如何在android中以编程方式增加铃声和通知量

Question

我正在尝试启用振铃器正常模式并以编程方式增加音量.

AudioManager mobilemode = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
//   int streamMaxVolume = mobilemode.getStreamMaxVolume(AudioManager.STREAM_RING);
switch (mobilemode.getRingerMode()) {
    case AudioManager.RINGER_MODE_SILENT:
        Log.i("MyApp","Silent mode");

        mobilemode.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
        mobilemode.setStreamVolume (AudioManager.STREAM_MUSIC,mobilemode.getStreamMaxVolume(AudioManager.STREAM_MUSIC),0);
        break;
    case AudioManager.RINGER_MODE_VIBRATE:
        Log.i("MyApp","Vibrate mode");                     
        mobilemode.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
        mobilemode.setStreamVolume (AudioManager.STREAM_MUSIC,mobilemode.getStreamMaxVolume(AudioManager.STREAM_MUSIC),0);
        break;
    case AudioManager.RINGER_MODE_NORMAL:
        Log.i("MyApp","Normal mode");
        break;
}

但它启用正常模式.但我不能增加音量.

请允许我以任何方式以编程方式增加音量..

更换线

mobilemode.setStreamVolume (AudioManager.STREAM_MUSIC,mobilemode.getStreamMaxVolume(AudioManager.STREAM_MUSIC),0);

与下线

mobilemode.setStreamVolume(AudioManager.STREAM_RING,audioManager.getStreamMaxVolume(AudioManager.STREAM_RING),0);
