title: RecyclerView.Adapter and ImageView.getWidth()
body: <p>I have a recyclerview that display some element, in which may or not be a picture.
  For displaying that picture, for performance reasons I'm using <a href="http://developer.android.com/training/camera/photobasics.html#TaskScalePhoto" rel="nofollow">this</a> method.</p>
  
  <p>I'm using it inside <code>public void onViewAttachedToWindow(final ViewHolder holder)</code>, but I still get 0 as width and height of my ImageView.</p>
  
  <p>So, when should I display the image?</p>
