All Implemented Interfaces:

android.os.Handler.Callback, RefreshController, Refresher

public class RefreshHeaderBehavior<V extends android.view.View>
extends VerticalIndicatorBehavior<V,HeaderBehaviorController>
implements Refresher

This class is used to attach to a header view and add nested scrolling features to it. Note that this behavior can not work standalone, the header view to which this behavior is attached must work with a nested scrolling content view that is attached with an RefreshContentBehavior, otherwise it'll not work. The view to which this behavior is attached must be a direct child of CoordinatorLayout.
