android - List 作为@ForeignCollectionField ormlite

Question

我的模型类中有

List<String> _photo_array;

因为我可以在 String 类上添加注释，是否可以使用 ormLite 来持久化它？

Answer 1

since I can put anotation on String Class is it a way to persist it using ormLite?

您将必须创建一个包装 String 的实体。像这样的东西:

 @DatabaseTable
 public class Photo {
     @DatabaseField(generatedId = true)
     private int id;
     @DatabaseField
     private String photo;
     @DatabaseField(foreign = true)
     private Model model;
 }

然后您的模型类将有这些照片的 ForeignCollection。

 @DatabaseTable
 public class Model {
     @DatabaseField(generatedId = true)
     private int id;
     @ForeignCollectionField()
     private ForeignCollection<Photo> photos;
 }
