是否有可用于从应用程序按钮静音全局声音的方法？

Is there a method that can be used to mute the global sound from an application button?

推荐答案

他们把它复杂得多，它必须是。你可以使用AudioManager.setStreamMute().随意使用下面的code。

They make it more complicated than it has to be. You can just use AudioManager.setStreamMute(). Feel free to use the code below.

//mute audio
AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
             amanager.setStreamMute(AudioManager.STREAM_NOTIFICATION, true);
             amanager.setStreamMute(AudioManager.STREAM_ALARM, true);
             amanager.setStreamMute(AudioManager.STREAM_MUSIC, true);
             amanager.setStreamMute(AudioManager.STREAM_RING, true);
             amanager.setStreamMute(AudioManager.STREAM_SYSTEM, true);


//unmute audio
AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
             amanager.setStreamMute(AudioManager.STREAM_NOTIFICATION, false);
             amanager.setStreamMute(AudioManager.STREAM_ALARM, false);
             amanager.setStreamMute(AudioManager.STREAM_MUSIC, false);
             amanager.setStreamMute(AudioManager.STREAM_RING, false);
             amanager.setStreamMute(AudioManager.STREAM_SYSTEM, false);
