please check this code......

    SeekBar ring = null;
AudioManager mgr = null;
    mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
     ring = (SeekBar) findViewById(R.id.seekBar1);
    initBar(ring, AudioManager.STREAM_RING);

please call the function initbar using your seekbar view instance and stream it will set the music volume as you increase or decrease the seekbar...

private void initBar(SeekBar bar, final int stream) {
    bar.setMax(mgr.getStreamMaxVolume(stream));
    bar.setProgress(mgr.getStreamVolume(stream));

    bar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        public void onProgressChanged(SeekBar bar, int progress,
                boolean fromUser) {
            mgr.setStreamVolume(stream, progress,
                    AudioManager.FLAG_PLAY_SOUND);
        }

        public void onStartTrackingTouch(SeekBar bar) {
            // no-op
        }

        public void onStopTrackingTouch(SeekBar bar) {
            // no-op
        }
    });
}
