持续更新RecyclerView上的firebase数据

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private DatabaseReference databaseReference;
    private List<Data> dataList;

    public MyAdapter(DatabaseReference databaseReference) {
        this.databaseReference = databaseReference;
        dataList = new ArrayList<>();
        databaseReference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot snapshot) {
                dataList.clear();
                for (DataSnapshot dataSnapshot : snapshot.getChildren()) {
                    Data data = dataSnapshot.getValue(Data.class);
                    dataList.add(data);
                }
                notifyDataSetChanged();
            }

            @Override
            public void onCancelled(@NonNull DatabaseError error) {
                // 处理取消监听时的操作
            }
        });
    }

    // 其他必要的方法，例如 onCreateViewHolder() 和 onBindViewHolder()

    static class ViewHolder extends RecyclerView.ViewHolder {
        // ViewHolder的实现
    }
}
