Question

我已经从json

下面创建了一个类别的模型类

    "is_active": 1,

}]}

这是我从json

获取类别的模型类

public class ModelCategories {

public static ArrayList<String> id = new ArrayList<String>();
public static ArrayList<String> name = new ArrayList<String>();
}

我知道如何解析json，但我的问题是如何在模型类中存储子类别我是这类场景的新手。

所以请帮助我......

我不知道你为什么要创建像这个ModelCategories这样的模型。如果我必须解决这个问题，我将创建一个名为Category的模型：

  public class Category {
       String id;
       String name;
       int position;
       List<Category> subCategories;
  }

如何从json获取带有模型类的类别和子类别
