什么是最合适的方式来保存在android的数据

问题描述：

我正在做一个应用程序，将要求用户的教师，部门和成绩，然后显示主题列表。什么是最合适的方式来保存在android的数据

问题是保存主题的最佳方式是什么，它可以很容易地检索并显示给用户。

我试过XML，但它不起作用，现在我试过JSON，但不知道它是否是存储这种数据的最佳方式？

答：

，因为所有的人说，最好的办法就是保存SQLite数据库中的数据。

这里是我的JSON的卡扣

我会将它们保存在数据库中。 – BackSlash

只是使用SQLite – CantThinkOfAnything

答

如果要查询的数据不是一个远程服务器，那么你可以使用Android的SQLite数据库来保存和获取数据上。

答

也许你应该使用SQLite数据库： https://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html

JSON和XML更可能被用于使用网络，例如传输数据。

答

您可以使用https://realm.io/它在Android和iOS之间兼容。它更简单快捷。

希望它有帮助。

答

如果你想离线存储然后去SQLite。

如果您想要云存储，然后转到Google Firebase，因为它提供了很好的实现抽象，相当数量的存储和同时连接。
