RecyclerView.RecycledViewPool
class RecyclerView.RecycledViewPool
RecycledViewPool lets you share Views between multiple RecyclerViews.
If you want to recycle views across RecyclerViews, create an instance of RecycledViewPool and use setRecycledViewPool.
RecyclerView automatically creates a pool for itself if you don't provide one.
