    } else {
        int left = seekBar.getLeft() + seekBar.getPaddingLeft();
        int right = seekBar.getRight() - seekBar.getPaddingRight();
        float width = (float) (seekBar.getProgress() * (right - left)) / seekBar.getMax();
        posX = Math.round(width) + seekBar.getThumbOffset();
    }
    return posX;
}
