android.support.v4.view

Support android.util classes to assist with development of applications for android API level 4 or later. The main features here are a variety of classes for handling backwards compatibility with views (for example MotionEventCompat allows retrieving multi-touch data if available), and a new ViewPager widget (which at some point should be moved over to the widget package).

Annotations

ViewPager.DecorView

Annotation which allows marking of views to be decoration views when added to a view pager.

Interfaces

ActionProvider.VisibilityListener	Listens to changes in visibility as reported by refreshVisibility().
AsyncLayoutInflater.OnInflateFinishedListener
LayoutInflaterFactory	Used with LayoutInflaterCompat.setFactory().
MenuItemCompat.OnActionExpandListener	Interface definition for a callback to be invoked when a menu item marked with SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW is expanded or collapsed.
NestedScrollingChild	This interface should be implemented by View subclasses that wish to support dispatching nested scrolling operations to a cooperating parent ViewGroup.
NestedScrollingParent	This interface should be implemented by ViewGroup subclasses that wish to support scrolling operations delegated by a nested child view.
OnApplyWindowInsetsListener	Listener for applying window insets on a view in a custom way.
ScrollingView	An interface that can be implemented by Views to provide scroll related APIs.
TintableBackgroundView	Interface which allows a View to receive background tinting calls from ViewCompat when running on API v20 devices or lower.
ViewPager.OnAdapterChangeListener	Callback interface for responding to adapter changes.
ViewPager.OnPageChangeListener	Callback interface for responding to changing state of the selected page.
ViewPager.PageTransformer	A PageTransformer is invoked whenever a visible/attached page is scrolled.
ViewPropertyAnimatorListener	An animation listener receives notifications from an animation.
ViewPropertyAnimatorUpdateListener	Implementors of this interface can add themselves as update listeners to an ViewPropertyAnimatorCompat instance to receive callbacks on every animation frame, after the current frame's values have been calculated for that ViewPropertyAnimatorCompat.
