【问题描述】：

这是我的 JSON 数据：

{  
   "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",
                  "location":"xzxzx",
                  "time":"2016-06-21 12:59:49"
               },
               {  
                  "id":"4",
                  "name":"ZA",
                  "location":"BU",
                  "time":"2016-06-23 13:04:25"
               },
               {  
                  "id":"5",
                  "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"
         }
      }
   ]
}

我想将这些数据放入 Android 中的数组列表中。

【问题讨论】：

JSON 格式不正确，请更新。
首先尝试你自己，做一些谷歌搜索。提前致谢
此 JSON 响应未格式化。您可以使用任何在线 JSON 格式化程序对其进行检查。

【解决方案1】：

您的 JSON 数据无效，我根据需要对有效 JSON 数据进行了更正。 检查有效的 JSON 数据如下：

{
    "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",
                "location": "xzxzx",
                "time": "2016-06-21 12:59:49"
            }, {
                "id": "4",
                "name": "ZA",
                "location": "BU",
                "time": "2016-06-23 13:04:25"
            }, {
                "id": "5",
                "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"
        }
    }]
}

【解决方案2】：

亲爱的，现在你JSON 响应格式不正确，因此无法解析。但是一旦你更正它，你就可以使用谷歌GSON库来解析数组。在您的项目中包含 Google GSON 库，使用：compile 'com.google.code.gson:gson:2.3'

您可以将 JSON 响应解析为。

JSONObject objdataList = jsonObj.getJSONObject("data");
JSONArray jsonDataList = objDataList.getJSONArray("alldata");
ArrayList<AllData> records = new Gson().fromJson(jsonDataList.toString(), new TypeToken<List<AllData>>(){}.getType());

快乐编码:)

【解决方案3】：

首先，你给的json有错误。从json中，我们可以使用gson来解析json，看起来像这样

    Gson gson = new Gson();
    Person person = gson.fromJson(responseString.toString(),Person.class);
    List<Person.AlldataBean> list = new ArrayList<Person.AlldataBean>();
    list.addAll(person.getAlldata());

这样做之后，你可以得到列表对象，然后你可以从列表对象。
