android – 列为@ForeignCollectionField ormlite

我有我的模特班

List<String> _photo_array;

因为我可以在String Class上进行anotation,是否可以使用ormLite来保持它？

解决方法:

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

您将不得不创建一个包装String的实体.就像是：

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

然后你的模型类会有这些照片的ForeignCollection.

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

见foreign collection example.
