Observable<List<T>> query(Specification specification);

因此,当我使用Realm并想要检索结果“asObservable”时,我得到了Observable>.我找不到改变Observable的方法>进入Observable>.

任何人都可以帮忙解决这个问题吗？

我试过这样的事

final Observable<RealmResults<PlantRealm>> realmResults = realm.where(PlantRealm.class)
               .equalTo(PlantTable.ID,"1")
               .findAll().asObservable();

// convert Observable<RealmResults<PlantRealm>> into Observable<List<PlantRealm>>

    return realmResults.flatMap(Observable::from).toList().map(list -> {

                for (PlantRealm plantRealm : list) {
                    plants.add(toPlant.map(plantRealm));
                }
                return Observable.from(plants);
            }
    );

但类型检查系统仍在抱怨….

return Observable.create( subscriber -> {

       final Realm realm = Realm.getInstance(realmConfiguration);
       final RealmResults<PlantRealm> realmResults = realm.where(PlantRealm.class)
               .equalTo(PlantTable.ID,"1")
               .findAll();

       final List<Plant> plants = new ArrayList<>();

       for (PlantRealm plantRealm : realmResults) {
           plants.add(toPlant.map(plantRealm));
       }

       realm.close();

       subscriber.onNext(plants);
       subscriber.onCompleted();
   });
