title: Android fragment transition on back navigation to previous fragment
body: <p>I have 2 fragments the first contains a button which on clicked opens a fragment with a <code>ListView</code> in it. I have a shared element transition for the button to transition into the new fragment (root layout) but I would also like to have this transition in reverse (the list fragment contracts into the button again).</p>
  
  <p>However currently I detect the list item click and send an event to the Activity which pops the listview fragment off the backstack (<code>popBackStackImmediate()</code>) hence does not show the transition.</p>
  
  <p>Is there a good way to allow back navigation while preserving reverse transition to work as well?</p>
