View.OnScrollChangeListener
| android.view.View.OnScrollChangeListener |
Interface definition for a callback to be invoked when the scroll X or Y positions of a view change.
Note: Some views handle scrolling independently from View and may
have their own separate listeners for scroll-type events. For example,
ListView allows clients to register an
AbsListView.OnScrollListener
to listen for changes in list scroll position.
