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
