如何从firebase中检索多个数据到android中的List View？

public class CustomAdapter extends BaseAdapter {
    private List<DataModel> dataList;
    private Context context;

    public CustomAdapter(Context context, List<DataModel> dataList) {
        this.context = context;
        this.dataList = dataList;
    }

    @Override
    public int getCount() {
        return dataList.size();
    }

    @Override
    public Object getItem(int position) {
        return dataList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            LayoutInflater inflater = LayoutInflater.from(context);
            convertView = inflater.inflate(R.layout.list_item, parent, false);
        }

        TextView textView = convertView.findViewById(R.id.textView);
        DataModel data = dataList.get(position);
        textView.setText(data.getName());

        return convertView;
    }
}

// 在Activity或Fragment中使用适配器
public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private CustomAdapter adapter;
    private DatabaseReference databaseRef;

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

        listView = findViewById(R.id.listView);
        List<DataModel> dataList = new ArrayList<>();
        adapter = new CustomAdapter(this, dataList);
        listView.setAdapter(adapter);

        // 获取Firebase数据库引用
        databaseRef = FirebaseDatabase.getInstance().getReference().child("节点名称");

        // 监听数据节点的变化
        databaseRef.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                dataList.clear();
                for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
                    // 将数据转换为数据模型对象
                    DataModel data = snapshot.getValue(DataModel.class);
                    dataList.add(data);
                }
                adapter.notifyDataSetChanged();
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {
                // 处理取消监听的情况
            }
        });
    }
}
