适配器的内容已更改，但ListView未收到通知

此问题意味着basicAdapter尝试为listView调整的数据已更改，显然意味着

ItemDetailsRayList

不包含相同的数据

我想你在活动中操纵了这个列表

---

这是很正常的，您应该做的是，在使用适配器的活动的onResume回调中调用

适配器.notifyDataSetChanged（）

来通知适配器。

我认为问题在于您正在更新

适配器，它导致了您的异常

我想您需要确保只从UI线程使用UI元素进行操作。如果您使用的是AsyncTask，那么您需要调用

adapter.notifyDataSetChanged();

在
onProgressUpdate（）
或
onPostExecute（）
方法中，这是我得到的正确代码
