Good Day

Use this
public override bool OnKeyUp(Keycode keyCode, KeyEvent e)
{
    if (keyCode == Keycode.VolumeDown)
    {
        return true;
    }

    if (keyCode == Keycode.VolumeUp)
    {
        return true;
    }
    return base.OnKeyUp(keyCode, e);
}

public override bool OnKeyDown(Keycode keyCode, KeyEvent e)
{
    if (keyCode == Keycode.VolumeDown)
    {
        return true;
    }

    if (keyCode == Keycode.VolumeUp)
    {
        return true;
    }
    return base.OnKeyDown(keyCode, e);
}
Thank you :)
