解析JSON阵列子对象

我想这个贾森解析成Java代码的Android应用：解析JSON阵列子对象

{ 
"name":"London", 
"coord":{"lon":-0.12574,"lat":51.50853}, 
"country":"GB", 
"cnt":6, 
"list":[{ 
     "dt":1377345600, 
     "temp":{     
        "min":290.42, 
        "max":294.3, 
        "weather":[{ 
           "id":501, 
           "main":"Rain", 
           "icon":"10d"}], 
     { 
     "dt":1377432000, 
     "temp":{ 
        "min":289.81, 
        "max":296.92, 
        "weather":[{ 
           "id":800, 
           "main":"Clear", 
           "icon":"01d"}],}

我怎样才能做到这一点？我知道如何解析单个对象数组，但子对象如何工作？

这是完整的json文件。在jsonlint.com

您的json无效JSON。使用http://jsonlint.com/ –

“解析Java代码”是什么意思？ – Henry

发布了完整的json。 –

用户这种方法来遍历JSON动态

private void parseJson(JSONObject data) { 

     if (data != null) { 
      Iterator<String> it = data.keys(); 
      while (it.hasNext()) { 
       String key = it.next(); 

       try { 
        if (data.get(key) instanceof JSONArray) { 
         JSONArray arry = data.getJSONArray(key); 
         int size = arry.length(); 
         for (int i = 0; i < size; i++) { 
          parseJson(arry.getJSONObject(i)); 
         } 
        } else if (data.get(key) instanceof JSONObject) { 
         parseJson(data.getJSONObject(key)); 
        } else { 
         System.out.println("" + key + " : " + data.optString(key)); 
        } 
       } catch (Throwable e) { 
        System.out.println("" + key + " : " + data.optString(key)); 
        e.printStackTrace(); 

       } 
      } 
     } 
    }

这工作，谢谢！ –

它应该是这样的

{ 
    "name":"London", 
    "coord":{"lon":-0.12574,"lat":51.50853}, 
    "country":"GB", 
    "cnt":6, 
    "list":[{ 
    "dt":1377345600, 
    "temp":{     
       "min":290.42, 
       "max":294.3, 
       "weather":[{ 
          "id":501, 
          "main":"Rain", 
          "icon":"10d"}] 
      } 
    }, 
    { 
    "dt":1377432000, 
    "temp":{ 
       "min":289.81, 
       "max":296.92, 
       "weather":[{ 
          "id":800, 
          "main":"Clear", 
          "icon":"01d"}] 
    } 
}] 
}

你忘了加上括号和逗号。你可以参考这个 http://json.parser.online.fr/

您可以使用JSON-简单。请参阅http://code.google.com/p/json-simple/
