title: Can CollapsingToolbarLayout fit the image height?
body: <p>Is it possible to set the height of <code>CollapsingToolbarLayout</code> or <code>AppBarLayout</code> when the image is already loaded? Similar to Whatsapp behaviour.</p>
  
  <p>Whatpsapp behaviour (Conversation Info Activity):
  The <code>AppBarLayout</code> height containing the <code>CollapsingToolbarLayout</code> is set on activity creation to a fixed value. But, when the group image is loaded, you can scroll to see the image on full height.</p>
  
  <p><strong>Edit</strong>: The target is fitting the <code>CollapsingToolbarLayout</code> with the image, getting the same proportion, and avoiding image crop.</p>
