如何在 ArrayList 中存储 Json 数组

Question

我正在从 json 获取数据。在我的 json 中有 2 个数组。

1. 主阵列
2. 在主数组下有几个对象，在那个对象下我得到另一个数组。

问题是，当读取第一个对象时，它会转到 ParseLiveComment（GET CALL 参见下面的代码）并读取所有对象，然后返回所有注释并显示在列表中

但我想，当第一个对象读取时，它会转到 ParseLiveComment（GET CALL 参见下面的代码），然后添加第一个对象注释数据并添加到注释数组列表，依此类推

这是我的 Json

    {
    "status": 1,
    "product": [
        {
            "id": 1,
            "product_name_en": "testProduct",
            "product_name_ar": "testProduct",
            "product_description_en": "This is test product",
            "product_description_ar": "This is test product",
            "link": [
                "http://kartpay.biz/api/v1/file/product/WMZv45E8UCWhIG95ammJSF9GePbz6CjgfskkRPK9.jpg"
            ],

            "user_id": "1",
            "view_count": null,
            "like_count": null,
            "comment_count": 1,
            "comment": [
                {
                    "product_id": "1",
                    "user_id": "1",
                    "comment": "Good and nice product"
                }
            ],
            "first_name_en": null,
            "first_name_ar": null,
            "last_name_en": null,
            "last_name_ar": null,
            "created_at": "Sep 4 2017 8:11 AM",
            "updated_at": "Sep 4 2017 8:11 AM"
        },
        {
            "id": 2,
            "product_name_en": "testProducts",
            "product_name_ar": "testProducts",

                "http://kartpay.biz/api/v1/file/product/LNG9gTlvnHzOpi3Hb5WNoWR8YN1oXuHwOOA6Nbqn.jpg"
            ],
            "starting_price": "1000.000",
            "sub_category_id": "1",
            "status": "A",

            "view_count": null,
            "like_count": null,
            "comment_count": 0,
            "comment": [],
            "first_name_en": null,
            "first_name_ar": null,
            "last_name_en": null,
            "last_name_ar": null,
            "created_at": "Sep 4 2017 8:19 AM",
            "updated_at": "Sep 4 2017 8:19 AM"
        }
]
}

我已成功获取数组列表中的主数组，但我想将该评论数组存储在另一个数组列表中

这是我的两个数组列表的 Pojo 类

 public class CardData implements ECCardData<Comment> {

   private List<Comment> listItems;
 @Override
    public List<Comment> getListItems() {
        return listItems;
    }

    public void setListItems(List<Comment> listItems) {
        this.listItems = listItems;
    }
}

评论 POJO

 public class Comment {

    private String commentText;
    public String getCommentText() {
        return commentText;
    }

    public void setCommentText(String commentText) {
        this.commentText = commentText;
    }
}

这是我的解析

 public static ArrayList<CardData> PaeseLiveProducts(String response) throws JSONException {
ArrayList<CardData> alUser = new ArrayList<>();

  JSONObject jsonRoot = new JSONObject(response);

    JSONArray parentArray = jsonRoot.getJSONArray("product");
    for (int j = 0; j < parentArray.length(); j++) {
        JSONObject finalObject = parentArray.getJSONObject(j);
        CardData user = new CardData();

     int  is=   user.setId(finalObject.getInt("id"));

        Comment comment = new Comment();

        JSONArray jsonArray=finalObject.getJSONArray("link");
        for (int i = 0; i < jsonArray.length(); i++) {
            // Log.d("text", textArray.getString(i) );
            user.setHeadBackgroundResource(jsonArray.getString(i));
        }

        JSONArray jsonArray1 = finalObject.getJSONArray("comment");
        for (int k = 0; k < jsonArray1.length(); k++) {
            // Log.d("text", textArray.getString(i) );
            JSONObject jsonObject2 = jsonArray1.getJSONObject(k);
            comment.setCommentText(jsonObject2.getString("comment"));
        }

        user.setListItems(PaeseLive(response));


        alUser.add(user);


    }
    return alUser;
}

public static ArrayList<Comment> PaeseLiveComment(String response) throws JSONException {

    ArrayList<Comment> alUser = new ArrayList<>();
    JSONObject jsonRoot = new JSONObject(response);
    JSONArray parentArray = jsonRoot.getJSONArray("product");

    for (int j = 0; j < parentArray.length(); j++) {
        JSONObject finalObject = parentArray.getJSONObject(j);
        Comment comment = new Comment();

        JSONArray jsonArray1 = finalObject.getJSONArray("comment");
        for (int k = 0; k < jsonArray1.length(); k++) {
            // Log.d("text", textArray.getString(i) );
            JSONObject jsonObject2 = jsonArray1.getJSONObject(k);
            comment.setCommentText(jsonObject2.getString("comment"));
        }
         alUser.add(comment);

    }
    return alUser;
    // return alUser;
}

你能试试下面的代码吗？ ：

public static ArrayList<Comment> PaeseLiveComment(String response) throws JSONException {

    ArrayList<Comment> alUser = new ArrayList<>();
    JSONObject jsonRoot = new JSONObject(response);
    JSONArray parentArray = jsonRoot.getJSONArray("product");

    for (int j = 0; j < parentArray.length(); j++) {
        JSONObject finalObject = parentArray.getJSONObject(j);

        JSONArray jsonArray1 = finalObject.getJSONArray("comment");
        for (int k = 0; k < jsonArray1.length(); k++) {
            // Log.d("text", textArray.getString(i) );
            Comment comment = new Comment();
            JSONObject jsonObject2 = jsonArray1.getJSONObject(k);
            comment.setCommentText(jsonObject2.getString("comment"));
            alUser.add(comment);
        }

    }
    return alUser;
    // return alUser;
}
