For now I wrote a RecyclerView.Adapter on which I can display the same CardView multiple times with different content - analog to the ListView with a BaseAdapter . Now I'd like to write a RecyclerView with different CardView-Layout 's (in style of Google Now). I've already searched for tutorials but didn't found anything useful about that topic.
