window -- token null is not for an application
      at android.view.ViewRoot.setView(ViewRoot.java:460)

      at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:91)
      at android.app.Dialog.show(Dialog.java:238)
      at android.app.Activity.showDialog(Activity.java:2413)

I&#39;m creating it by calling `showDialog` with the display&#39;s id. The `onCreateDialog` handler logs fine and I can step through it without an issue, but I&#39;ve attached it since it seems like I&#39;m missing something:


    @Override
    public Dialog onCreateDialog(int id)
    {
    	Dialog dialog;
    	Context appContext = this.getApplicationContext();
    	switch(id)
    	{
			case RENAME_DIALOG_ID:
				Log.i(&quot;Edit&quot;, &quot;Creating rename dialog...&quot;);
		    	dialog = new Dialog(appContext);
		    	dialog.setContentView(R.layout.rename);
				dialog.setTitle(&quot;Rename &quot; + noteName);
		    	break;
		    default:
		    	dialog = null;
		    	break;
    	}
		return dialog;    	
    }

Is there something missing from this? Some questions have talked about having this problem when creating a dialog from `onCreate`, which happens because the activity isn&#39;t created yet, but this is coming from a call from a menu object, and the `appContext` variable seems like it is correctly populated in the debugger.

Android 1.6: &quot;android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application&quot;

I&#39;m using the google example to insert a datepicker inside my app using a dialogfragment  
http://developer.android.com/guide/topics/ui/controls/pickers.html

But I&#39;m not sure how to get date after set it (not java expert). Dialog and datepicker runs ok and I can log that date is correctely set but, how can i do to get a callback executed on parent activity?

This is my Dialog fragment

    public class DatePickerFragment extends DialogFragment implements
    		DatePickerDialog.OnDateSetListener {
    
    	@Override
    	public Dialog onCreateDialog(Bundle savedInstanceState) {
    		// Use the current date as the default date in the picker
    		final Calendar c = Calendar.getInstance();
    		int year = c.get(Calendar.YEAR);
    		int month = c.get(Calendar.MONTH);
    		int day = c.get(Calendar.DAY_OF_MONTH);
    
    		// Create a new instance of DatePickerDialog and return it
    		return new DatePickerDialog(getActivity(), this, year, month, day);
    	}
    
    	public void onDateSet(DatePicker view, int year, int month, int day) {
    		**Log.w(&quot;DatePicker&quot;,&quot;Date = &quot; + year);**
    	}
    }

...and I call dialog from my activity with...

	public void showDatePickerDialog(View v) {
		DialogFragment newFragment = new DatePickerFragment();
		newFragment.show(getSupportFragmentManager(), &quot;datePicker&quot;);
	}

What is the correct way to call a method in my parent activity instead Log.w? I suppose that is something related with passing a callback as parameter or something but most of references I found on internet are about previous versions without dialogfragments

EDIT: not sure if it&#39;s important but parent activity is declared as:

    public class EditSessionActivity extends FragmentActivity {

**SOLUTION: thanks to Lecho user this is the way to do it**

DatePickerFragmennt.class

    public class DatePickerFragment extends DialogFragment{
    
    	@Override
    	public Dialog onCreateDialog(Bundle savedInstanceState) {
    		// Use the current date as the default date in the picker
    		final Calendar c = Calendar.getInstance();
    		int year = c.get(Calendar.YEAR);
    		int month = c.get(Calendar.MONTH);
    		int day = c.get(Calendar.DAY_OF_MONTH);
    
    		// Create a new instance of DatePickerDialog and return it
    		return new DatePickerDialog(getActivity(), (EditSessionActivity)getActivity(), year, month, day);
    	}
    
    }

...and parent activity EditSessionActivity.class...

    public class EditSessionActivity extends FragmentActivity implements OnDateSetListener {
    ...
    	@Override
    	public void onDateSet(DatePicker view, int year, int month, int day) {
    		//do some stuff for example write on log and update TextField on activity
    		Log.w(&quot;DatePicker&quot;,&quot;Date = &quot; + year);
    		((EditText) findViewById(R.id.tf_date)).setText(&quot;Date = &quot; + year);
    	}

Get date from datepicker using dialogfragment

I&#39;ve been trying to show a &quot;Do you want to exit?&quot; type of dialog when the user attempts to exit an Activity.  

However I can&#39;t find the appropriate API hooks.  `Activity.onUserLeaveHint()` initially looked promising, but I can&#39;t find a way to stop the Activity from finishing.

Android Activity as a dialog

Google recommends that we use `DialogFragment` instead of a simple `Dialog` by using `Fragments API`, but it is absurd to use an isolated `DialogFragment` for a simple Yes-No confirmation message box. What is the best practice in this case?

Android DialogFragment vs Dialog

Let&#39;s say I specify the layout of my `DialogFragment` in an xml layout file named `my_dialog_fragment.xml` and I specify the `layout_width` and `layout_height` values of its root view to a fixed value (e.g. `100dp`). I then inflate this layout in my `DialogFragment`&#39;s `onCreateView(...)` method as follows:

    View view = inflater.inflate(R.layout.my_dialog_fragment, container, false);

Sadly, I find that when my `DialogFragment` appears, it does not respect the `layout_width` and `layout_height` values specified in its xml layout file and instead shrinks or expands depending on its content. Anyone know whether or how I can get my `DialogFragment` to respect the `layout_width` and `layout_height` values specified in its xml layout file? At the moment I&#39;m having to specify the width and height of the `Dialog` again in my `DialogFragment`&#39;s `onResume()` method as follows:

    getDialog().getWindow().setLayout(width, height);

The problem with this is that I have to remember to make any future changes to the width and height in two places.

**What I am trying to do:** I am trying to make a custom dialog in android With rounded corners.

**What is happening:** I am able to make custom dialog but it doesn&#39;t have rounded corners. I tried adding a selector but still I couldn&#39;t achieve rounded corners.

Below is my code for the same:

How to make custom dialog with rounded corners in android

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.

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?

I have some fragments that need to show a regular dialog. On these dialogs the user can choose a yes/no answer, and then the fragment should behave accordingly.

Now, the `Fragment` class doesn&#39;t have an `onCreateDialog()` method to override, so I guess I have to implement the dialogs outside, in the containing `Activity`. It&#39;s ok, but then the `Activity` needs to report back the chosen answer somehow to the fragment. I could of course use a callback pattern here, so the fragment registers itself at the `Activity` with a listener class, and the Activity would report back the answer thru that, or something like that.

But this seems to be quite a big mess for a simple task as displaying a &quot;simple&quot; yes-no dialog in a fragment. Also, this way my `Fragment` would be less self-contained.

Is there some cleaner way to do this?

**Edit:**

The answer to this question doesn&#39;t really explain in detail how one should use DialogFragments to display dialogs from Fragments. So AFAIK, the way to go is:

1. Display a Fragment.
2. When needed, instantiate a DialogFragment.
3. Set the original Fragment as the target of this DialogFragment, with `.setTargetFragment()`.
4. Show the DialogFragment with .show() from the original Fragment.
5. When the user chooses some option on this DialogFragment, notify the original Fragment about this selection (e.g. the user clicked &#39;yes&#39;), you can get the reference of the original Fragment with .getTarget().
6. Dismiss the DialogFragment.

Show dialog from fragment?

I need to create a dialog over a fragment (that takes up the whole screen). The dialog needs to be a floating dialog that will be positioned over the fragment with the fragment darkened out outside of the fragment..

For the custom Dialog, i have a linearLayout that has curved edges, no matter what i do, the dialog has a black bordering on all sides (very small). I&#39;ve tried everything to make it transparent and go away (so that all of the dialog is just the linear layout - curved box)

For the DialogFragment, this is what I have for onCreateView

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
		LinearLayout layout =(LinearLayout)inflater.inflate(R.layout.custom_dialog, null);
		LinearLayout item = (LinearLayout)layout.findViewById(R.id.display_item);
		populateItemData(item, inflater);
		return layout;
    }

custom_dialog is just a LinearLayout that has android:backgroung set to #000000

This is my style for the custom Dialog

    &lt;style name=&quot;CustomDialog&quot; parent=&quot;android:style/Theme.Dialog&quot;&gt;
        &lt;item name=&quot;android:windowBackground&quot;&gt;@null&lt;/item&gt;
        &lt;item name=&quot;android:windowNoTitle&quot;&gt;true&lt;/item&gt;
        &lt;item name=&quot;android:windowIsFloating&quot;&gt;true&lt;/item&gt;
        &lt;item name=&quot;android:windowIsTranslucent&quot;&gt;true&lt;/item&gt; 
        &lt;item name=&quot;android:alwaysDrawnWithCache&quot;&gt;false&lt;/item&gt;
        &lt;item name=&quot;android:windowContentOverlay&quot;&gt;@null&lt;/item&gt;
    &lt;/style&gt;

I tried all kinds of combinations in this style (from what I&#39;ve seen online) and I can&#39;t get rid of that annoying black bordering, I can paint it white or any other color if i set that LinearLayout background to anything other than #000000... 

I&#39;ve spent literally 3-4 hours on this, i hope someone else can help out...



Can&#39;t make the custom DialogFragment transparent over the Fragment

My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler. This all works fine, except when screen orientation changes while the dialog is up (and the background thread is going). At this point the app either crashes, or deadlocks, or gets into a weird stage where the app does not work at all until all the threads have been killed.

How can I handle the screen orientation change gracefully?

The sample code below matches roughly what my real program does:

    public class MyAct extends Activity implements Runnable {
        public ProgressDialog mProgress;

        // UI has a button that when pressed calls send
    
        public void send() {
             mProgress = ProgressDialog.show(this, &quot;Please wait&quot;, 
                          &quot;Please wait&quot;, 
                          true, true);
            Thread thread = new Thread(this);
            thread.start();
        }
    
        public void run() {
            Thread.sleep(10000);
            Message msg = new Message();
            mHandler.sendMessage(msg);
        }
    
        private final Handler mHandler = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                mProgress.dismiss();
            }
        };
    }

I have tried to dismiss the progress dialog in onSaveInstanceState, but that just prevents an immediate crash. The background thread is still going, and the UI is in partially drawn state. Need to kill the whole app before it starts working again.


How to handle screen orientation change when progress dialog and background thread active?

How do I maintain the new Immersive Mode when my activities display a custom Dialog?

I am using the code below to maintain the Immersive Mode in Dialogs, but with that solution, the NavBar appears for less than a second when I start my custom Dialog, then it disappears.

The following video explains the issue better (look at the bottom of the screen when the NavBar appears): http://youtu.be/epnd5ghey8g

How do I avoid this behavior?

All my custom Dialogs call this method in their `onCreate(. . .)` method:

    /**
     * Copy the visibility of the Activity that has started the dialog {@link mActivity}. If the
     * activity is in Immersive mode the dialog will be in Immersive mode too and vice versa.

**EDIT - THE SOLUTION (thanks to Beaver6813, look his answer for more details) :**

All my custom dialogs override the show method in this way:

    /**
     * An hack used to show the dialogs in Immersive Mode (that is with the NavBar hidden). To
     * obtain this, the method makes the dialog not focusable before showing it, change the UI
     * visibility of the window like the owner activity of the dialog and then (after showing it)
     * makes the dialog focusable again.
     */
    @Override
    public void show() {
        // Set the dialog to not focusable.
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);

        copySystemUiVisibility();

        // Show the dialog with NavBar hidden.
        super.show();

        // Set the dialog to focusable again.
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    }

How do I maintain the Immersive Mode in Dialogs?

in my application my created custom dialog dont have full height and i can not change and customize that.for example see this screen shot:

![enter image description here][1]
My code:

    final Dialog contacts_dialog = new Dialog(ActivityGroup.this, R.style.theme_sms_receive_dialog);
    contacts_dialog.setContentView(R.layout.dialog_schedule_date_time);
    contacts_dialog.setCancelable(true);
    contacts_dialog.setCanceledOnTouchOutside(true);
    contacts_dialog.show();

layout:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;

            android:orientation=&quot;horizontal&quot;
            android:padding=&quot;4dp&quot; &gt;
    
            &lt;TextView
                android:id=&quot;@+id/TextView21&quot;
                android:layout_width=&quot;fill_parent&quot;
                android:layout_height=&quot;fill_parent&quot;
                android:layout_marginRight=&quot;5dp&quot;
                android:layout_weight=&quot;2&quot;
                android:gravity=&quot;center_vertical|right&quot;
                android:text=&quot;@string/choose_schedule_time_date&quot;
                android:textColor=&quot;#ffffff&quot;
                android:textSize=&quot;14sp&quot;
                android:textStyle=&quot;bold&quot; /&gt;
    
            &lt;ImageView
                android:id=&quot;@+id/ImageView03&quot;
                android:layout_width=&quot;50dp&quot;
                android:layout_height=&quot;50dp&quot;
                android:layout_marginTop=&quot;0dp&quot;
                android:background=&quot;@drawable/icon_scudule_time&quot; /&gt;
        &lt;/LinearLayout&gt;
    
    &lt;/LinearLayout&gt;


Style:

    &lt;style name=&quot;theme_sms_receive_dialog&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: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;numberPickerStyle&quot;&gt;@style/NPWidget.Holo.Light.NumberPicker&lt;/item&gt;
    &lt;/style&gt;

Android get full width for custom Dialog

I want to be able to create a Dialog that allows the user to pick a number from a specified range. 

I know that there are existing widgets(like those from quietlycoding and the one by SimonVT) that already does this but I&#39;m having hard time integrating those properly into my application. Also, those are primarily widgets. I want something that is very similar to the one in the android developers page tutorials.

I also checked the documentation for the NumberPicker and it said to go check the TimePicker and DatePicker for examples but they only show how to use Time and Date pickers and I&#39;m having a hard time feeling my way around the code and trying to convert the Time Picker to just a normal Number Picker. Does anyone have any idea where to start? I&#39;ve been looking for solutions for the last 3 hours to no avail. 

How to create a number picker dialog?

I started using DialogFragment, because they are working nicely through orientation changes, and stuff. But there is nasty problem I encountered.

I have `AsyncTask` that shows progress DialogFragment and dismisses it `onPostExecute`. Everything works fine, except when `onPostExecute` happens while application is in background (after pressing Home button, for example). Then I got this error on DialogFragment dismissing - &quot;`Can not perform this action after onSaveInstanceState`&quot;. Doh. Regular dialogs works just fine. But not FragmentDialog.

So I wonder, what is the proper way of dismissing DialogFragment while application is in background? I haven&#39;t really worked with Fragments a lot, so I think that I&#39;m just missing something.

Proper way of dismissing DialogFragment while application is in background

I want to create a custom dialog box like below 

![enter image description here][1]

I have tried the following things.

 1. I created a subclass of **AlertDialog.Builder** and used a custom Title and Custom Content View and used that but the result was not as expected.

 2. Another attempt was to subclass **DialogFragment** and customize the dialog inside onCreateDialog that but result was not as expected.

 3. Then I tried using a plain **Dialog** class. The result was not as expected.

In all three cases, the problem is when I overlook the title view the size of the dialog is not as expected and when I use Title view the result is there is a thick border around the content view (which really looks bad). Now I have two questions in my mind...

1. How can I achieve that? As I have already tried so many things, a direct answer will be more appreciated.

2. What is the best way to show an error or alert dialog in an android app?

**EDIT**
[Android Developer Documentation][2] recommends that we should use either DialogFragments or Dialogs for showing Error / Alert Messages to the user. However at one point they say ...

&gt;Tip: If you want a custom dialog, you can instead display an Activity as a dialog instead of using the Dialog APIs. Simply create an activity and set its theme to Theme.Holo.Dialog in the &lt;activity&gt; manifest element.

**What is the meaning of that? Isn&#39;t it too much to use an Activity just for showing an error message???**
