我有CompositeSubscription,在那里我添加了与ReplaySubject的订阅
CompositeSubscription compositeSubscription = new CompositeSubscription();
ReplaySubject subject = ReplaySubject.create();
compositeSubscription.add(
manager.getAllContacts()
.toList()
.doOnNext(new Action1<List<Person>>() {
@Override
public void call(List<Person> persons) {
allPersons = persons;
Log.e(TAG, "BookContacts: " + "allPersons = " + allPersons.size());
setupViewPager();
}
})
.subscribe(subject));
然后我用这个ReplaySubject添加第二个订阅
compositeSubscription.add(Observable.combineLatest(subject,
(PublishSubject<List<CustomUser>>) execute(
manager.getDigitsContacts()),
new Func2<List<Person>, List<CustomUser>, Object>() {
@Override
public Object call(List<Person> persons, List<CustomUser> customUsers) {
//... my code with persons and customUsers...
return null;
}
})
.subscribe());
代码正在运行,之后完成ReplaySubject hasCompleted = true。
但是当我尝试添加第三个订阅时,它不会调用“call()”方法
compositeSubscription.add(Observable.combineLatest(subject,
(PublishSubject<List<CustomUser>>) execute(
manager.getFacebookContacts()), //<-----manager.getFacebookContacts() is run, but doesn't call call() method
new Func2<List<Person>, List<CustomUser>, Object>() {
@Override
public Object call(List<Person> persons, List<CustomUser> customUsers) {
//...this method is not called after "manager.getFacebookContacts()"
return null;
}
})
.subscribeOn(Schedulers.newThread())
.subscribe());
如何解决??因为如果我同时添加订阅它可以正常工作。
答案 0 :(得分:3)
是否可以将错误回调添加到.subscribe()
?我的猜测是第三次,ReplaySubject
溢出了combineLatest的缓冲区。您应该使用.replay().autoConnect(0)
CompositeSubscription compositeSubscription = new CompositeSubscription();
Observable<List<Person>> persons = manager.getAllContacts()
.toList()
.doOnNext(new Action1<List<Person>>() {
@Override
public void call(List<Person> persons) {
allPersons = persons;
Log.e(TAG, "BookContacts: " + "allPersons = " + allPersons.size());
setupViewPager();
}
}).replay().autoConnect(0, s -> compositeSubscription.add(s));
然后使用persons
代替subject
