Re: [android-developers] No data shown in my Recyclerview

2016-12-02 Thread Marina Cuello 
Hi! Are you calling recyclerView.setLayoutManager(somelayout) somewhere
outside the code you pasted?

"In contrast to other adapter-backed views such as ListView
 or
GridView
,
RecyclerView allows client code to provide custom layout arrangements for
child views. These arrangements are controlled by the
RecyclerView.LayoutManager
.
A LayoutManager must be provided for RecyclerView to function."
