问题 I am experimenting with integrating a Firebase-backed RecyclerView in a React Native app. With hardcoded data it works well, but upon inserting rows loaded dynamically and calling either notifyItemInserted() or notifyDataSetChanged() on the RecyclerView.Adapter, the RecyclerView itself does not reflect the change. This manifests as an initial blank view until the app's refresh button is tapped, which has the sole effect of re-rendering the RecyclerView from the React Native side, or until

问题 I have a RecyclerView and each row has a EditText also. I am adding item to RecyclerView by searching them and then I type the quantity in the edit text. Then I send it to the server to store using json format. Item add is working perfectly. There is no edit text value swapping problem also when scrolling. I can display 5 rows in the screen. Problem is when I send item to the server, edit text values in bottom rows get the same after 5th row. These are the rows I am adding to the recyclerview

问题 I'm playing around with the StaggeredGridLayoutManager and have something close to what I want. I have a horizontal staggered grid with 2 rows, where some items are the height of 1 row, and others span both rows. I want the single row height items to stack up and I thought that could be achieved by setting the gap strategy to GAP_HANDLING_MOVE_ITEMS_BETWEEN_SPANS, but this does not appear to work. Current: ___ ___ ___ ___ |___| | | |___| | | | | | | |___| |___| What I want: ___ ___ ___ |___|

问题 This question already has answers here : recyclerview No adapter attached; skipping layout (30 answers) Closed 3 years ago . I'm getting this error but I don't know what is causing it...perhaps something to do with the fact that this is being initialized in a fragment and not in the activity itself. Edit: included StatsAdapter code public class StatsFragment extends Fragment { private RecyclerView mRecyclerView; private LinearLayoutManager mLinearLayoutManager; private RecyclerView.Adapter
