Animated Stroke. The google I/O website this year (https://google.com/io) has some funky animated lettering. I especially liked the animated stroke around the letters and wondered how you might implement that on Android. Turns out that AnimatedVectorDrawable makes this very easy! Here's how it looks: https://twitter.com/crafty/status/71077957997…

A SimpleSectionedRecyclerViewAdapter: use this class to realize a simple sectioned `RecyclerView.Adapter`.

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
