Android 如何为这种类型的json数据创建pojo类，因为在这种类别和子类别中，只有通过id才能组合关系

在这个json中，我的类别和子类别是组合的，如何在pojo类中设置，如何在可扩展列表视图中设置，请帮助

您必须解析json响应并将不同的类别存储在不同的arraylist中，根据用户对渲染位置的选择，您可以使用所选的arraylist

您可以通过像这样解析json响应来实现这一点

JSONObject jsonObject = new JSONObject(response); // response is the json string that you are gettting from server

    JSONArray jsonArray = jsonObject.getJSONObject("product_categories");

    ArrayList<Categorydisplay> catDisList = new ArrayList<>();
    ArrayList<Defaultdisplay> defaultDisList = new ArrayList<>();

    for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject jsonObject = jsonArray.getJSONObject(i);
        SomeModel someModel = new SomeModel();
        if (jsonObject.has("id")) {
            someModel.setId(jsonObject.getString("id"));
        }
        if (jsonObject.has("name")) {
            someModel.setName(jsonObject.getString("name"));
        }

        so on.....

        if(someModel.getDisplay().equals("default")){
            defaultDisList.add(someModel);
        }else{
            catDisList.add(someModel);
        }

    }

JSONObject JSONObject=新的JSONObject（响应）；//response是从服务器获取的json字符串
JSONArray JSONArray=jsonObject.getJSONObject（“产品类别”）；
ArrayList catDisList=新的ArrayList（）；
ArrayList defaultDisList=新建ArrayList（）；
for（int i=0；i
