Как получить массив JSON внутри объекта JSON и выполнить итерацию

/ 10 июля 2020

Я пытаюсь установить связь с API с помощью Retrofit в Android Stud ios, но не знаю, как получить массив JSON в объекте JSON.

JSON: 

{
   "result":{
      "status":{
         "msg":"success",
         "code":200,
         "action":2,
         "execution_time":"0.505"
      },
      "page":"1",
      "page_size":"40",
      "q":"iphone",
      "sort":"default",
      "tmall":false,
      "free_shiping":false,
      "total_results":1924963,
      "ip":"13.228.169.5",
      "item":[
         {
            "num_iid":619354061232,
            "pic":"https://img.alicdn.com/bao/uploaded/i4/2150908574/O1CN01O3Akm82DCwTChbTXg_!!2150908574.jpg",
            "title":"Apple/苹果 iPhone XR iphone xs max手机双卡国行原装4G xr苹果x",
            "price":"6000",
            "promotion_price":"2009",
            "sales":1973,
            "loc":"广东 深圳",
            "seller_id":2150908574,
            "seller_nick":"实惠馆超市",
            "shop_title":"新魔方数码",
            "user_type":0,
            "detail_url":"https://item.taobao.com/item.htm?id=619354061232",
            "delivery_fee":"0.00"
         }
        "item":[...]

Метод: 

    private void taobaoSearch(){
        TaobaoInterface retrofitInterface = RetrofitInstance.getRetrofitInstanceTaobao().create(TaobaoInterface.class);
        Call<TaobaoModel> listCall = retrofitInterface.getTaobao("item_search", "40","default", "iphone","taobao-api.p.rapidapi.com", "//apikey hidden");
        listCall.enqueue(new Callback<TaobaoModel>() {
            @Override
            public void onResponse(Call<TaobaoModel> call, Response<TaobaoModel> response) {
                //not sure what to do here

                }

            @Override
            public void onFailure(Call<TaobaoModel> call, Throwable t) {
                System.out.println("FAILED");
                System.out.println(call);
                t.printStackTrace();
            }
        });

    }

TaobaoModel:

    }

    public void setExecution_time(String execution_time) {
        this.execution_time = execution_time;
    }
}

Я намерен получить JSON массив item и отобразить из него title,price,pic,detail_url. Я узнал, как отображать его по одному, но не смог найти, как выполнить итерацию объекта JSON, чтобы я мог отображать данные в виде списка. Пожалуйста, помогите, я новичок в этом, и я застрял довольно долго. Если вы хотите увидеть мой интерфейс, модифицируйте экземпляр et c, просто дайте мне знать.
