Port Recycler view created for mobile app to Android TV supporting Dpad controls

Question

I am currently trying to port Android mobile app to Android TV. I have a RecyclerView that seems to be displaying correctly in my Android TV app. But I don't seem to be able to navigate inside RecyclerView using dpad controls. P.S i have tried following line.Couldn't find anything else

        android:descendantFocusability="afterDescendants"

Also is it recommended to use recycler view for TV apps ?

Also i have read complete architecture of TV app at developer.android.com and also went through their sample project, But found recycler view nowhere.

I added this line android:descendantFocusability="afterDescendants" not working — Hussnain Azam, Jan 18 '17 at 12:37
also added android:focusable="true" to recylerview item. no luck — Hussnain Azam, Jan 30 '17 at 09:55

As @ULazdins stated, you may try to make your RecyclerView focusable. You may refer with this workaround for the bug with RecycleView focus scrolling when navigating with d-pad.

As I can see from source the issue is because GridLayoutManager uses LinearLayoutManager's implementation of onFocusSearchFailed() which is called when focus approaches the inner border of RecyclerView. LinearLayoutManager's implementation just offers first/last (depends on scrolling direction) element. Hence focus jumps to first/last element of new row.

Hope this helps!
