Использую в двух активити своего проекта библиотеку
PullToRefresh. Да, сейчас библиотека уже объявлена как deprecated, но тем не менее, она крайне удобна и умеет обновлять, как сверху, так и снизу. Тем не менее, есть и проблема — изредка приложение вылетает со следующим логом:
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(16908298, class com.handmark.pulltorefresh.library.PullToRefreshListView$InternalListViewSDK9) with Adapter(class android.widget.HeaderViewListAdapter)]

Изредка настолько, что лично я это видел только один раз за много месяцев частого использования приложения. Но тем не менее периодически и пользователи присылают отчеты с этим логом.
Насколько я понимаю, это ошибка происходит не в моем коде, а в коде библиотеки, в частности в классе InternalListViewSDK9. Вот его код:
@TargetApi(9)
final class InternalListViewSDK9 extends InternalListView {
public InternalListViewSDK9(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected boolean overScrollBy(int deltaX, int deltaY, int scrollX, int scrollY, int scrollRangeX,
int scrollRangeY, int maxOverScrollX, int maxOverScrollY, boolean isTouchEvent) {
final boolean returnValue = super.overScrollBy(deltaX, deltaY, scrollX, scrollY, scrollRangeX,
scrollRangeY, maxOverScrollX, maxOverScrollY, isTouchEvent);
// Does all of the hard work...
OverscrollHelper.overScrollBy(PullToRefreshListView.this, deltaY, scrollY, isTouchEvent);
return returnValue;
}
}
Как можно устранить эту проблему, если даже нет возможности гарантированно ее воспроизвести? Может быть ее можно хотя бы как-то подавить, чтобы приложение не вылетало?
Простой
