java - 如何在 Android 中合并两个 JSON 数组？

Question

我有一个像这样的 JSON 响应:

[{"ProjectID":1,"ProjectName":"Test","UserID":[1,3,5,7],"RSID":[2,4,6,8]}]

但我需要像这样合并它:

[{"ProjectID":1,"ProjectName":"Test","RS":[{"UserID":1,"RSID":2},{"UserID":3,"RSID":4},{"UserID":5,"RSID":6},{"UserID":7,"RSID":8}
]}]

这可以做到吗？

下面的代码是使用 Java 执行相同的任务:

 JSONParser parser = new JSONParser();
    String oldJSON = "[{\"ProjectID\":1,\"ProjectName\":\"Test\",\"UserID\":[1,3,5,7],\"RSID\":[2,4,6,8]}]";

    JSONObject newJSON = new JSONObject();
    Object obj = parser.parse(oldJSON);
    JSONArray mainArray = (JSONArray) obj;
    JSONObject objects = (JSONObject) mainArray.get(0);

    newJSON.put("ProjectID", objects.get("ProjectID"));
    newJSON.put("ProjectName", objects.get("ProjectName"));

    JSONArray userId = (JSONArray) objects.get("UserID");
    JSONArray rsid = (JSONArray) objects.get("RSID");
    JSONArray newArr = new JSONArray();

    for (int i = 0; i < userId.size(); i++) {
        JSONObject combine = new JSONObject();
        System.out.println("inside array" + userId.get(i));
        combine.put("UserID", userId.get(i));
        combine.put("RSID", rsid.get(i));
        newArr.add(combine);
    }
    newJSON.put("RS", newArr);
    System.out.println("json" + newJSON.toJSONString());
