我有一个GridView，我有一个自定义适配器，它用自定义数据填充单元格，一些单元格有数据，其他单元格有列表。列表是动态创建的，并使用自定义列表适配器填充。
我希望在单击列表项后更新或刷新GridView内的所有内容，换句话说，更新/刷新需要在GridView的适配器内进行。
我该怎么做？
在点击了GridView内部列表中的某个项目后，我在适配器中使用了这个代码：
notifyDataSetChanged();
点击列表项后，应用程序崩溃了，我在错误日志中得到了这个：

该错误消息引用了我的getView方法中的这行代码：
Label = (TextView) convertView;
答案 0 :(得分：0)
只需调用适配器的notifyDataSetChanged方法即可。
答案 1 :(得分：0)
尝试访问textview，如下所示：
Label = (TextView) convertView.findViewByID(R.id.textview);
