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:

Android Studio Shortcuts (Mac)

Notes:

Two of the most useful shortcuts utilize the Fn (function) keys. It is therefore recommended that you enable the "Use all F1, F2, etc. keys as standard function keys" option [System Preferences > Keyboard].
Be sure to enable the Mac OS X 10.5+ keymap in Android Studio [Preferences > Keymap].
A fairly complete shortcut list can be found here.

Useful symbols:

RecyclerView item onClick

RecyclerView does not have an OnItemClickListener like it's predecessor, ListView. However, detecting item clicks is pretty simple.

Set an OnClickListener in your ViewHolder creation:

private class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>  {

    public static class ViewHolder extends RecyclerView.ViewHolder
