How do you get/set media volume (not ringtone volume) in Android?
Is there a way to get/set media volume? I have tried the following:
AudioManager audio = (AudioManager) get开发者_开发知识库SystemService(Context.AUDIO_SERVICE);
int currentVolume = audio.getStreamVolume(AudioManager.STREAM_RING);
but it returns the ringtone volume.
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;
}
}
Instead of AudioManager.STREAM_RING
you shoul use AudioManager.STREAM_MUSIC
This question has already discussed here.
AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
int currentVolume = audio.getStreamVolume(AudioManager.STREAM_MUSIC);
int maxVolume = audio.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
float percent = 0.7f;
int seventyVolume = (int) (maxVolume*percent);
audio.setStreamVolume(AudioManager.STREAM_MUSIC, seventyVolume, 0);
Have a try with this:
setVolumeControlStream(AudioManager.STREAM_MUSIC);
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);
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;
}
The following code will set the media stream volume to max:
AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),
AudioManager.FLAG_SHOW_UI);
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
