title: ViewGroup finish inflate event
body: <p>I have created a custom layout which extends ViewGroup. Everything is working fine and I am getting the layout as expected.</p>
  
  <p>I want to dynamically change an element in the layout. However this is not working as I am calling it in onCreate and till that time the entire layout is not actually (drawn) inflated onto the screen and hence do not have actual size.</p>
  
  <p>Is there any event which can be used to find out when the inflation of the layout is done? I tried onFinishInflate but that would not work as Viewgroup has multiple views and this would be called multiple times.</p>
  
  <p>I am thinking of creating an interface in the Custom layout class but not sure when to fire it?</p>
