Known direct subclasses LeanbackViewPager LeanbackViewPager A viewpager with touch and key event handling disabled by default.

---

Layout manager that allows the user to flip left and right through pages of data. You supply an implementation of a PagerAdapter to generate the pages that the view shows.

ViewPager is most often used in conjunction with Fragment, which is a convenient way to supply and manage the lifecycle of each page. There are standard adapters implemented for using fragments with the ViewPager, which cover the most common use cases. These are FragmentPagerAdapter and FragmentStatePagerAdapter; each of these classes have simple code showing how to build a full user interface with them.

Views which are annotated with the ViewPager.DecorView annotation are treated as part of the view pagers 'decor'. Each decor view's position can be controlled via its android:layout_gravity attribute. For example:

 <androidx.viewpager.widget.ViewPager
     android:layout_width="match_parent"
     android:layout_height="match_parent">

     <androidx.viewpager.widget.PagerTitleStrip
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_gravity="top" />

 </androidx.viewpager.widget.ViewPager>

You can find examples of using ViewPager in the API 4+ Support Demos and API 13+ Support Demos sample code.
