title: How to add a fast-scroller to the RecyclerView
body: <h2>Background</h2>
  
  <p>On ListView, you could have a fast scroller which allowed you to drag a scrollbar to easily scroll to wherever you wished (using <a href="http://developer.android.com/reference/android/widget/AbsListView.html#attr_android:fastScrollEnabled" rel="noreferrer"><strong>fastScrollEnabled</strong></a> attribute)</p>
  
  <p>Together with "<a href="http://developer.android.com/reference/android/widget/SectionIndexer.html" rel="noreferrer"><strong>SectionIndexer</strong></a>" class and optionally some attributes, you could have a nice popup that shows as you use this scrollbar (link <a href="http://androidopentutorials.com/android-listview-fastscroll/" rel="noreferrer"><strong>here</strong></a>).</p>
  
  <p>Such a thing is shown on the contacts app so that you could scroll easily to specific letters.</p>
  
  <h2>The problem</h2>
  
  <p>RecyclerView doesn't seem to have any of those. Not even a fast-scroll.</p>
  
  <h2>The question</h2>
  
  <p>How do I add a fast scroller functionality for the RecyclerView?</p>
