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

listview在適配數據時，滾動listview的時候會報錯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. [in ListView(2131230914, class android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]

經研究是adapter在handler裏面多次創建對象導致，解決方法：

1、在handler裏面判斷adapter，如果爲null，創建一次，之後就不再創建

2、在oncreate裏面創建adapter，並適配給listview，數據爲0，在handler裏面只是notifyDataSetChanged()
