You want to disable or dismiss a virtual Keyboard?

If you want to just dismiss it you can use the following lines of code in your button's on click Event

<pre><code>InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);
</code></pre>

blocks|key|1162394|text|上面的解决方案并不适用于所有设备，而且它使用EditText作为参数。这是我的解决方案，只需调用这个简单的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1162395|private+void+hideSoftKeyBoard()+{

The solution above doesn't work for all device and moreover it's using EditText as a parameter. This is my solution, just call this simple method:

<pre><code>private void hideSoftKeyBoard() {
 InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);

 if(imm.isAcceptingText()) { // verify if the soft keyboard is open 
 imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
 }
}

Here's a Kotlin solution (mixing the various answers in thread)

Create an extension function (perhaps in a common ViewHelpers class)

<pre><code>fun Activity.dismissKeyboard() {
 val inputMethodManager = getSystemService( Context.INPUT_METHOD_SERVICE ) as InputMethodManager
 if( inputMethodManager.isAcceptingText )
 inputMethodManager.hideSoftInputFromWindow( this.currentFocus.windowToken, /*flags:*/ 0)
}
</code></pre>

Then simply consume using:

<pre><code>// from activity
this.dismissKeyboard()

// from fragment
activity.dismissKeyboard()
</code></pre>

The first solution with InputMethodManager worked like a champ for me, the getWindow().setSoftInputMode method did not on android 4.0.3 HTC Amaze. 

@Ethan Allen, I did not need to make the edit text final. Maybe you are using an EditText inner class that you declared the containing method? You could make the EditText a class variable of the Activity. Or just declare a new EditText inside the inner class / method and use findViewById() again. Also, I didn't find that I needed to know which EditText in the form had focus. I could just pick one arbitrarily and use it. Like so:

<pre><code> EditText myEditText= (EditText) findViewById(R.id.anyEditTextInForm); 
 InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
 imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);
</code></pre>

blocks|key|948499|text|此解决方案确保它隐藏键盘也不做任何事情，如果它没有打开。它使用扩展，因此可以在任何上下文所有者类中使用它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|948500|fun+Context.dismissKeyboard()+{

This Solution make sure that it hides keyboard also do nothing if it not opened.
It uses extension so it can be used from any Context Owner class. 

<pre><code>
fun Context.dismissKeyboard() {
 val imm by lazy { this.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager }
 val windowHeightMethod = InputMethodManager::class.java.getMethod("getInputMethodWindowVisibleHeight")
 val height = windowHeightMethod.invoke(imm) as Int
 if (height &gt; 0) {
 imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0)
 }
}


</code></pre>

blocks|key|948476|text|通过使用视图的上下文，我们可以使用Kotlin中的以下扩展方法来实现预期的结果：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|948477|/**
+*+Get+the+[InputMethodManager]+using+some+[Context].
+*/
fun+Context.getInputMethodManager():+InputMethodManager+{
++++if+(Build.VERSION.SDK_INT+>=+Build.VERSION_CODES.M)+{
++++++++return+getSystemService(InputMethodManager::class.java)
++++}

++++return+getSystemService(Context.INPUT_METHOD_SERVICE)+as+InputMethodManager
}

/**
+*+Dismiss+soft+input+(keyboard)+from+the+window+using+a+[View]+context.
+*/
fun+View.dismissKeyboard()+=+context
++++++++.getInputMethodManager()
++++++++.hideSoftInputFromWindow(
++++++++++++++++windowToken
++++++++++++++++,+0
++++++++)|code-block|syntax|javascript|948478|一旦这些都就位了，只需调用：|948479|editTextFoo.dismiss()|948480|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

By using the context of the view, we can achieve the desired outcome with the following extension methods in Kotlin:

<pre><code>/**
 * Get the [InputMethodManager] using some [Context].
 */
fun Context.getInputMethodManager(): InputMethodManager {
 if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.M) {
 return getSystemService(InputMethodManager::class.java)
 }

 return getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
}

/**
 * Dismiss soft input (keyboard) from the window using a [View] context.
 */
fun View.dismissKeyboard() = context
 .getInputMethodManager()
 .hideSoftInputFromWindow(
 windowToken
 , 0
 )
</code></pre>

Once these are in place, just call:

<pre><code>editTextFoo.dismiss()
</code></pre>
