com.androidpi.literefresh.behavior.RefreshContentBehavior<V>

All Implemented Interfaces:

android.os.Handler.Callback, Loader, RefreshController, Refresher

public class RefreshContentBehavior<V extends android.view.View>
extends ScrollingContentBehavior<V>
implements Refresher, Loader

This class is what we use to attach to an nested scrolling view, add new scrolling features to it.

This behavior is the pivot of header and footer behavior, without it the other behaviors can not work. All the offset and state changes come from it, so it can be used standalone.

For now, the nested scrolling view supported by CoordinatorLayout are android.support.v4.widget.NestedScrollView, android.support.v7.widget.RecyclerView which implement android.support.v4.view.NestedScrollingChild.

Use other parent view to wrap these scrollable child is OK, cause the ViewGroup and View already implement the nested scrolling event dispatch contract, but the nested scrolling child itself must exist in the view hierarchy.

The view to which this behavior is attached must be a direct child of CoordinatorLayout.
