如何从firebase中的节点检索值并在回收器视图中显示？

// 适配器类
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private ArrayList<String> mData;

    public MyAdapter(ArrayList<String> data) {
        mData = data;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        String value = mData.get(position);
        holder.textView.setText(value);
    }

    @Override
    public int getItemCount() {
        return mData.size();
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TextView textView;

        public ViewHolder(View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.text_view);
        }
    }
}

// 活动或片段中的代码
public class MainActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private MyAdapter mAdapter;
    private DatabaseReference mDatabase;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRecyclerView = findViewById(R.id.recycler_view);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

        // 获取对Firebase数据库的引用
        mDatabase = FirebaseDatabase.getInstance().getReference();

        // 添加值事件监听器
        mDatabase.addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                ArrayList<String> data = new ArrayList<>();
                for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
                    String value = snapshot.getValue(String.class);
                    data.add(value);
                }

                // 创建适配器并设置给RecyclerView
                mAdapter = new MyAdapter(data);
                mRecyclerView.setAdapter(mAdapter);
                mAdapter.notifyDataSetChanged();
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {
                // 处理取消事件
            }
        });
    }
}
