First learn about touchlisteners and calculate amount of `x` swiped and get it into min-max value and set it to volume — karanatwal.github.io, May 03 '18 at 05:24

I've implemented volume control in one of my online radio stream project like this, and it worked fine for me

        private SeekBar volumeSeekbar;

        volumeSeekbar = (SeekBar) findViewById(R.id.seekBarVolume);
        volumeSeekbar.setThumbOffset(5);
        volumeSeekbar.setMax(audioManager
                .getStreamMaxVolume(AudioManager.STREAM_MUSIC));
        volumeSeekbar.setProgress(audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC));


    volumeSeekbar.setOnSeekBarChangeListener(this);

    private void volume(String volume) {
    if (volume.equals("up")) {
        audioManager.adjustVolume(AudioManager.ADJUST_RAISE,
                AudioManager.FLAG_SHOW_UI);

        volumeSeekbar.setProgress(audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC));

    } else if (volume.equals("down")) {
        audioManager.adjustVolume(AudioManager.ADJUST_LOWER,
                AudioManager.FLAG_SHOW_UI);

        volumeSeekbar.setProgress(audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC));

    } else if (volume.equals("max")) {

        if (isMute)
            unmute();
        audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
                audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),
                0);
        volumeSeekbar.setProgress(audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC));
    }
}

public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)) {
        volume("down");
    }

    if ((keyCode == KeyEvent.KEYCODE_VOLUME_UP)) {
        volume("up");
    }

    if ((keyCode == KeyEvent.KEYCODE_BACK)) {
        moveTaskToBack(true);

    }
    return true;
}

 @Override
public void onProgressChanged(SeekBar seekBar, int progress,
                              boolean fromUser) {
    audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, progress, 0);
    if (AudioManager.STREAM_MUSIC > 0) {
        buttonMinMute.setBackgroundResource(R.drawable.speaker_low_range);
        audioManager.setStreamMute(AudioManager.STREAM_MUSIC, false);
    }

}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {

}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {

}
