ViewPager2 is the replacement of ViewPager, addressing most of its predecessor's pain-points, including right-to-left layout support, vertical orientation and modifiable Fragment collections.

New features

  • Comparing to its predecessor android.support.v4.view.ViewPager (VP1):
  • Right-to-left (RTL) layout support
  • Vertical orientation support
  • notifyDataSetChanged fully functional (VP1 bugs addressed)

API changes

  • FragmentStateAdapter replaces FragmentStatePagerAdapter
  • RecyclerView.Adapter replaces PagerAdapter
  • registerOnPageChangeCallback replaces addPageChangeListener

Known issues

  • clipToPadding
  • no fakeDrag
  • JavaDoc
  • nested scrolling parallel to orientation
  • no offscreen limit control
  • needs better TabLayout integration
  • no pageWidth setter (forced 100%/100%)
  • page transformer: no hardware/software layer choice; no reverse drawing order
  • keep current item visible when inserting a page before current
  • keyboard navigation needs work
  • FragmentStateAdapter stability / performance improvements coming
