Android - 将ARGB颜色转换为HEX

Question

I have an ARGB Color (looks like 255 200 200 000 ). I've tried to convert it into Hex format with this code:

---

    String col = "#" + Integer.toString(Color.alpha(img.getPixel(j, i)), 16) + 
        Integer.toString(Color.red(img.getPixel(j, i)), 16) + 
        Integer.toString(Color.green(img.getPixel(j, i)), 16) + 
        Integer.toString(Color.blue(img.getPixel(j, i)), 16);

---

But I'm gettng this ( #FFC8C8 ) instead of ( #FFC8C800 ). So all numbers below 10 are writing without zeros. How I can fix that code to make it work properly?

PS Excuse for my English

Answer 1

您可以使用

String hexColor = String.format("#%08X", img.getPixel(j, i));
