I have a ViewPager as an item in a Linear Layout, with each item in the view pager containing a RecyclerView. The problem is, whenever the page initially loads, or when I change pages on the ViewPager, the view automatically scrolls so the beginning of the recycler view is the top of the screen, rather than staying how it is.
