title: How to implement endless list with RecyclerView?
body: <p>I would like to change <code>ListView</code> to <a href="https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html"><code>RecyclerView</code></a>. I want to use the <code>onScroll</code> of the <a href="http://developer.android.com/reference/android/widget/AbsListView.OnScrollListener.html#onScroll"><code>OnScrollListener</code></a> in <code>RecyclerView</code> to determine if a user scrolled to the end of the list. </p>
  
  <p>How do I know if a user scrolls to the end of the list so that I can fetch new data from a REST service?</p>
