How to get height of a view in Kotlin?

1

I am trying to get height of a view in onCreate method but I couldn't find any way to remove OnGlobalLayoutListener.

In Java (working):

containerLayout.getViewTreeObserver.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {  

  @Override  

  public void onGlobalLayout() {  

  containerLayout.getViewTreeObserver().removeGlobalOnLayoutListener(this);

  int width  = layout.getMeasuredWidth();

  int height = layout.getMeasuredHeight();


  }  

});

In Kotlin (not excepting “this”):

containerLayout.viewTreeObserver.addOnGlobalLayoutListener {

  containerLayout.viewTreeObserver.removeOnGlobalLayoutListener(this)

  Toast.makeText(applicationContext, "size is "+ containerLayout.height,Toast.LENGTH_LONG).show()

}

Is there any reference or example for this problem? Thanks.
