android - 如何使用现有的 Realm 作为资源

Question

我想把一个已经有一些数据的Realm数据库作为只读资源文件放到Android的assets文件夹中，我该怎么办？

Answer 1

根据 https://realm.io/docs/java/latest/#read-only-realms

您可以将the_realm.realm文件放入/assets文件夹

然后你可以像这样构建一个配置(这也使它成为 readOnly())

RealmConfiguration config = new RealmConfiguration.Builder()
    .assetFile("the_realm.realm")
    .readOnly()
    // It is optional, but recommended to create a module that describes the classes
    // found in your bundled file. Otherwise if your app contains other classes
    // than those found in the file, it will crash when opening the Realm as the
    // schema cannot be updated in read-only mode.
    .modules(new BundledRealmModule())
    .build();

然后 BundledRealmModule 就像

@RealmModule(classes={Dog.class, Cat.class})
public class BundledRealmModule {
}
