在Android中静音全局声音

Question

是否有一种方法可用于从应用程序按钮静音全局声音？

Answer 1

它们使它变得更加复杂.你可以使用AudioManager.setStreamMute().随意使用下面的代码.

//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);

提供的答案似乎是从Android M(API 23)中弃用的,因此这提供了另一种解决方案

public void MuteAudio(){
    AudioManager mAlramMAnager = (AudioManager) aActivity.getSystemService(aContext.AUDIO_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_NOTIFICATION, AudioManager.ADJUST_MUTE, 0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_ALARM, AudioManager.ADJUST_MUTE, 0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_MUTE, 0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_RING, AudioManager.ADJUST_MUTE, 0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_SYSTEM, AudioManager.ADJUST_MUTE, 0);
    } else {
        mAlramMAnager.setStreamMute(AudioManager.STREAM_NOTIFICATION, true);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_ALARM, true);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_MUSIC, true);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_RING, true);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_SYSTEM, true);
    }
}

public void UnMuteAudio(){
    AudioManager mAlramMAnager = (AudioManager) aActivity.getSystemService(aContext.AUDIO_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_NOTIFICATION, AudioManager.ADJUST_UNMUTE, 0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_ALARM, AudioManager.ADJUST_UNMUTE, 0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_UNMUTE,0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_RING, AudioManager.ADJUST_UNMUTE, 0);
        mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_SYSTEM, AudioManager.ADJUST_UNMUTE, 0);
    } else {
        mAlramMAnager.setStreamMute(AudioManager.STREAM_NOTIFICATION, false);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_ALARM, false);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_MUSIC, false);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_RING, false);
        mAlramMAnager.setStreamMute(AudioManager.STREAM_SYSTEM, false);
    }
}

Android中有四种声音设置:

• 报警
• 音乐
• 铃声
• 通知

首先,创建一个AudioManager类的对象:

AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);

如果要设置音量,请使用以下命令:

通知

amanager.setStreamVolume(AudioManager.STREAM_NOTIFICATION,
    AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);

用于报警

amanager.setStreamVolume(AudioManager.STREAM_ALARM,
    AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);

对于音乐

amanager.setStreamVolume(AudioManager.STREAM_MUSIC,
    AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);

对于铃声

amanager.setStreamVolume(AudioManager.STREAM_RING,
    AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);
