我有以下RealmObject:

public class City extends RealmObject {
    private String cityId;
    private RealmList<Street> streets;

    public String getId() {
        return cityId;
    }

    public void setCityId(String cityId) {
        this.cityId = cityId;
    }

    public RealmList<Street> getStreets() {
        return streets;
    }

    public void setStreets(RealmList<Street> streets) {
        this.streets = streets;
    }
}

现在有一个城市我需要查询特定城市的街道.怎么做？我做的尝试是:

    Realm.getInstance(context).where(City.class).equalTo("cityId", someCityId, false)
         .findFirst().getStreets().where().findAll()

但这导致了一个例外.我需要在显示的街道ListView实施过滤,所以我需要街道要RealmResults使用RealmBaseAdapter<Street>.
