Android: извлечение данных из другого списка объектов с помощью модернизации

Question

Я пытаюсь получить различные типы данных List с помощью Retrofit. Я составил список и поместил в него данные.

Может кто-нибудь подсказать мне, как я могу получить различные типы данных модели? У меня есть Когда я пытался поместить Список объектов в свой список пользовательских моделей, я получил эту ошибку:

java.lang.ClassCastException: com.google.gson.internal.LinkedTreeMap cannot be cast to .....

Класс модели

public class WorkType {

@SerializedName("type")
@Expose
private String type;
@SerializedName("worklist")
@Expose
private List<Object> worklist = null;

/**
 * No args constructor for use in serialization
 * 
 */
public WorkType() {
}

/**
 * 
 * @param worklist
 * @param type
 */
public WorkType(String type, List<Object> worklist) {
    super();
    this.type = type;
    this.worklist = worklist;
}

public String getType() {
    return type;
}

public void setType(String type) {
    this.type = type;
}

public List<Object> getWorkList() {
    return worklist;
}

public void setWorkList(List<Object> worklist) {
    this.worklist = worklist;
}

}

Модифицированный интерфейс

@FormUrlEncoded
@POST("worklist")
Call<ArrayList<WorkType>> worklist(
        @Field("teamid") String teamID
);
