无法将数据从GoogleMap中的ListView适配器类显示到列表中

// 自定义适配器类
public class MyAdapter extends BaseAdapter {
    private List<String> dataList;
    private LayoutInflater inflater;

    public MyAdapter(Context context, List<String> dataList) {
        this.dataList = dataList;
        inflater = LayoutInflater.from(context);
    }

    @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) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.list_item_layout, parent, false);
            holder = new ViewHolder();
            holder.textView = convertView.findViewById(R.id.text_view);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        // 填充数据到视图控件
        String data = dataList.get(position);
        holder.textView.setText(data);

        return convertView;
    }

    static class ViewHolder {
        TextView textView;
    }
}

// 在GoogleMap的Activity或Fragment中使用适配器
public class GoogleMapActivity extends AppCompatActivity {
    private ListView listView;
    private MyAdapter adapter;
    private List<String> dataList;

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

        // 初始化数据源
        dataList = new ArrayList<>();
        dataList.add("Item 1");
        dataList.add("Item 2");
        dataList.add("Item 3");

        // 实例化ListView和适配器
        listView = findViewById(R.id.list_view);
        adapter = new MyAdapter(this, dataList);

        // 设置适配器
        listView.setAdapter(adapter);
    }
}
