Important Notes

  • Remember to set android:id for me.henrytao.smoothappbarlayout.SmoothAppBarLayout in layout file so that it can call onSaveInstanceState and onRestoreInstanceState correctly. Otherwise, it won't work correctly with onOrientationChanged.
  • Remember to set android:minHeight for me.henrytao.smoothappbarlayout.SmoothAppBarLayout in layout file if you use ViewPager.
  • clipToPadding in RecyclerView won't work. You have to set HeaderHolder in apdater and it has to be placed at index 0.

Usage

Super easy! Just need to do 3 steps:

  • Change android.support.design.widget.AppBarLayout to me.henrytao.smoothappbarlayout.SmoothAppBarLayout and set android:id
  • Remove app:layout_behavior="@string/appbar_scrolling_view_behavior".
  • Add header to your NestedScrollView or RecyclerView.
