最近在联系开发DaysMatter时遇到一个问题:
app中使用ListView来展示所有事件,每次添加完事件后使用下面代码来更新ListView.
toDoListView.refreshDrawableState();
会出现如下错误,错误内容是讲ListView的adapter必须是在UI线程中修改,不能在后台线程中修改
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(2131034172, class android.widget.ListView)
with Adapter(class android.widget.SimpleAdapter)]
在SO上看到一个类似的问题(http://*.com/questions/9771017/the-content-of-the-adapter-has-changed-but-listview-did-not-receive-a-notificati), 解决方法:
runOnUiThread(new Runnable() {
public void run() {
mAllResultsItem.add(item);
mAllResultsAdapter.notifyDataSetChanged();
}
});
