`Clickable` means that it can be clicked by a pointer device or be tapped by a touch device. `Focusable` means that it can gain the focus from an input device like a keyboard. Input devices like keyboards cannot decide which view to send its input events to based on the inputs itself, so they send them to the view that has _focus_.

`Focusable` means ACTION_UP event will occur. It will gain it and it won&#39;t release it.

`Clickable` means ACTION_DOWN first and ACTION_UP at the end. It will gain and release it at the end.

I can&#39;t find any example of using this method, all examples give the second parameter &quot;null&quot;.
I heard that this method used for sorting classes according to more than one criterion but no example where found.

    public class Student implements Comparable&lt;Student&gt; {

	public Student(String name, int age) {
		this.name = name;
		this.age = age;

	@Override
	public int compareTo(Student o) {
		Integer myAge = age;
		Integer oAge = o.age;
		return myAge.compareTo(oAge);
	}

How to assign padding to Listview item divider line

I am unable to understand 

1. START_STICKY,
2. START_NOT_STICKY and 
3. START_REDELIVER_INTENT 

Can anyone explain clearly with examples.

I went through [this][1] link but couldn&#39;t understand it clearly.

What is START_STICKY,START_NOT_STICKY and START_REDELIVER_INTENT Service

Per the Android Documentation it states:

&gt; There is normally no need to subclass Application. In most situation,
&gt; static singletons can provide the same functionality in a more modular
&gt; way. If your singleton needs a global context (for example to register
&gt; broadcast receivers), the function to retrieve it can be given a
&gt; Context which internally uses `Context.getApplicationContext()` when
&gt; first constructing the singleton.

How do I go about creating a static singleton that has global context so that it survives the running activity changing in my app?  Is it enough to have a static context which references the getApplicationContext()?

Android Singleton with Global Context

My android program has a `class A`, which has two `static inner class`. They are found to be stripped from `.dex` after applying proguard.


    public class A{

      ...
      static class B{
        ...
      }

      static class C{
        ...
      }
    }

I have put the following lines in proguard.flags, but seem no luck. 

    -keep class com.xxx.A
    -keep class com.xxx.A$*

Any hint?



Android proguard, keep inner class

I have an EditText-Field and set an OnFocusChangeListener for it. When it has lost focus, a method is called, which checks the value of the EditText with one in the database. If the return-value of the method is true, a toast is shown and the focus should get back on the EditText again. The focus should always get back on the EditText and the keyboard should show, until the return-value of the method is false.

EDIT: I think, I haven&#39;t made my real problem perfectly clear yet: No other Item on the Screen should be able to edit, until the value of the EditText is edited to a value, which makes the method &quot;checkLiganame(liganame)&quot; return false. Only the EditText-Field should be editable.


here is my code (which doesn&#39;t work for me):

    final EditText Liganame = (EditText) findViewById(R.id.liganame);

		Liganame.setOnFocusChangeListener(new OnFocusChangeListener() {
			
			@Override
			public void onFocusChange(View v, boolean hasFocus) {
				if (!hasFocus) {
					
					String liganame = Liganame.getText().toString();
					
					
					if (checkLiganame(liganame)) {
						Toast toast = Toast.makeText(CreateTableActivity.this,
								&quot;Dieser Liganame ist bereits vergeben&quot;,
								Toast.LENGTH_SHORT);
						toast.show();
						Liganame.requestFocus();
					}
				}


and the method:

    public boolean checkLiganame(String liganame) {
		boolean found = false;

		DatabaseHelper databaseHelper = new DatabaseHelper(this);
		SQLiteDatabase db = databaseHelper.getReadableDatabase();

		Cursor cursor = db.query(&quot;liga&quot;, new String[] { &quot;liganame&quot; },
				&quot;liganame = &#39;&quot; + liganame + &quot;&#39;&quot;, null, null, null, null);
		Log.i(&quot;Liganame: &quot;, String.valueOf(cursor));

		db.close();
		if (cursor != null) {
			found = true;
		}

		return found;
	}


This code leads to the following result: After the EditText has lost focus, the focus jumps back to EditText, but I can&#39;t edit the text anymore.


EDIT2: Changed my code. Scenario:

I click on the first EditText and put a String in it, which is already in the database. The toast is showing. Now I can&#39;t edit my String anymore. I click &quot;next&quot; on the keyboard and the focus stays on the first EditText. I try to edit my String, but nothing happens. Instead my new String is showing in the second EditText. I click on the back-arrow of my device and reclick on the first and second EditText --&gt; no keyboard is showing.

Here is my new Code:

    public class CreateTableActivity extends Activity implements
		OnFocusChangeListener {

	private EditText Liganame, Mannschaftsanzahl;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.create_league);
		
		Liganame = (EditText) findViewById(R.id.liganame);
		Liganame.setOnFocusChangeListener(this);
		Mannschaftsanzahl = (EditText) findViewById(R.id.mannschaftsanzahl);
		Mannschaftsanzahl.setOnFocusChangeListener(this);

		final Button save_button = (Button) findViewById(R.id.create_tabelle_speichern_button);

		OnClickListener mCorkyListener = new OnClickListener() {
			public void onClick(View v) {
				ButtonClick();
			}
		};
		save_button.setOnClickListener(mCorkyListener);

		

	}

	@Override
	public void onFocusChange(View v, boolean hasFocus) {
		String liganame = Liganame.getText().toString();

		if (checkLiganame(liganame)) {
			if (Liganame.requestFocus()) {
				getWindow()
						.setSoftInputMode(
								WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
				Mannschaftsanzahl.clearFocus();
				Toast.makeText(CreateTableActivity.this,
						&quot;Dieser Liganame ist bereits vergeben&quot;,
						Toast.LENGTH_SHORT).show();
			}
		}
	}

Set Focus on EditText

Please explain me the issue about soft keyboard.
For example, I have an EditText on my activity or dialogfragment or fragmentactivity, whatever.
here it is:

    &lt;EditText
        android:id=&quot;@+id/edPswrd&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:ems=&quot;10&quot;
        android:inputType=&quot;textPassword&quot; &gt;

        &lt;requestFocus /&gt;
    &lt;/EditText&gt;

When it shows for the first time I do not see the soft keyboard and have to press editText for it to receive focus and the keyboard appears. Another activities are different, when it appears on screen the keyboard are loaded without any help.
I thought that 

&gt; &lt; requestFocus /&gt;

means that EditText will be focused and keyboard will appear, but I am wrong.

How should I manage what component will receive focus and keyboard will **automatically** appear.

Show keyboard automatically

I have a web form with a text box in it. How do I go about setting focus to the text box by default?

Something like this:

&lt;!-- language: lang-html --&gt;

    &lt;body onload=&#39;setFocusToTextBox()&#39;&gt;

so can anybody help me with it? I don&#39;t know how to set focus to the text box with JavaScript.

&lt;!-- language: lang-html --&gt;

    &lt;script&gt;
      function setFocusToTextBox(){
        //What to do here
      }
    &lt;/script&gt;

How can I set focus on an element in an HTML form using JavaScript?

I&#39;ve read the other questions discussing this, and all of them work for my layouts, **except** for the very first one created.

At the moment, this is at the top of my `onCreate` method:

    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

^ That makes it so at least the keyboard doesn&#39;t pop up on startup, but the `EditText` is still focused on.

This is the `XML` for my `EditText`:

&lt;!-- language: xml --&gt;

    &lt;EditText
        android:id=&quot;@+id/password&quot;
        android:layout_width=&quot;wrap_content&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:layout_below=&quot;@+id/changePass&quot;
        android:layout_centerHorizontal=&quot;true&quot;
        android:layout_marginTop=&quot;167dp&quot;
        android:ems=&quot;10&quot;
        android:imeOptions=&quot;flagNoExtractUi&quot;
        android:inputType=&quot;textPassword&quot;
        android:maxLength=&quot;30&quot; &gt;
    &lt;/EditText&gt;

This is what it looks like when I bring up my activity:

![enter image description here][1]

The problem is that with some phones, when an `EditText` is focused like this, they can&#39;t write in it. I want it to **not** focus.

What I&#39;ve done works for the next layouts brought up in that it the `EditTexts` are not focused on and would look more like this:

![enter image description here][2]

Notice that it&#39;s the same layout, though. This is the screen after the user has been brought back to this screen, which would indicate nothing wrong with the `XML` because this is the same `XML`, but the problem is that the `EditText` is only focused on when the activity is created.

I&#39;ve done research and all of the other questions don&#39;t help me with this (they did however help the keyboard not show up, thankfully). How can I make it so the `EditText` on startup will look like the second screenshot, rather than the first?

How to make EditText not focused when creating Activity

How can I acquire the currently focused element/control in WPF from code that is part of neither a window nor an user control? 


Get currently focused element/control in a WPF window

Until now, when I wanted to stop the user from pressing the button, I would set the `button.setClickable(false);` and usually change the text to some kind of grey colour (to let the user know that the button is disabled). Today I stumbled upon the `setEnabled()` property.

So I went to the documentation to see the method&#39;s explanation below:

    setEnabled(boolean enabled)
       Set the enabled state of this view.

What does this even mean? What is the difference between enable state/clickable state and disabled state/not clickable state? Could someone please explain what is the difference between doing what I was doing previously, using the clickable property and using the `setEnabled()` property? What should be used when? I searched Stack Overflow but could not find anything related. 


setEnabled() vs setClickable(), what is the difference?

I want to make a part of a text tapable so I can call a function on it. Also I want to have control over the style of the tapable text. In the best case I can also increase the size of the tapable area to for example 42px.
