是否可以在 Android 中以编程方式关闭静默模式？

解决方案为您 .

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

//For Normal mode
am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);

//For Silent mode
am.setRingerMode(AudioManager.RINGER_MODE_SILENT);

//For Vibrate mode
am.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);

//SilentToNomal and NormalToSilent device Programatically
 final AudioManager mode = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
//Silent Mode Programatically
mode.setRingerMode(AudioManager.RINGER_MODE_SILENT);

//Normal Mode Programatically
  mode.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
