我用

list = new ArrayList<QuestionBean>();

JsonArray array = new JsonParser().parse(jsonString).getAsJsonArray();

for (JsonElement elem : array) {

list.add(new Gson().fromJson(elem, QuestionBean.class));

}

轉化時遇到部分數據為null的問題，困擾了好久，輸出結果如下

bean文件如下

public void setTitlename(String titlename) {

this.titlename = titlename;

}

public String getTitlename() {

return desc;
