# android.support.v4.view added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) # android.support.v4.view | This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ## Annotations |------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------| | [ViewPager.DecorView](https://developer.android.com/reference/android/support/v4/view/ViewPager.DecorView) | Annotation which allows marking of views to be decoration views when added to a view pager. | ## Interfaces |----------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [ActionProvider.VisibilityListener](https://developer.android.com/reference/android/support/v4/view/ActionProvider.VisibilityListener) | Listens to changes in visibility as reported by[refreshVisibility()](https://developer.android.com/reference/android/support/v4/view/ActionProvider#refreshVisibility()). | | [AsyncLayoutInflater.OnInflateFinishedListener](https://developer.android.com/reference/android/support/v4/view/AsyncLayoutInflater.OnInflateFinishedListener) | | | [LayoutInflaterFactory](https://developer.android.com/reference/android/support/v4/view/LayoutInflaterFactory) | *This interface was deprecated in API level 26.1.0.
