如何从此JSON获取Name和UserName
String str =＆＃34; {Name = jack，UserName = Jacki}＆＃34;
在java android中

Answer 1

试试这个，代码将使用scanner类及其findInLine（）方法

String str="{Name=jack,UserName=Jacki}";
Scanner sc=new Scanner(str);
sc.findInLine("Name=");

 if(sc.hasNext())
 {
     System.out.println(sc.next()); //This will print Name you can store it in variable as well
  }


sc.findInLine("UserName=");

if(sc.hasNext())
 {
     System.out.println(sc.next()); //This will print UserName you can store it in variable as well
  }

Answer 2

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Sample
{
    public static void main (String[] args) throws java.lang.Exception
    {
        String str="{Name=jack,UserName=Jacki}";
        String[] str1=str.split(",");
        System.out.print(str1[0].substring(1));
        System.out.print(str1[1].substring(0,str1[1].length()-1));
    }
}

所以在这个方法中你基本上把字符串分成“，”。这会给你{Name = jack和UserName = Jacki}。接下来的两个语句只解析这两个新字符串并删除“{”和“}”。
