getViewTypeCount and getItemViewType methods of ArrayAdapter

Question

Can somebody in plain words explain me the usage of getViewTypeCount() and getItemViewType() methods of ArrayAdapter?

Answer 1

If we need to show different type of view in list-view then its good to use getViewTypeCount() and getItemViewType() in adapter instead of toggling a view View.GONE and View.VISIBLE can be very expensive task inside getView() which will affect the list scroll.

Please check this one for use of getViewTypeCount() and getItemViewType() in Adapter.
