按大小、日期、名称等在回收器视图中排序并记住选择

我正在制作图库应用程序，我想为其添加排序功能，我可以使用以下命令在运行时对项目进行排序Comparator但问题是，每当我退出应用程序时，列表都会再次从数据库中出来，并且所有列表都未排序，我想在我的应用程序中提供按日期、大小、名称等排序的选项，你们能帮助我如何查看这个并记住用户的选择吗？他下次运行该应用程序时，我还阅读了有关排序列表的内容，请告诉我我的问题的解决方案或当前的任何示例代码，我正在这样做以对项目进行排序

public static final Comparator<MediaFileObject> byName=new Comparator<MediaFileObject>() {
    @Override
    public int compare(MediaFileObject o1, MediaFileObject o2) {

        return o1.getAddedDate().compareTo(o2.getAddedDate());
    }
};

我在我的片段中称之为

Collections.sort(list,MediaFileObject.byName);
galleryAdapter.notifyDataSetChanged()

这工作正常，但我想记住用户排序选择请有人帮助我该怎么办？ 我可以通过使用来实现这一点吗SortedList？或任何示例代码请

这可以帮助您根据名称和日期对列表进行排序。

if (theArrayList.size() > 0) {
            if (myUserSelectedSortedType == SORT_BY_NAME) {
                sortListByName(theArrayList);
            } else if (myUserSelectedSortedType == SORT_BY__DATE) {
                sortListByDate(theArrayList);
            }


            myAdapter = new Adapter(MainActivity.this, theArrayList);
            myListView.setAdapter(myAdapter);
        }
