[{“ id”：“ 154”，“ ontime”：“ 2016-03-15”，“ offtime”：“ 2016-04-14”，“ usluga_id”：“ 2”，“ name”：“ 50mpbs”， “ period”：“ 30”，“ cost”：“ 300”}，

{“ id”：“ 152”，“ ontime”：“ 2016-03-15”，“ offtime”：“ 2016-04-14”，“ usluga_id”：“ 4”，“ name”：“ TV60”，“期间“：” 30“，”费用“：” 100“}，

响应为空，我的问题是什么？

Answer 1

您发布的JSON是用户列表，因此，与其创建ServicesArray类进行解析，不如对其进行反序列化，就好像它是User对象列表一样：

  Type type = new TypeToken<Collection<User>>(){}.getType();
  List<User> users = new Gson().fromJson(jsonString,type);

代替：

  List<User> users = new Gson().fromJson(jsonString,User.class);

Answer 2

您有一系列用户。 使用它作为服务回调的返回类型。 阵列映射到改造中的列表。

public class UserList{

private List<User>users;

public UserList(){};

public List<User>getUsers() {
return users;
}

 public void setUsers(List<User>users) {
  this.users= users;
 }
} 

Answer 3

如果所有响应都为json格式，则可以在所有响应上设置GSON Converter

        Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)    
           .addConverterFactory(GsonConverterFactory.create(builder.create()))
            .build();
