How to get the Height of Android Keyboard?

Question

How get height of Android Keyboard?

I try:

KeyboardView keyboardView = new KeyboardView(_activity.getApplicationContext(), null);
Log.i("","xxx height " + keyboardCustom.mKeyboardView.getHeight());
            Log.i("","xxx height " + keyboardCustom.mKeyboardView.getBottom());

But always get 0.

Solution

Use OnGlobalLayoutListener for getting Keyboard height or implement above code snippet

• chatRootLayout is your xml root layout

• pass this rootLayout as parentLayout parameter in checkKeyboardHeight

   private void checkKeyboardHeight(final View parentLayout)
      {
        chatRootLayout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() 
        {
              @Override
              public void onGlobalLayout() 
              {
                      Rect r = new Rect();
  
                      chatRootLayout.getWindowVisibleDisplayFrame(r);
  
                      int screenHeight = chatRootLayout.getRootView().getHeight();
                      int keyboardHeight = screenHeight - (r.bottom);
  
                      if (previousHeightDiffrence - keyboardHeight > 50) 
                      {                           
                          // Do some stuff here
                      }
  
                      previousHeightDiffrence = keyboardHeight;
                      if (keyboardHeight> 100) 
                      {
                          isKeyBoardVisible = true;
                          changeKeyboardHeight(keyboardHeight);
                      } 
                      else
                      {
                          isKeyBoardVisible = false;
                      }
                  }
          });
  }
  

  Here is changeKeyboardHeight() method

  private void changeKeyboardHeight(int height) 
  {
      if (height > 100) 
      {
              keyboardHeight = height;
              LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, keyboardHeight);
              yourLayout.setLayoutParams(params);
      }
  }

I use parentLayout as _activity.getWindow().getDecorView() and chatRootLayout as EditTextEx. And never call addOnGlobalLayoutListener

[Shekhar Mangrule]

Call checkKeyboardHeight() method on your onCreate() and make sure that your parentLayout & chatRootLayout must be your xml root/main layout (whether it was Linear/Relative)..
