计算任意字符串的十六进制颜色代码 [英] Compute hex color code for an arbitrary string

问题描述

是否有将任意字符串映射为HEX COLOR代码的方法。我试图使用字符串hashcode计算字符串的十六进制数。现在我需要将这个十六进制数转换为十六进制数字，在十六进制颜色代码范围。任何建议？

Is there a way to map an arbitrary string to a HEX COLOR code. I tried to compute the HEX number for string using string hashcode. Now I need to convert this hex number to six digits which are in HEX color code range. Any suggestions ?

String [] programs = {"XYZ", "TEST1", "TEST2", "TEST3", "SDFSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS"};

for(int i = 0; i < programs.length; i++) {
  System.out.println( programs[i] + " -- " + Integer.toHexString(programs[i].hashCode()));
}

推荐答案

关心颜色的含义，你可以拆分int的位（删除第一个为RGB而不是ARGB）

If you don't really care about the "meaning" of the color you can just split up the bits of the int (remove the first for just RGB instead of ARGB)

String [] programs = {"XYZ", "TEST1", "TEST2", "TEST3", "SDFSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS"};

for(int i = 0; i < programs.length; i++) {
  System.out.println( programs[i] + " -- " + intToARGB(programs[i].hashCode()));
}
....
public static String intToARGB(int i){
    return Integer.toHexString(((i>>24)&0xFF))+
        Integer.toHexString(((i>>16)&0xFF))+
        Integer.toHexString(((i>>8)&0xFF))+
        Integer.toHexString((i&0xFF));
}
