title: Set contentInset in RecyclerView
body: <p>I'm trying to implement a <code>RecyclerView</code> like a <code>UICollectionView</code> in iOS.
  I want to set a <code>contentInset</code> at the bottom of the recycler view but I can't find an option to do it.</p>
  
  <p>Is there something similar for Android?</p>
