What is the proper way to save the scroll position in an EpoxyRecyclerView?

When I use the back button to return to my Fragment (which is only a vertical EpoxyRecyclerView using MvRx) it starts at the top of the list instead of the screen. This is probably annoying for users who click on a photo, see the full screen image, and then end up at the top of the screen when hitting back. Is this something Android should be doing automatically? Should I be storing the scroll position in onSavedInstanceState? Or does Epoxy have some other solution?

I know that I can set saveViewState on Models, but I don’t see how this would help the RecyclerView resume at the previous scroll position.

I have the same problem ! I use carousel within a vertical RecyclerView+Navigation,but carousel not saved the position.

I am also having this exact same issue where nested recyclerview contains horizontal carousel and whenever I navigate to other page and back, the carousels position is not retained - I have overridden shouldSaveViewState and I have tried to initialize controller in onViewCreated and in onCreate without good results

This is indeed the case. I did the same thing. Although my original method kept the scroll position, the adapter leaked. Now if I use this, it is no problem to empty the adapter when I leave the window, but the original scroll state is gone. I don’t know how to solve it, maybe I can rewrite the navigation component to not destroy the view when navigating?Just overlay the view. This is the BaseEpoxyFragment I wrote while practicing.
