*** ** * ** ***
RecycledViewPool lets you share Views between multiple RecyclerViews.
If you want to recycle views across RecyclerViews, create an instance of RecycledViewPool and use[setRecycledViewPool(RecycledViewPool)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#setRecycledViewPool(android.support.v7.widget.RecyclerView.RecycledViewPool)).
RecyclerView automatically creates a pool for itself if you don't provide one.
