title: Possible do define sections in RecyclerView in Android?
body: <p>In iOS <code>UITableView</code> could have 'sections' and inside a section 'rows'. Is this possible in Android with <code>RecycleView</code>?</p>
  
  <p><code>RecyclerView.Adapter</code> has only a <code>getItemCount()</code> delegate method. But nothing for sections. What alternatives you can suggest?</p>
  
  <p>I thought to put the section headers into a row, and melt the sections into one global section, and so no section will need. Any better idea?</p>
