String to Byte Value

 功能：把一段逗号分割字符串转换为byte数组

例子：String "4,2,1,13,14,4,7,22,13,12,23,6,23,28,8,3,12,3,22,10,3,12,24,13,16,17,4,22,13,26,23"

转换完毕后成为byte {4,2,1,13,14,4,7,22,13,12,23,6,23,28,8,3,12,3,22,10,3,12,24,13,16,17,4,22,13,26,23};

 

int validLength = 0;
  for(int i = value.length; --i >= 0;) {
   if(value[i] == ',') {
    validLength++;
    continue;
   }
  }
 // System.out.println("validLength::" + validLength);
  info = new byte[++validLength];
  
  String script = new String(getText());
  String sep = ",";
  int begin = 0, end, index = 0;
  
  while(true) {
   end = script.indexOf(sep, begin);
   if(end < 0) {
    info[index++] = Byte.parseByte(script.substring(begin));
    break;
   }
   info[index++] = Byte.parseByte(script.substring(begin, end));
   begin = end + 1;
  }
