【中文标题】在android中保存该数据的最合适方法是啥【英文标题】：What is the most suitable way to save that data in android在android中保存该数据的最合适方法是什么 【发布时间】：2015-08-28 14:39:30 【问题描述】：

我正在制作一个应用程序，它会询问用户他的教师、部门和年级，然后显示科目列表。

问题是保存主题的最佳方法是什么，以便于检索它们并将它们显示给用户。

我尝试了 XML，但它不起作用，现在我尝试了 JSON，但不确定它是否是存储此类数据的最佳方式？

回答：

正如所有人所说，最好的方法是将数据保存在 SQLite 数据库中。

这是我的 JSON 快照

【问题讨论】：

我会将它们保存在数据库中。如果您需要教程：vogella.com/tutorials/androidSQLite/article.html 我正在考虑将它们保存在 SQLite 数据库中，但我认为对于这种简单的情况来说它会过于复杂。 【参考方案1】：

如果要查询的数据不在远程服务器上，则可以使用Android sqlite数据库来保存和获取数据。

【讨论】：

【参考方案2】：

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

JSON 和 XML 更可能用于传输数据，例如使用网络。

【参考方案3】：

您可以使用https://realm.io/，它兼容 Android 和 ios。更简单快捷。

希望对你有帮助。
