领域-使用IN查询RealList

Question

尽管

filteredPosts的记录具有类别3,5

，但在 in 查询中，其大小始终为零

public class Post extends RealmObject{
    @PrimaryKey
    private long id;
    private String title;
    private RealmList<Integer> categories;
}

realm = Realm.getDefaultInstance();
realm.beginTransaction();
Integer cates[] = {3,5};
RealmResults<Post> filteredPosts = 
realm.where(Post.class).in("categories",cates).findAll();
realm.commitTransaction();

Log.e(TAG,filteredPosts.size()+"");
