无法更新gridview android中列表中的文本视图

// 创建适配器
public class MyAdapter extends BaseAdapter {
    private List<String> data;
    private Context context;

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

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

        // 更新文本视图内容
        holder.textView.setText(data.get(position));

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

// 更新GridView中的文本视图
List<String> data = new ArrayList<>();
data.add("Item 1");
data.add("Item 2");
data.add("Item 3");

MyAdapter adapter = new MyAdapter(data, context);
gridView.setAdapter(adapter);

// 修改文本视图内容
String newText = "New Text";
data.set(position, newText);

// 通知适配器刷新视图
adapter.notifyDataSetChanged();
