问题 I'm new to RxAndroid and trying to chain responses. I'm using this github API to retrieve data. Along with each issue there are comments link and events link associated with it which I want to fetch and update existing object with list of comments and events to form something like this. [ issue: { comments: [ { . . }, { . . } ] events : [ { . . }, { . . } ] ] ] I could retrieve initial response with following code GitHubService gitHubService = ServiceFactory.createServiceFrom(GitHubService

问题 I am fairly new in RxJava pradigm. I am doing following is leading to nested Single objects. tickHappened.map{ func(it) } //I get Single<Single<ArrayList<String>>> Here tickHappened:Single<T> and func<T>(T param):Single<ArrayList<String>> tickHappened.map{ func(it) } //I get Single<Single<ArrayList<String>>> .map { single -> single.map { list -> list.size } } I actually need to return Single<Int> which is the size of the Arraylist passed. I need to use map twice in the above chain which leads

问题 I am new to TDD. Also new to MVP and Rxjava. I just dive into it and It is worth it. But I stuck at the testing part. I understand the basis of unit testing. It is a little bit difficult for me in beginning. But I stuck here and So how can test the presenter? Here is the Presenter class - public class NewsPresenter { private final RxjavaService service; private final MainView view; private CompositeSubscription subscriptions; public NewsPresenter(RxjavaService service, MainView view) { this

问题 This question already has answers here : The result of subscribe is not used (6 answers) Closed 9 months ago . I want to do something after short delay: public void notifyMe() { Single .timer(500, TimeUnit.MILLISECONDS) .subscribeOn(Schedulers.io()) .subscribe(ignore -> service.notifyMe())); } Now I have a warning: "The result of subscribe is not used" . How can I fix it? 回答1: A Single will only call once. Upon calling either method, the Single terminates and the subscription to it ends. Link

问题 I am trying to convert examples from this article from Java to Kotlin. I get error from picture at Exmaple 5: And I noticed, that without map() function I don't get this error So, what the point of this error and how to write it right? 回答1: The return value of a lambda in Kotlin is always the last expression in the block. So in this case the result of .map { it.note = it.note.toUpperCase() } is not returning a meaningful value. What you should do instead is this .map { it.note = it.note

In this way, I created a method which take a final parameter (the object I want to save) and returns an Observable. At this point I don't care to emit anything so I will call subscriber.onComplete() at the end. Here is my code: public Observable saveEventLog(@NonNull final EventLog eventLog) { return Observable.create(new Observable.OnSubscribe<Object>() { @Override public void call
