アプリケーションの 2 つのアクティビティで PullToRefresh ライブラリを使用しています。このライブラリは非推奨ですが、非常に便利で、上からだけでなく下からの更新も処理できます。しかし、問題があります: このログでアプリケーションがクラッシュすることはめったにありません:
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)]

このクラッシュはめったに発生しないため、デバイスを頻繁に使用する月に 1 回しか発生しません。しかし、Google Play デベロッパー コンソールのユーザーからのこのログにクラッシュ レポートが表示されます。
私が理解している限り、このクラッシュは私のコードではなく、InternalListViewSDK9 クラスの PullToRefresh ライブラリのコードで発生しています。InternalListViewSDK9 のコードは次のとおりです。
@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;
}
}
再現できないことを考慮して、このバグを修正するにはどうすればよいですか? それを抑えることは可能でしょうか？
