Answer 1

因为这是一个没有名字的jsonArray，

请尝试以下操作：

首先从结果中获取JsonArray。

JSONArray json = new JSONArray(your_json_string);

然后从jsonobject获取单个jsonarray，如下所示：

int arrayLength = json.length();

for(int i=0;i<arrayLength;i++){   

 // Get the single object in the array
 JSONObject singleObject = json.getJSONObject(i);

 if (singleObject.has("user")) {

    JSONObject userObject = singleObject.getJSONObject("user");
        // TODO: retrieve user jsonobjects data
 }           
}

Answer 2

尝试以下

String user;
JSONArray data = json.getJSONArray(YOUR_ARRAY); //json is JSONObject
JSONObject object = data.getJSONObject(0);
user = object.getString("user");

Answer 3

试试这个..

JSONArray jsonarray = new JSONArray(response);

for (int i=0; i < jsonarray.length(); i++){
    JSONObject jsob = jsonarray.getJSONObject(i);
    String url = jsob.getString("url");
    //same for remaining like url,forks_url etc.,
    JSONObject files_obj = jsob.getJSONObject("files").getJSONObject("gulpfile-viget-pattern.js");
    String type = files_obj.getString("type");
    //same for remaining like type,language etc.,
    JSONObject user_obj = jsob.getJSONObject("user");
    String login = user_obj.getString("login");     
    //same for remaining like login,url etc.,   
}

Answer 4

在您的Json响应中，您的第一个标记为JSONArray。所以你需要解析像

这样的数据

 JSONArray jarray = new JSONArray(Your_Response);

 for (int i=0; i < jarray.length(); i++){
   JSONObject jb= jarray.getJSONObject(i);
   String url = jb.optString("url");

   JSONObject other_jb= jb.getJSONObject("files").getJSONObject("gulpfile-viget-pattern.js");
   String type = other_jb.optString("type");

   JSONObject jsonObject_of_user = jb.getJSONObject("user");
   String user_login = jsonObject_of_user.optString("login");     

 }

在android中解析json，只对一种对象感兴趣的无名数组
