Fragment
class BatchFragment : Fragment() { private val viewModel: BatchViewModel by viewModels() override fun onActivityCreated(savedInstanceState: Bundle?) { super.onActivityCreated(savedInstanceState) initList() } override fun onDestroyView() { super.onDestroyView() viewModel.listState = list.layoutManager?.onSaveInstanceState() // val layoutManager = list.layoutManager as GridLayoutManager // val position = layoutManager.findFirstVisibleItemPosition() } override fun initList() { adapter = LocalAdapter(viewModel) adapter.registerAdapterDataObserver(object : RecyclerView.AdapterDataObserver() { override fun onItemRangeInserted(positionStart: Int, itemCount: Int) { if (viewModel.listState != null) { list.layoutManager?.onRestoreInstanceState(viewModel.listState) // val layoutManager = list.layoutManager as GridLayoutManager // layoutManager.scrollToPositionWithOffset(position, 0) } } }) list.adapter = adapter // load items into adapter // adapter.submitList(...) } private class LocalAdapter(val viewModel: BatchViewModel) : ListAdapter<ViewItem, LocalAdapter.ViewHolder>(DiffCallback()) { // ... }}NOTE: I am using Jetpack Navigation, so I listen to onDestroyView to save state (when navigate to another fragment).
ViewModel
class BatchViewModel(application: Application) : AndroidViewModel(application) { var listState: Parcelable? = null}
