解決The content of the adapter has changed but ListView did not receive a notification

問題分析：

log的資訊很簡單，就是在改動ListView内容後，沒有調用notifyDataSetChanged函數來更新，才導緻的異常。

- ::: E/AndroidRuntime(): java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. [in ListView(, class com.handmark.pulltorefresh.library.PullToRefreshListView$b) with Adapter(class android.widget.HeaderViewListAdapter)]

解決方法：

1.首先保證不線上程中調用notifyDataSetChanged函數。

2.在每次涉及到修改ListView内容時，一定要調用notifyDataSetChanged即可。
