Question

我正在尝试使用bundle传递realm对象，并使用Parcel库

这是我的领域模型类。 Album.java

@Parcel
public class Album extends RealmObject implements Serializable {
@PrimaryKey
  public String id;
  public String upc;
  public String albumName;
  public String albumArtUrl;
  public String artistName;
  public String genre_id;
  public String genreName;
  public String price;
  public String releaseYear;
  public int explicit;
  public RealmList<Song> songs = new RealmList<>();
}

这是Song.java。

@Parcel
public class Song extends RealmObject implements Serializable {
  @PrimaryKey
  public String id;
  public String isrc;
  public String songName;
  public String artistName;
  public String album_id;
  public String albumArtUrl;
  public String genre_id;
  public String genreName;
  public String releaseYear;
  public String price;
  public String lyrics;
  public String demo;
  public int explicit;
}

当我尝试以类似的方式传递相册对象时，

b.putParcelable("album", Parcels.wrap(album));

我有这个错误。

Unable to find generated Parcelable class for com.devhousemyanmar.juketrill.models.Album, verify that your class is configured properly and that the Parcelable class com.devhousemyanmar.juketrill.models.Album$$Parcelable is generated by Parceler.

请帮我解决这个问题。

Answer 1

如果您查看文档，则会有专门针对using Parceler的部分。

// All classes that extend RealmObject will have a matching RealmProxy class created
// by the annotation processor. Parceler must be made aware of this class. Note that
// the class is not available until the project has been compiled at least once.
@Parcel(implementations = { PersonRealmProxy.class },
        value = Parcel.Serialization.BEAN, // <-- requires getters/setters if set
        analyze = { Person.class })
public class Person extends RealmObject {
    // ...
}

但值得注意的是，如果您在将implementations = {PersonRealmProxy.class}传递给realm.copyFromRealm(song)之前使用Parcels.wrap()，则无需指定bean。无论如何，如果你想使用字段值而不是@Configuration @EnableMongoRepositories("com.food.repository") public class ApplicationConfig { @Value("${spring.data.mongodb.host}") private String mongoHost; @Value("${spring.data.mongodb.port}") private int mongoPort; @Value("${spring.data.mongodb.database}") private String mongoDB; @Bean public foodService foodService() { MongoOperations operations = new MongoTemplate(new MongoClient(mongoHost,mongoPort), mongoDB); MongoRepositoryFactory factory = new MongoRepositoryFactory(operations); foodRepository foodRepository = factory.getRepository(foodRepository.class); return new foodService(foodRepository); }序列化策略，你还是需要这样做。

此外，您可能需要a RealmList parceler configuration。

无法使用Realm找到生成的Parcelable类
