Initialize the view and call this method in on create method

 view.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() { 
    @SuppressLint("NewApi")
     @SuppressWarnings("deprecation") 
    @Override 
    public void onGlobalLayout() {
     //now we can retrieve the width and height 
    int width = view.getWidth(); 
    int height = view.getHeight(); 
    //... //do whatever you want with them //... //this is an important step not to keep receiving callbacks: //we should remove this listener //I use the function to remove it based on the api level!
     if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN)
     view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
     else
     view.getViewTreeObserver().removeGlobalOnLayoutListener(this); 
    } });
