Android RecyclerView Scroll Position and State Preservation
Pain Points (Public)
When navigating from an item to a detail screen and pressing the back button, the Android RecyclerView loses its scroll position and resets to the top, disrupting user browsing despite list data remaining intact in the ViewModel.
Suggested Approach (Public)
Persist the LinearLayoutManager scroll state as a Parcelable inside the ViewModel or SavedStateHandle, and set the RecyclerView.Adapter stateRestorationPolicy to PREVENT_WHEN_EMPTY to seamlessly restore the exact scroll offset upon back navigation.

Opportunity assessment PRO
Development brief PRO
- Sell the bounded outcome of Android RecyclerView Scroll Position and State Preservation, not a general service bundle: Mobile Android applications using LinearLayoutManager often lose exact list scroll offsets and adapter state when users navigate back from detail fragments. Implementing custom Parcelable state bundles or ViewModel scroll caches ensures seamless scroll restoration without jarring list jumps
- For Android RecyclerView Scroll Position and State Preservation, first capture the primary user, core action, required screens or states, platform constraints, and acceptance behavior in one reviewable intake record
