Найти точную координату вида на экране Android

Question

Кажется очень простым, но почему-то я не могу понять, как найти координату слева (x) и top (y). Я пробовал почти каждый ответ, каждый дает нуль.

Вот XML

**Code snippet to find out co-ordinate** 
private void showUseSearch() { 

    View etSearchTextList = findViewById(R.id.et_inputSearch); 
    int[] tableLayoutCorners = new int[2]; 

    Rect myViewRect = new Rect(); 
    etSearchTextList.getGlobalVisibleRect(myViewRect); 
    float x = myViewRect.left; 
    float y = myViewRect.top; 

    etSearchTextList.getLocationInWindow(tableLayoutCorners); 

    Log.i(TAG, x+","+y+"-"+tableLayoutCorners[0] + "-" + tableLayoutCorners[1] + ",showUseSearch: " + etSearchTextList.getX() + "," + etSearchTextList.getY() + "-" + etSearchTextList.getPivotX() + "-" + etSearchTextList.getPivotY()); 
    }

Если вы будете пытаться получить позицию до полного рендеринга пользовательского интерфейса вам ш плохо получишь его. Вы можете использовать прослушиватель treeObserver, чтобы получить x и y после привязки к пользовательскому интерфейсу. здесь вы идете:

view.getViewTreeObserver().addOnGlobalLayoutListener(
    new ViewTreeObserver.OnGlobalLayoutListener() { 
     @Override 
     public void onGlobalLayout() { 
      // Layout has happened here. 
      int x = (int)view.getX();// returns float 
      int y = (int)view.getY(); 

      // Don't forget to remove your listener when you are done with it. 
      view.getViewTreeObserver().removeOnGlobalLayoutListener(this); 
     } 
    });
