推荐答案

Android将停止并重新启动您的活动，除非你告诉它，你会处理的方向改变自己。它这样做，这样你可以指定不同的资源（比如布局）是定位特定的（以及其他原因）。

Android will stop and restart your activity unless you've told it you will handle orientation changes yourself. It does this so that you can specify different resources (such as layouts) that are orientation-specific (among other reasons).

您需要添加<一个href="http://developer.android.com/guide/topics/manifest/activity-element.html#config">android:configChanges="orientation"为您的活动delcaration在AndroidManifest.xml中，你需要重写<一个href="http://developer.android.com/reference/android/app/Activity.html#onConfigurationChanged%28android.content.res.Configuration%29">onConfigurationChanged().我不相信你需要做什么特别的事情里面onConfigurationChanged（），简单地实现它应该做的伎俩。

You need to add android:configChanges="orientation" to your activity delcaration in your AndroidManifest.xml, and you need to override onConfigurationChanged(). I don't believe you need to do anything special inside onConfigurationChanged(), simply implementing it should do the trick.
