java - 如何在Json中定义一个数据结构，结构的顶部是对象的名称？

Question

我正在处理 json，我真的需要得到这个结构:

{

"Identidade":

       [ 

           {  "numero": 1704,  "numeroFinal": 1804,  "id": 28 }, 
           {  "numero": 1806,  "numeroFinal": 1905,  "id": 28 }, 
           {  "numero": 1705,  "numeroFinal": 1706,  "id": 29 }, 
           {  "numero": 1707,  "numeroFinal": 1807,  "id": 30 }

       ]

}

但是到现在我只能弄到这一个，还得能在最上面写上**Identidade**

   [ 

       {  "numero": 1704,  "numeroFinal": 1804,  "id": 28 }, 
       {  "numero": 1806,  "numeroFinal": 1905,  "id": 28 }, 
       {  "numero": 1705,  "numeroFinal": 1706,  "id": 29 }, 
       {  "numero": 1707,  "numeroFinal": 1807,  "id": 30 }

   ]

下面的代码是我当前的实现。

public void writeJsonStream(String file, List<Identidade> iden) throws IOException {

    JsonWriter writer = new JsonWriter(new OutputStreamWriter(m_Context.openFileOutput(file, Context.MODE_PRIVATE)));
    writer.setIndent(" ");
    writeArray(writer, util);
    writer.close();
}


public void writeArray(JsonWriter writer, List<Identidade> iden) throws IOException {
    writer.beginArray();
    for (Identidade i : iden) {
        writeIdentidade(writer, i);
    }
    writer.endArray();
}

public void writeIdentidade(JsonWriter writer, Identidade iden) throws IOException 

    writer.beginObject();
    writer.name("numero").value(iden.getM_numero());
    writer.name("numeroFinal").value(iden.numeroFinal());
    writer.name("id").value(iden.getID());
    writer.endObject();
}

有人可以提示我如何添加 ** Identidade** 吗？

Answer 1

 {
  "status": "100",
  "cart_qty": 0,
  "user": [
    {
      "pro_id": "63",
      "pro_title": "Nikon S9400 Advanced Point & Shoot Camera  (Red)",
      "pro_price": "16000.00",
      "pro_disprice": "12000.00",
      "pro_discount_percentage": 25,
      "pro_Img": [
        "http://backslashinfotech.in/laravel_Ecommerce/assets/product/nikon-coolpix-s9400-advance-point-and-shoot-original-imadgx8twu6buaag.jpeg",
        "http://backslashinfotech.in/laravel_Ecommerce/assets/product/nikon-coolpix-s9400-advance-point-and-shoot-original-imadgx8ty6rvx2dn.jpeg"
      ],
      "created_date": "07/13/2017",
      "pro_image_count": "1",
      "pro_qty": "23",
      "hit_count": "0",
      "sold_status": "1",
      "whishlist": 0
    },
  ]
}

这是json，下面是android端的逻辑

try {
            JSONObject jsonObject= new JSONObject("respones");
            String status=jsonObject.getString("status");
            String scart_qty=jsonObject.getString("cart_qty");

            JSONArray user= jsonObject.getJSONArray("user");
            for (int i=0;i<user.length();i++){
                JSONObject json_data = user.getJSONObject(i);
                Log.e("pro_title",json_data.getString("pro_title"));
                Log.e("pro_price",json_data.getString("pro_price"));
                Log.e("pro_disprice",json_data.getString("pro_disprice"));
                Log.e("pro_discount_percentage",json_data.getString("pro_discount_percentage"));


                JSONArray itemArray=json_data.getJSONArray("pro_Img");
                for (int j = 0; j < itemArray.length(); j++) {
                    String value=itemArray.getString(j);
                    Log.e("PHOTOS_URL", j+"="+value);
                }
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
