问题 Edit I realized the issue was not solved, so I added the stack trace. This error occurs during Fragment transaction from an Activity. I read solutions for previous issues but couldn't find a relevant case. The transaction is done through a callback method from an Adapter. I'm doing it this way for the first time, so maybe something is off there. I can add the callback code if it's relevant. The final stack trace (the part that's paited red) E/AndroidRuntime: FATAL EXCEPTION: main Process: com

问题 I"m retrieving Firebase RealTime Database to my Recycleview Adapter Class . I want to sort the data by date with latest post at top.

Here is my Code rv.setHasFixedSize(true); LinearLayoutManager llm = new LinearLayoutManager(this); llm.setReverseLayout(true); rv.setLayoutManager(llm); llm.scrollToPositionWithOffset(0, 0); rv

问题 I am using RecyclerView in my android project and its performance has been really awful. From the answers here, I tried adding adapter.setHasStableIds(true); to my code. When running, I got an error: java.lang.IllegalStateException: Cannot change whether this adapter has stable IDs while the adapter has registered observers.

问题 Background: I am implementing pagination logic with RecyclerView by adding addOnScrollListener function. Problem faced: The onScrolled method is called once when the RecyclerView adapter is loaded with dy value of 0. However when the list reaches its end when scrolled, the onScrolled method is not triggered while the onScrollStateChanged is triggered correctly. Here is my Adapter: HistoryAdapter(Context context, ArrayList<HistoryItem> items, RecyclerView recyclerView) { inflater =
