Adapter
Returns the number of types of Views that will be created by
Adapter.getView(int, android.view.View, android.view.ViewGroup)
. Each type represents a set of views that can be
converted in Adapter.getView(int, android.view.View, android.view.ViewGroup)
. If the adapter always returns the same
type of View for all items, this method should return 1.
This method will only be called when the adapter is set on the AdapterView
.
