We have a similar problem. We have a vertical RecyclerView. Each item of this vertical RecyclerView contains an horizontal RecyclerView, like in the Android TV app.
When we upgraded the support libs from 23.4.0 to 24.0.0 the automatic scroll suddenly appeared. In particular, when we open an Activity and we then go back, the vertical RecyclerView scrolls up so that the current horizontal RecyclerView row does not get cut and the row is displayed completely.
There is an easy fix. Add this to your outer/parent RecyclerView:
android:descendantFocusability="blocksDescendants"
I’ve found the solution in this questions:
- nested scrollview + recyclerview, strange autoscroll behaviour
- Android prevent nested recyclerview from automatically repositioning
Additionally, I’ve found another solution, which also works. In our case the vertical RecyclerView is contained inside a FrameLayout. If I add android:focusableInTouchMode="true" to this FrameLayout, the problem goes away.
By the way, there is also an open issue on the AOSP.
