我在android中映射 gson 响应，在gson中从服务器获取响应，我找到了一个名为＆＃34; 0＆＃34;的数组，如何将其映射为是整数类型所以我在这里做错了什么。请看这里。

        "sub_departments_count": 1
      }
    ]
  },
  "errors": false
}

这是我的映射类。

public class DepartmentsData {
public String result;
public String message;
public DepatmentData data;
public boolean errors ;}

第二课

public class DepatmentData {
public List<DepartmentsItems> departments;}

第三课

public class DepartmentsItems {
public int pk;
public int fk_hospital;
public String department_slug;
public String department_en;
public String department_ar;
public String desc_en;
public String desc_ar;
public String hospital_en;
public String hospital_ar;
public String hospital_slug;
public int sub_departments_count;
public List<SubDepartments> sub_departments;}

这里混淆了第四类

public class SubDepartments {
public int pk;
public int fk_hospital;
public int fk_department;
public String sub_department_slug;
public String sub_department_en;
public String sub_department_ar;
public String sub_desc_en;
public String sub_desc_ar;
public String hospital_en;
public String hospital_ar;
public String department_en;
public String department_ar;}

在Gson中， SubDepartments 数组中有另一个数组。但是它的名字是0所以我在这里很困惑。如果它很冗长，请建议我任何其他最好的想法。

Answer 1

既然你有两个

"sub_departments": {
      "2": [

和

"sub_departments": [],

默认情况下，只能使用Gson成功解析对象。您可以尝试使用一些自定义反序列化器来检测JSON对象并将其转换为数组，如果这是您需要的。我不确定我可以给出一个例子，但Gson文档有一个关于自定义反序列化器的部分。

但是，您的数据似乎不正确，因为2似乎没有映射到任何内容，并且它不是任何其他部门的“索引”

如果数组在数组中，如何映射gson值
