title: Recyclerview not populating with data after orientation change
body: <p>I have a recyclerview having different layouts for portrait and landscape. When the activity starts, the recyclerview populates with data irrespective of the orientation. But if the orientation is changed then no data is shown. And no data is shown on consequent orientation changes. </p>

  <p>As can be seen, certain parts of the code are getting called repeatedly. I do not know why. OnCreateView is being called again after onViewCreated is called after orientation change. Probably this is causing the issue. Any help would be appreciated. Thanks.</p>
