ViewActions to interact RecyclerView. RecyclerView works differently than
AdapterView. In fact, RecyclerView is not an AdapterView anymore, hence it can't be used
in combination with onData(Matcher).
To use ViewActions in this class use onView(Matcher) with a
Matcher that matches your RecyclerView, then perform a
ViewAction from this class.
