【遇见Android bug】The content of the adapter has changed but ListView did not receive a notification

bug日志如下:
The content of the adapter has changed but ListView did not receive a notification
遇到这个问题的情境是在AsyncTask的doInBackground中对数据集执行了clear()操作。而在onPostExecuter中执行了mAdapter.notifyDataSetChanged()动作。
为了避免出现此问题,撸代码时应该尽量避免在后台线程中操作数据集,如上的clear()操作等。建议在AsyncTask执行前处理数据集的清空和重置操作,或者在onPostExecuter()方法中执行数据集的清空和重置操作。
