Calculation:

Write a simple Java program to:

public class ToHex {    public static void main(String[] args) {        System.out.println("透明度百分比对应的十六进制:");        for (int i = 0; i <= 100; i++) {            float temp=255*i*1.0f/100f;            int round = Math.round(temp);//四舍五入            String hexString = Integer.toHexString(round);            if (hexString.length()<2) {                hexString+="0";            }            System.out.println("    百分比:"+i+"%"+"  HEX: "+hexString.toUpperCase());        }    }    }

Other:

Android 的透明度在alpha 为0~1.在xml中用16进制表示.

For example: Full transparency #00000000 , followed by six 0 for Black, and the front 00 for transparency of 0.

You can also use the calculator 255 * 50% and then switch to programmer mode, you can see the corresponding hexadecimal.
