android - 如何在来电时静音电话铃声

Question

如何以编程方式使 Android 手机在来电时静音？（比如在来电时按电源按钮）？

我知道setStreamMuteand adjustStreamVolume，但我认为有更好的方法。

setStreamMute()在 Build 版本 23 (marshmallow) 及以上版本中已弃用。您可以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);
    }
}

你可以像这样调用这个方法，

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.
