RETROFIT 2.0 unbale to acess данные ответа api содержат любой список

Question

Привет, ребята, я ударил одной проблемой, пока я пытаюсь получить доступ к одним из услуг api, все работает нормально. Но моя проблема в обработке ответа.

Я использую переоснащение 2.0

Ниже мой JSON ответ на мой апи

{ 
    "status": 200, 
    "success": "true", 
    "data": [ 
    { 
     "works_node": [ 
     { 
      "works_items": [ 
      { 
       "work_id": "number", 

       "preference": "number", 
       "Task_created_time": "datetime yyyy-mm-dd h:m:s" 
      } 
      ]

Решение

1. Редактировать Json structure
2. Редактировать POJO класс (Datum)

Редактировать Json Структура

data - объект, а не массив.

{ 
    "status": 200, 
    "success": "true", 
    "data": { 
     "works_node": [{ 
      "works_items": [{ 
       "work_id": "number", 
       "preference": "number", 
       "Task_created_time": "datetime yyyy-mm-dd h:m:s" 
      }] 
     }], 
     "questions_node": [{ 
      "questions_items": [{ 
       "q_id": "number", 
       "work_id": "number", 
       "question_text": "string", 
       "preference": "number" 
      }] 
     }], 
     "answers_node": [{ 
      "answers_items": [{ 
       "a_id": "number", 
       "q_id": "number", 
       "answer_text": "string", 
       "prefernce": "number", 
       "point": "number", 
       "is_suggest": "number", 
       "work_id": "number" 
      }] 
     }], 
     "answer_suggestions_node": [{ 
      "answer_suggestions_items": [{ 
       "a_id": "number", 
       "q_id": "number", 
       "answer_suggestion_text": "string", 
       "point": "number", 
       "work_id": "number" 
      }] 
     }] 
    } 
} 

Редактировать POJO класс

перейдите по ссылке ниже и генерировать pojo class снова.

http://www.jsonschema2pojo.org/

И Попробуйте это.

WorkTaskConfig taskConfig = reponse.body(); 

List<WorksNode> worksNode = taskConfig.getData().getWorksNode(); 
List<QuestionsNode> questionsNode = taskConfig.getData().getQuestionsNode(); 
List<AnswersNode> answersNode = taskConfig.getData().getAnswersNode(); 
List<AnswerSuggestionsNode> answerSuggestionsNode = taskConfig.getData().getAnswerSuggestionsNode(); 

Answer 2

Заменить все WorkTaskConfig к JsonElement, если вы столкнулись с какой-то проблемой. и Разобрать вручную с Gson как ..

String apiAllWorkTaskConfigData = response.body().getData(); WorkTaskConfig mWorkTaskConfig = new Gson.fromJson(apiAllworkTaskConfigData,WorkTaskConfig.class);
