这是代码：@H_502_1@

@H_502_1@

  mSubscribe = Observable.just(readData())            .delay(DELAY, TimeUnit.SECONDS)            .filter(value -> !value.isEmpty())            .switchIfEmpty(createRequest())            .subscribeOn(Schedulers.io())            .observeOn(AndroIDSchedulers.mainThread()).subscribe(data -> {                getVIEw().hIDeLoading();                writeData(data);            },            (throwable -> {            }));

读数据@H_502_1@

@H_502_1@

  private List<categoryModel> readData() {    Realm defaultInstance = Realm.getDefaultInstance();    List<categoryModel> Title = defaultInstance.where(categoryModel.class).findAllSorted("Title");    defaultInstance.close();    return Title;}

写数据@H_502_1@

@H_502_1@

private voID writeData(List<categoryModel> categoryModels) {        try {            Realm defaultInstance = Realm.getDefaultInstance();            defaultInstance.executeTransactionAsync(realm -> realm.insertOrUpdate(categoryModels));            defaultInstance.close();        } finally {            getVIEw().notifyActivity(categoryModels);        }    }

如何使用正确的线程遵循此逻辑？@H_502_1@

解决方法:@H_502_1@

您只能在事务中 *** 作Realm对象,或者只能在读/写这些对象的线程中 *** 作.在您的情况下,您从readData方法获取RealmResult并使用RxJava切换导致异常的线程.使用copyFromrealm从realm获取数据,它将它们作为普通对象而不是realm对象返回.@H_502_1@ 总结
