在 android 中保存该数据的最合适方法是什么
What is the most suitable way to save that data in android
我正在制作一个应用程序,它会询问用户他的院系、部门和年级,然后显示科目列表。
问题是保存主题的最佳方式是什么,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?
答案:
as all people say the best way is to save the data in SQLite dataBase.
这是我的 JSON

如果要查询的数据不在远程服务器上,那么可以使用Androidsqlite数据库来保存和获取数据。
也许您应该使用 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。
您可以使用 https://realm.io/,它在 Android 和 iOS 之间兼容。
更简单快捷。
希望对您有所帮助。
如果您想要离线存储,请使用 SQLite。
如果您想要云存储,请选择 Google Firebase,因为它提供了良好的实施抽象、大量存储和并发连接。
