But have a seekbar and want

Answer 1

You can use the following code to handle Volume using a SeekBar:

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

SeekBar sbVolumeBooster = (SeekBar) findViewById(R.id.sbVolumeBooster);
sbVolumeBooster.setMax(audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC)); 
sbVolumeBooster.setProgress(audioManager.getStreamVolume(AudioManager.STREAM_MUSIC));  

sbVolumeBooster.setOnSeekBarChangeListener(new OnSeekBarChangeListener() 
{
    @Override
    public void onStopTrackingTouch(SeekBar arg0) 
    {
    }

    @Override
    public void onStartTrackingTouch(SeekBar arg0) 
    {
    }

    @Override
    public void onProgressChanged(SeekBar arg0, int progress, boolean arg2) 
    {
        audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
                progress, 0);  // 0 can also be changed to AudioManager.FLAG_PLAY_SOUND
    }
});
