A Recycler is responsible for managing scrapped or detached item views for reuse.
A "scrapped" view is a view that is still attached to its parent RecyclerView but that has been marked for removal or reuse.
Typical use of a Recycler by a RecyclerView.LayoutManager will be to obtain views for
an adapter's data set representing the data at a given position or item ID.
If the view to be reused is considered "dirty" the adapter will be asked to rebind it.
If not, the view can be quickly reused by the LayoutManager with no further work.
Clean views that have not requested layout
may be repositioned by a LayoutManager without remeasurement.
