How do you get/set media volume (not ringtone volume) in Android?

Question

Is there a way to get/set media volume? I have tried the following:

AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
int currentV         


        

Answer 1

private AudioManager audio;

Inside onCreate:

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

Override onKeyDown:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    switch (keyCode) {
    case KeyEvent.KEYCODE_VOLUME_UP:
        audio.adjustStreamVolume(AudioManager.STREAM_MUSIC,
                AudioManager.ADJUST_RAISE, AudioManager.FLAG_SHOW_UI);
        return true;
    case KeyEvent.KEYCODE_VOLUME_DOWN:
        audio.adjustStreamVolume(AudioManager.STREAM_MUSIC,
                AudioManager.ADJUST_LOWER, AudioManager.FLAG_SHOW_UI);
        return true;
    default:
        return false;
    }
}

If you happen to have a volume bar that you want to adjust –similar to what you see on iPhone's iPod app– here's how.

    @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

    switch (keyCode) {
    case KeyEvent.KEYCODE_VOLUME_UP:
        audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_RAISE, AudioManager.FLAG_SHOW_UI);
        //Raise the Volume Bar on the Screen
        volumeControl.setProgress( audioManager.getStreamVolume(AudioManager.STREAM_MUSIC)
                + AudioManager.ADJUST_RAISE);
        return true;
    case KeyEvent.KEYCODE_VOLUME_DOWN:
        //Adjust the Volume
        audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_LOWER, AudioManager.FLAG_SHOW_UI);
        //Lower the VOlume Bar on the Screen
        volumeControl.setProgress(audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC)
                + AudioManager.ADJUST_LOWER);
        return true;
    default:
        return false;
    }

Answer 3

To set volume to 0

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);

To set volume to full

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

the volume can be adjusted by changing the index value between 0 and 20

Answer 4

You can set your activity to use a specific volume. In your activity, use one of the following:

this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
this.setVolumeControlStream(AudioManager.STREAM_RING);  
this.setVolumeControlStream(AudioManager.STREAM_ALARM);  
this.setVolumeControlStream(AudioManager.STREAM_NOTIFICATION);  
this.setVolumeControlStream(AudioManager.STREAM_SYSTEM);  
this.setVolumeControlStream(AudioManager.STREAM_VOICECALL); 

Answer 5

Instead of AudioManager.STREAM_RING you shoul use AudioManager.STREAM_MUSIC This question has already discussed here.

Answer 6

Have a try with this:

setVolumeControlStream(AudioManager.STREAM_MUSIC);
