在片段中未调用baseadapter的getview()方法

public class MyAdapter extends BaseAdapter {
    private List<String> data;

    public MyAdapter(List<String> data) {
        this.data = data;
    }

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

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

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // 获取当前列表项的数据
        String item = data.get(position);

        // 创建自定义的列表项视图
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);

        // 绑定数据到视图上
        TextView textView = itemView.findViewById(R.id.text_view);
        textView.setText(item);

        return itemView;
    }
}

public class MyFragment extends Fragment {
    private ListView listView;
    private MyAdapter adapter;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_layout, container, false);

        // 创建适配器并设置数据源
        List<String> data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");
        adapter = new MyAdapter(data);

        // 获取ListView控件并设置适配器
        listView = view.findViewById(R.id.list_view);
        listView.setAdapter(adapter);

        return view;
