Question

如何以编程方式在来电时静音Android手机铃声？（就像在来电时按电源按钮这样做？）

我知道setStreamMute和adjustStreamVolume，但我认为还有更好的方法。

在构建版本23（棉花糖）及更高版本中不推荐使用

setStreamMute()。您可以将adjustStreamVolume()用于棉花糖及以上。

public void adjustAudio(boolean setMute) {
    AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        int adJustMute;
        if (setMute) {
            adJustMute = AudioManager.ADJUST_MUTE;
        } else {
            adJustMute = AudioManager.ADJUST_UNMUTE;
        }
        audioManager.adjustStreamVolume(AudioManager.STREAM_NOTIFICATION, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_ALARM, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_RING, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_SYSTEM, adJustMute, 0);
    } else {
        audioManager.setStreamMute(AudioManager.STREAM_NOTIFICATION, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_ALARM, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_MUSIC, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_RING, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_SYSTEM, setMute);
    }
}

您可以像这样调用此方法

adjustAudio(true) // To mute all the system, ringer, alarm, music, notification sounds on any event like button click.

adjustAudio(false) // To unmute all the system, ringer, alarm, music, notification sounds on any event like button click.
