在Android中静音全局声音

是否有一种方法可用于从应用程序按钮静音全局声音？

Android中有四种声音设置：

• 警报
• 音乐
• 铃声
• 通知

首先，创建

AudioManager

类的对象：

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

如果要设置卷，请使用以下选项：

通知 报警 为了音乐 手机铃声

---

从技术上讲，不存在全局卷。巴尔加夫的回答应该会让你走上正确的道路。AudioManager类可以控制许多不同的“流”，即音乐、振铃器、通话、报警、通知、系统和DMTF。您必须将所有这些单独流的体积设置为0，这是一个非常简单的过程，如图所示

只需创建Audiomanager对象：-

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

然后使用它更改所有流的卷：-

audioManager.setStreamVolume(AudioManager.Stream, Extra Flags or null);

不要键入AudioManager.Stream，而是键入“AudioManager.”，然后按Ctrl+空格键查看所有可以使用的不同流。检查文档中的许多不同类型的标志，这些标志可以在音量更改时添加声音或振动，或打开音量UI

---

每个流可能有不同的最大卷，因此确保使用getMaxStreamVolume获得最大值，并相应地设置卷，以防使用单个值编辑所有流。因此，如果用户希望将全局卷设置为50%，则获取每个流的最大卷，将其乘以0.5，并将其设置为相应的流。

这会使其变得比必须的更复杂。你可以用它。请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);

可以使用setRingerMode（）方法执行此操作

AudioManager audioManager=(AudioManager)getSystemService(AUDIO_SERVICE);
audioManager.setRingerMode(audioManager.RINGER_MODE_SILENT);

静音和振动振铃器\u模式\u振动标志

取消静音：振铃器\u模式\u正常

提供的答案似乎已被android M（API 23）弃用，因此这是一个替代解决方案

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);
    }
}

希望这能有所帮助……

难道没有更多的流（系统、语音呼叫）吗？我见过那些在真实设备中使用的。此外，没有AudioManager#setStreamVolume（int，int）方法，只有一个方法接受三个参数（一个是要设置的卷）。您可以传递0，但并非所有流都接受。没有类似于此回答中给出的方法。不幸的是，由于API级别为22，已弃用。@Endzeit:请参阅@Lokanath的回答。对于最新的Android，只需将

adjustStreamVolume（）

调用替换为

ADJUST\u MUTE

。完美的解决方案！！如果您保持single method mute/unmute标志参数会更好，但这是可选的：）。

mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_NOTIFICATION, AudioManager.ADJUST_TOGGLE_MUTE, 0);
mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_ALARM, AudioManager.ADJUST_TOGGLE_MUTE, 0);
mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_TOGGLE_MUTE,0);
mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_RING, AudioManager.ADJUST_TOGGLE_MUTE, 0);
mAlramMAnager.adjustStreamVolume(AudioManager.STREAM_SYSTEM, AudioManager.ADJUST_TOGGLE_MUTE, 0);
