Question

我的ViewFlipper中有一个Activity，用作ListView的页脚视图。关于我在模拟器中看到的问题，我已经发布了一段时间。见Activity has leaked IntentReceiver android.widget.ViewFlipper。我找到了答案。

现在，我在设备上调试时遇到问题。基本上当设备配置更改（旋转）导致我的活动被破坏时，我会崩溃。见日志。

有趣的是，如果未附加调试器，则此问题不会经常发生。这让我很沮丧。

从我所看到的ViewFlipper::onDetachedFromWindow试图取消注册未注册的接收者。在ViewFlipper被调用之前，ListView已使用removeFooterView从ViewFlipper::onDetachedFromWindow中移除。

这是我用来从列表视图中删除viewFlipper的方法：

mLoadMoreFlipper.stopFlipping();
mLoadMoreFlipper.removeAllViews();
getExpandableListView().removeFooterView(mLoadMoreFlipper);
mLoadMoreFlipper = null;

还有其他方法强制销毁视图。我已经尝试了WindowManager.removeView但是会抛出一个例外the view has not been registered with WindowManager。

感谢任何帮助。

我和前几天有同样的问题。我找到了这个解决方案http://daniel-codes.blogspot.com/2010/05/viewflipper-receiver-not-registered.html，但我不明白如何使用它。所以，我从这里得到答案ViewFlipper : Receiver not registered，我的问题已经解决了。试试吧！我相信这个解决方案会对你有帮助。

Answer 2

在我的情况下，当viewFlipper运行动画时，在屏幕上重现此旋转。由于某些原因，onDetachedFromWindow()方法未在此viewFlipper上调用。

我已在m_viewFlipper.clearAnimation()方法中调用MyActivity.onPause()来解决此问题。

或者，可以扩展ViewFlipper类并覆盖onSaveInstanceState()方法，添加clearAnimation()次调用。
