Android 如何更改数据库帮助程序以支持多种语言？

这是我的dbhelper代码。我想问一下，在这个数据库中是否可以支持多种语言？是否需要使用谷歌翻译api，或者我应该为另一种语言创建另一个数据库

与其创建单独的数据库，不如向表中添加另一列来指示语言，并将本地化字符串存储在同一个表中。

是的，您可以使用相同的数据库SQLite始终将文本数据存储为Unicode，使用创建数据库时指定的Unicode编码。数据库驱动程序本身负责在您的语言/平台使用的编码中以Unicode字符串的形式返回数据

sqlite在内部以UTF-8或UTF-16对所有字符串进行编码（每个数据库都有一个选项），但由于它总是根据需要将它们转换为一个或另一个进行比较，并在API中与java.lang.String进行转换，因此您甚至不必在意

在数据库表中，您可以为不同语言的语言字符串添加不同的列，并仅从该特定列获取数据

---

在应用程序上，您可以为用户提供更改语言的选项。此时，您可以根据所选语言更改列，并仅对该列执行添加/编辑操作。

您有任何这样做的示例吗？这里有一些有用的讨论：好。然后我的下一个问题是如何编写更改数据库语言的代码。对于我的应用程序，用户可以添加/编辑数据库，如果应用程序在运行时，当用户添加新数据时，我不知道如何获取新数据以将其翻译为另一种语言。你的意思是，如果一个用户输入“En”数据，即英语单词，然后，列（英语）将收集数据，用户只能在列（英语）中看到数据？如果用户将“En”语言更改为其他语言，则用户无法看到“En”“其他语言列中的数据？这取决于您的要求。您可以翻译并存储在其他列中，或者只允许用户添加/编辑她/他的语言。您知道翻译数据库中数据的详细信息吗？为什么要翻译数据？正如我在回答中明确提到的，sqlite支持UTF格式来存储数据。您可以在其中存储任何语言字符串。
