比如hex:b5c4bbb0转出来的byte应该是:75 60 69 80

是不是只能自己编程来实现呀(也许我没有完全理解你的意思,你可以在说明一下吗)

hrhr已经解决问题

int len = data.length();
byte[] ba = new byte[len / 2];
int i = 0, j = 0, c;
while (i < len) { c = Character.digit(data.charAt(i++), 16) << 4;
c = c + Character.digit(data.charAt(i++), 16);
ba[j++] = (byte) c;
}
return ba;
}

length返回的是数组元素个数，但为什么要除二
