OnScrollChangeListener

Kotlin |Java

interface 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.
