通过多个JSON对象中的Android

循环

我试图解析JSON对象，部分看起来是这样的：通过多个JSON对象中的Android

{ 
    "status":{ 
    "rcode":200, 
    "message":"OK" 
}, 
"data":{ 
    "0":{ 
    "SubFranchiseID":"0", 
    "OutletID":"607", 
    "OutletName":"Spill ", 
    "BrandID":"403", 
    "Address":"J-349, JP Road, Opp. Apna Bazar, JP Rd, D.N.Nagar, Andheri West, Mumbai, Maharashtra, India", 
    "NeighbourhoodID":"1", 
    "CityID":"1", 
    "Email":null, 
    "Timings":"Everyday: 6 pm to 1:30 am.", 
    "CityRank":null, 
    "Latitude":"19.127473", 
    "Longitude":"72.832545", 
    "Pincode":null, 
    "Landmark":null, 
    "Streetname":null, 
    "BrandName":"Spill ", 
    "OutletURL":"https:\/\/plus.google.com\/111539701326240643109\/about?hl=en-US", 
    "NumCoupons":1, 
    "NeighbourhoodName":"Andheri West", 
    "PhoneNumber":"+91 22 2642 5895", 
    "CityName":"Mumbai", 
    "Distance":8205.2235, 
    "Categories":[ 
     { 
      "OfflineCategoryID":"32", 
      "Name":"Continental", 
      "ParentCategoryID":"1", 
      "CategoryType":"Cuisine" 
     }, 
     { 
      "OfflineCategoryID":"13", 
      "Name":"Bar and Restaurant", 
      "ParentCategoryID":"1", 
      "CategoryType":"TypeOfRestaurant" 
     }, 
     { 
      "OfflineCategoryID":"17", 
      "Name":"Italian", 
      "ParentCategoryID":"1", 
      "CategoryType":"Cuisine" 
     }, 
     { 
      "OfflineCategoryID":"1", 
      "Name":"Restaurant", 
      "ParentCategoryID":null, 
      "CategoryType":"" 
     }, 
     { 
      "OfflineCategoryID":"21", 
      "Name":"North Indian", 
      "ParentCategoryID":"1", 
      "CategoryType":"Cuisine" 
     } 
    ], 
    "LogoURL":"http:\/\/www.google.in\/sitespecific\/media\/generated\/offlineimages\/logo_403.jpg", 
    "CoverURL":"http:\/\/www.google.in\/sitespecific\/media\/generated\/offlineimages\/cover_607.jpg" 
    }, 
"1 "{ 
     "SubFranchiseID":"1", 
    "OutletID":"60", 
    "OutletName":"Bill ", 
     . 
     . 
     . 
     } 
}

个分别有这些objects.I的近35 JSON对象和嵌套JsonArrays “M试图得到这样的数据：

url = new URL(uri); 
     URLConnection connection = url.openConnection(); 
     BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream())); 
     StringBuilder sb = new StringBuilder(); 
     String line = null; 
     while ((line = reader.readLine()) != null) { 
      sb.append(line + "\n"); 
     } 

     reader.close(); 
     json =sb.toString(); 
     JSONObject sjson=json.getJSONObject("data"); 
     Log.d("sjson values-->",sjson+"--"); 
     **JSONObject ssjson=sjson.getJSONObject("0");**

，现在我使每个值是这样的：

String outletName = ssjson.getString("OutletName");

我的问题是有没有更好的方法（循环）通过所有对象（0,1，... 35）并分别获取每个单独的对象的数据。

您应该使用GSON，编写所有的锅炉板JSON解析自己。话虽如此，请至少提供您期望在响应中的准确json，这是有效的，因为这似乎是无效的json结构。 – cafebabe1991

我编辑了json数据，并且尝试使用** Iterator keys = resobj.keys（）; ** ande通过while循环迭代键。由于json数据的名称为“0”，Android Studio无法将json转换为Java Object类。您可以给出有关如何使用Gson解析的深入见解 – Evani

例JSON

{ 
    "status": { 
     "rcode": "200", 
     "message": "Good, you got me!!!" 
    }, 
    "data": [ 
     { 
      "SubFranchiseID": "0", 
      "OutletID": "607", 
      "OutletName": "Spill", 

     }, 
     { 
      "SubFranchiseID": "0", 
      "OutletID": "607", 
      "OutletName": "Spill" 
     } 
    ] 
}

代表在普通的Java类与吸气剂的术语和制定者
的JSON

首先创建一个根类（根对象）

public class Root { 
    //For the status object 
    private Status status; 
    //For the array of data objects 
    private List<Data> data; 

    //create setters and getters for the two properties. 
} 

public class Status { 

    private String rcode; 
    //this maps to the rcode in the status object in json 
    private String message; 
    //create setters and getters for the two 
} 

public class Data { 
    private String SubFranchiseID; 
    private String OutletID; 
    private String OutletName; 

//create setters and getters for these properties. 
}

现在，让我们做GSON魔（了JSON到现成的类的序列化）

reader.close(); 
json =sb.toString(); 

Root root = new Gson().fromJson(response, Root.class); 
//get the rcode 
if(root.getStatus().getrCode().equalsIgnoreCase("200")) 
{ 
    //print the data. 
    for(Data d : root.getData()) { 
     System.out.println(d.getSubFranchiseID()+"-"+d.getOutletID()+"-"+d.getOutletName()); 

    } 
}

使用GSON一张小纸条。

1.) The property names inside the classes should match the property in the json or else use a `@SerializeName("propertyname")`. 

2.) An array of objects would map to List<YourObject> , for eg : the data property in the json. 

3.) You can have default value for your properties without creating getters and setters for them like 

private boolean isJson = true;

感谢您的帮助。在Json Array（“Categories”）之前，我有很多像“Outletname”，“OutletID”等“data” - >“0”中的json对象。我为我的数据创建了一个模型类。现在我想使用Gson来读取json对象的数据。 – Evani

这很简单..你看到我写的for循环，这是迭代数据的方式。 – cafebabe1991
