ListView:The content of the adapter has changed but ListView did not receive a notification终极解决方法
使用ListView时遇到如下的异常信息:
10-26 18:30:45.085: E/AndroidRuntime(7323): 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(2131296280, class android.widget.ListView) with Adapter(class com.souapp.appmanager.ApkListAdapter)]
其实我在listview的adapter添加完数据后,使用了handler去调用datper.notifyDataSetChanged();来通知listview显示变化结果;
虽然自己很确定没有多线程操作,但是有人说listview本来就是线程不安全的,这个不关心了,看了国外一个开发者的方法很简单。
解决方法1:
ListView.requestLayout();
Adatper.notifyDataSetChanged();
在你adpater更新前,调用listview的requestLayout(),这样做无非就是弥补数据数量不一致导致报错,虽然一个解决的好办法。
但是实际上用的时候我发现也会出问题,想了想最彻底的解决办法
彻底解决方法:
把 listview的adapter数据更新和dapter.notifyDataSetChanged()方法的调用必须同时放到单独一个线程里,报错基本是都是这个原因,有人把adapter里的数据更新了,但是 dapter.notifyDataSetChanged() 放到一个单独线程去更新,结果出现notifyDataSetChanged更新同步的问题

这个问题也不是必崩溃,低版本崩的多,高版本好像崩溃得少
