问题 I have implemented a horizontal scrollable RecyclerView . My RecyclerView uses a LinearLayoutManager , and the problem I am facing is that when I try to use scrollToPosition(position) or smoothScrollToPosition(position) or from LinearLayoutManager 's scrollToPositionWithOffset(position) . Neither works for me. Either a scroll call doesn't scroll to the desired location or it doesn't invoke the OnScrollListener .

问题 I have a recyclerview in my android project which displays media contents within each view. What I'm trying to achieve is that I'm able to play/pause media as I scroll up and down.

In my activity fragment I have this: layoutmanager = new LinearLayoutManager(Activity); adapter = new FeedAdapter(vid, userName, this.Context); feeditem.SetLayoutManager(layoutmanager); feeditem.SetAdapter(adapter);

The problem with this solution is that the first and the last item will never be horizontally centered
