Calculation:

Write a simple Java program to:

Public class tohex {    public static void main (String[]  args)  {        system.out.println ("16 Binary for Transparency percentage:");         for  (int i = 0; i <= 100;  i++)  {            float temp=255*i *1.0f/100f;            int round =  Math.Round (temp);//Rounding             String  Hexstring = integer.tohexstring (Round);             if  (Hexstring.length () <2)  {                 hexstring+= "0";             } &nBsp;          system.out.println ("     Percentage: "+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.
