You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.

The RecyclerView should use a LinearLayoutManager. You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

This is a porting of the class SimpleSectionedListAdapter provided by Google

Example:

kevinvanmierlo

public class BaseActivity extends AppCompatActivity 
{
	public DrawerLayout drawerLayout;
    public ListView drawerList;
    private ActionBarDrawerToggle drawerToggle;
	
    protected void onCreate(Bundle savedInstanceState)
    {
    	// R.id.drawer_layout should be in every activity with exactly the same id.
    	drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
