Question

大家中午后好！我在expandable listview中面临一个问题＆gt;我没有在expandable listview中得到准确的正确结果。我在每个ListGroupElement中重复使用child。我得到这种格式的结果：

汽车
1. 新
2. 猫
动物
1. 新-----------------重复
2. 猫

这是我的json格式：

  {
    "status": 1,
    "category": [
        {
            "id": 1,
            "category_name_en": "car",

                },
                {

                    "updated_at": "Sep 4 2017 7:15 PM"
                }
            ]
        },
        {

            "sub_category": [
                {
                    "id": 2,
                    "sub_category_name_en": "**Dogs**",
                    "sub_category_name_ar": "Dogs",
                    "sub_description_en": "",
                    "sub_description_ar": "",
                    "status": "A",
                    "created_at": "Sep 4 2017 6:50 PM",
                    "updated_at": "Sep 4 2017 6:50 PM"
                },
                {
                    "id": 3,
                    "sub_category_name_en": "**Cat**",
                    "sub_category_name_ar": "Cat",
                    "sub_description_en": "",

                    "updated_at": "Sep 4 2017 6:51 PM"
                }
            ]
        }
    ]

我想要这种格式的结果

汽车
1. 奥迪
2. 新
动物
1. 猫
2. 狗

这是我的解析

     private ArrayList<ModelGroup> modelgroup = null;
    private ArrayList<ModelChild> modelchild = null;

    private ArrayList<ArrayList<ModelChild>> ListChildXXXXXXXXX= null;
 ModelGroup LT = null;
                    ModelChild CT = null;

                    String response = result.getResult().toString();
                    JSONObject jsonRoot = new JSONObject(response);
                    JSONArray jsonArray = jsonRoot.getJSONArray("category");

                    for (int i = 0; i < jsonArray.length(); i++) {
                        LT= new ModelGroup();

                        JSONObject jsonObject = jsonArray.getJSONObject(i);
                        LT.setCat_name(jsonObject.getString("category_name_en"));
                      //  LT.setCat_id(jsonObject.getString("id"));
                        modelgroup.add(LT);
                        JSONArray jsonArray1 = jsonObject.getJSONArray("sub_category");
                        for (int j = 0; j < jsonArray1.length(); j++) {
                            CT = new ModelChild();

                            JSONObject jsonObject2 = null;

                            jsonObject2 = jsonArray1.getJSONObject(j);

                            CT.setSub_category_name_en(jsonObject2.getString("sub_category_name_en"));

                        }

                     //get(i).get(i).add(CT);

                        modelchild.add(CT);

                            ListChildXXXXXXXXX.add(modelchild);

                    }

请纠正我在哪里做错了，谢谢你的帮助。
