如何使用pojo类在android中的多个列表数组中获取List数组

Question

我得到了api的回应 我必须得到这样的反应：

@SerializedName("AllQuestions")
public List<AllQuestions> AllQuestions;

我有AllQuestion数组，但现在如何进入pojo类中的多列表数组

"AllQuestions": [
                                        [
                                            {
                                                "QuestionID": "1",
                                                    "QuestionText": "What was the name of your elementary/primary school?"
                                            },
                                            {
