android NestedScrollView里嵌套Recyc

布局

<androidx.core.widget.NestedScrollView
   android:id="@+id/scroView"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   app:layout_anchorGravity="bottom"
   app:layout_behavior="@string/appbar_scrolling_view_behavior">

   <androidx.recyclerview.widget.RecyclerView
           android:id="@+id/rvList"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:nestedScrollingEnabled="false"
            android:overScrollMode="never" />

</androidx.core.widget.NestedScrollView>

解决方案

scroView.fling(0)
scroView.smoothScrollTo(0,0)
