RecyclerView.RecycledViewPool


public 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.
