在AudioManager中使用getRingerMode()方法。

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

switch (am.getRingerMode()) {
    case AudioManager.RINGER_MODE_SILENT:
        Log.i("MyApp","Silent mode");
        break;
    case AudioManager.RINGER_MODE_VIBRATE:
        Log.i("MyApp","Vibrate mode");
        break;
    case AudioManager.RINGER_MODE_NORMAL:
        Log.i("MyApp","Normal mode");
        break;
}

以下代码检查手机是否未处于静音模式，然后播放蜂鸣音，格式为kotlin：

val manager = getSystemService(Context.AUDIO_SERVICE) as AudioManager
    manager.setStreamVolume(AudioManager.STREAM_MUSIC, 10, 0)
    val notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
    val player: MediaPlayer = MediaPlayer.create(applicationContext, notification)
    if(manager.ringerMode != AudioManager.RINGER_MODE_SILENT)
        player.start()

如果您要收听振铃器模式更改，即静音或振动或正常的任何更改，您可以在活动中设置广播接收器，如下所示。

private val volumeKeyReceiver: VolumeKeyReceiver by lazy {
        VolumeKeyReceiver()
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        registerBroadcastListener()
    }

    private fun registerBroadcastListener() {
        val intentFilter = IntentFilter()
        intentFilter.addAction("android.media.RINGER_MODE_CHANGED")
        registerReceiver(volumeKeyReceiver, intentFilter)
    }

并在活动被破坏时取消注册，如下所示。

override fun onDestroy() {
        super.onDestroy()
        unregisterReceiver(volumeKeyReceiver)
    }

并在清单中登记接收者

<receiver android:name=".VolumeKeyReceiver"/>

广播接收器来了

class VolumeKeyReceiver : BroadcastReceiver() {
    override fun onReceive(context: Context?, intent: Intent?) {
        //Implement Logic
        val audioManager =
            context?.getSystemService(Context.AUDIO_SERVICE) as android.media.AudioManager
        when (audioManager.ringerMode) {
            android.media.AudioManager.RINGER_MODE_SILENT -> Log.d(
                "VolumeKeyReceiver",
                "Silent mode"
            )
            android.media.AudioManager.RINGER_MODE_VIBRATE -> Log.d(
                "VolumeKeyReceiver",
                "Vibrate mode"
            )
            android.media.AudioManager.RINGER_MODE_NORMAL -> Log.d(
                "VolumeKeyReceiver",
                "Normal mode"
            )
        }
    }
}
