Scrolling recyclerview from the middle item

Question

I am developing app for Android TV and I have a vertical RecyclerView, when I scroll the RecyclerView using the DPAD control the RecyclerView scroll down when I get to the last viewable item and then it scroll.

Is there away that the focused item will always stay in the center of the recyclerview while I scroll using the DPAD and only when I get to the last item of the recyclerview the focus will go until the last item.

It seems simple enough to have a build in option inside the RecyclerView but I can't find an answer!!!

Thanks!

you can put one layout(view) before RecyclerView in a required position make the view visible with the selected item displayed. I think there is no way to freeze certain cell and scroll in recycler view. :) — iamnaran, Jul 29 '19 at 08:49

You can use SnapHelper which can snap the item either vertically or horizontally. For example: attach the instance the the recyclerView like this:

LinearSnapHelper snapHelper  = new LinearSnapHelper();
snapHelper.attachToRecyclerView(recyclerView);
