//        int transY = fontMetricesBottom - b.getBounds().bottom;
//        int transY -= paint.getFontMetricsInt().descent;

        // 因為 TextView 加了 lineSpacing 之後會導致這裏的 bottom、top 參數與單行情況不一樣，所以不用 bottom、top，而使用 fontMetrics 的高度來計算
        int fontMetricesTop = y + paint.getFontMetricsInt().top;
        int fontMetricesBottom = fontMetricesTop + (paint.getFontMetricsInt().bottom - paint.getFontMetricsInt().top);
        int transY = fontMetricesTop + ((fontMetricesBottom - fontMetricesTop) / 2) - ((b.getBounds().bottom - b.getBounds().top) / 2) - mTop;

        transY += mTranslateY;
