安卓：保持活动的屏幕方向升级过程中的MediaPlayer运行 [英] Android: Keep MediaPlayer running during Activity screen orientation update

问题描述

我用的MediaPlayer播放的MP3。通过使用目前我禁用屏幕方向变化

I use a MediaPlayer to play an MP3. Currently I disabled screen orientation changes by using

android:screenOrientation="portrait"
android:configChanges="keyboardHidden|orientation"

在清单中。我想现在支持横向模式 - 即删除了这些标签 - 但问题是，破坏/创建周期内的球员被停止，然后重新启动。这是正常的，我真正做到这一点，即使在手动的onPause（）停止播放时，活动进入后台。

in the manifest. I do want to support landscape mode now - i.e. removed those tags - but have the problem that during the destroy/create cycle the player gets stopped and then restarted. This is okay and I actually do this even manually in onPause() to stop the player when the activity goes in the background.

要保持它在运行过程中的方向现在改变，我试图使其静态的（和使用应用程序上下文一次创建它）。当然，当我删除的onPause的 player.stop（）（）现在，它确实是我想要的 - 好了，，直到的活动进入后台。

To keep it running during orientation changes now, I tried making it static (and using the Application Context to create it once). Of course, when I remove the player.stop() in onPause() now, it does what I want - well, until the Activity goes in the background.

于是，两个问题：

• 如何确定活动将被调用后直接重新创建的onStop（）
• 或者：我怎样才能在该周期保持的MediaPlayer 运行，但停止时，应用程序进入后台

• How can I determine if the Activity will be recreated directly after the call to onStop()
• Or: How can I keep the MediaPlayer running during that cycle, yet stop it when the App goes in the background?

推荐答案

你看使用<一个href="http://developer.android.com/reference/android/app/Activity.html#onConfigurationChanged%28android.content.res.Configuration%29"相对=nofollow> onConfigurationChanged（）回调来处理一些这种逻辑？

Have you looked at using the onConfigurationChanged() callback to handle some of this logic?
