如果你想听听这个来自活动在前景中，使用的onkeydown（）和留意键code_MEDIA_PLAY_PAUSE 。

If you are trying to listen for this from an activity in the foreground, use onKeyDown() and watch for KEYCODE_MEDIA_PLAY_PAUSE.

使用一个的BroadcastReceiver 为 ACTION_MEDIA_BUTTON 如果你想监听此事件的背景（例如，服务播放音乐）。

Use a BroadcastReceiver for ACTION_MEDIA_BUTTON if you are trying to listen for this event from the background (e.g., a service playing music).
