RecyclerView SnapHelper fails to show first/last items

Question

I have a RecyclerView which is attached to a LinearSnapHelper to snap to center item. When I scroll to the first or last items, these items are not ful

Answer 1

I know I am late but I want to suggest an simple solution written in Java code:

Create CustomSnapHelper class:

 public class CustomSnapHelper extends LinearSnapHelper {
        @Override
        public View findSnapView(RecyclerView.LayoutManager layoutManager) {
            if(layoutManager instanceof LinearLayoutManager){
                LinearLayoutManager linearLayoutManager = (LinearLayoutManager) layoutManager;
                if(needToDoSnap(linearLayoutManager)==false){
                    return null;
                }
            }
            return super.findSnapView(layoutManager);
        }
        public boolean needToDoSnap(LinearLayoutManager linearLayoutManager){
            return linearLayoutManager.findFirstCompletelyVisibleItemPosition()!=0&&linearLayoutManager.findLastCompletelyVisibleItemPosition()!=linearLayoutManager.getItemCount()-1;
        }
    }

Attach an object of CustomSnapHelper for recycler view:

CustomSnapHelper mSnapHelper = new CustomSnapHelper();
mSnapHelper.attachToRecyclerView(mRecyclerView);
