如何将具有多个键值的JSON字符串转换为Android中的JSON对象

Question

This is my JSON data:

{  
   "alldata":[  
      {  
         "college1":{  
            "data":[  
               {

                  "time":"2016-06-21 12:49:38"
               },
               {  
                  "id":"3",
                  "name":"xcxc",

                  "time":"2016-06-21 12:59:49"
               },
               {  
                  "id":"4",
                  "name":"ZA",

                  "name":"df",
                  "location":"ok",
                  "time":"2016-06-20{"                  id":"12",
                  "name":"vbnb",
                  "location":"sf",
                  "time":"2016-06-23 11:08:47"
               },
               {  
                  "id":"13",
                  "name":"az",
                  "location":"vgfjghgbhjj",
                  "time":"2016-06-24 12:13:44"
               }
            ],
            "last_date":"2016-06-24 12:13:44"
         }
      },
      {  
         "product1":{  
            "data":[  
               {  
                  "id":"1",
                  "productname":"soapq",
                  "quantity":"2",
                  "time":"2016-06-23 13:12:27"
               },
               {  
                  "id":"2",
                  "productname":"VCVC",
                  "quantity":"3",
                  "time":"2016-06-23 13:12:13"
               },
               {  
                  "id":"3",
                  "productname":"fym",
                  "quantity":"3",
                  "time":"2016-06-23 13:12:53"
               }
            ],
            "last_date":"2016-06-23 13:12:53"
         }
      }
   ]
}

I want to get these data in to arraylist in Android.

Your JSON data is not valid, i done with corrections as needed for valid JSON data. Check Valid JSON data as follows :

{
    "alldata": [{
        "college1": {
            "data": [{
                "id": "1",
                "name": "nithin",
                "location": "alkd",
                "time": "2016-06-24 12:02:28"
            }, {
                "id": "2",
                "name": "xxx",
                "location": "sdsdvxc",
                "time": "2016-06-21 12:49:38"
            }, {
                "id": "3",
                "name": "xcxc",
