Android 中使用Gson进行list集合的序列化与反序列化

Posted 2021-07-11 路宇_

重点：

Type type =new TypeToken<List<Student>>(){
        }.getType();

把type对象直接传入到fromJson中

		List<Student> list = new ArrayList<>();
        list.add(new Student("小张","男",20,"读书"));
        list.add(new Student("小明","男",20,"跑步"));
        list.add(new Student("小红","女",20,"旅游"));
        list.add(new Student("小白","男",20,"唱歌"));

        //将list集合序列化
        String s = new Gson().toJson(list);
        System.out.println("序列化为："+s);

        //将list集合反序列化
        Type type =new TypeToken<List<Student>>(){
        }.getType();
        List<Student> list1 = new Gson().fromJson(s,type);
        System.out.println(list1.get(1).getName());
