问题 I modified my code according to the answers I found to similar questions but none of them worked. I am using TabFragments and RecyclerViews. The console displays the error "E/RecyclerView: No adapter attached; skipping layout" four times.

问题 I have a horizontal recyclerView, When I first open the activity I want to make all the items in recyclerview scroll to the bottom (to the right in this case) and back to the top (to the left).
