title: How to remain at a scroll position in RecyclerView after adding items at its first index?
body: <p>I am using a RecyclerView in my app, appending more items to a <code>RecyclerView</code> after its last item makes the RecyclerView's scroll remain at its position but when I add items before the first item, the scroll position moves up to the newly first item added. How can I maintain my scroll position after adding new items at its first index?</p>
