rx-java

问题 I am writing an android app and using rxjava to handle user input events. Basically what I want to do is, emit when a button is clicked, and then drop subsequent emissions for some period of time afterwards (like a second or two), essentially to prevent having to process multiple clicks of the button. 回答1: I think throttleFirst is what you want: https://github.com/Netflix/RxJava/wiki/Filtering-Observables#wiki-throttlefirst 回答2: For preventing fast clicks i use this code RxView.clicks(your

问题 I'm trying to implement MVVM pattern usingGoogle's android architecture components while using RX Java in NetworkBoundResource . However I'm having a difficult time finding a way to communicate the error response from network call to activity. here is a link to the original github project. I have read this post about "Refactoring google's NetworkBoundResource class to use RxJava instead of LiveData" but still not clear how to actually solve the problem. would appreciate if you could direct me

问题 Google's android architecture components tutorial here has a part that explains how to abstract the logic of getting data over the network. In it, they create an abstract class called NetworkBoundResource using LiveData to create a reactive stream as the basis for all reactive network requests. public abstract class NetworkBoundResource<ResultType, RequestType> { private final AppExecutors appExecutors; private final MediatorLiveData<Resource<ResultType>> result = new MediatorLiveData<>();

问题 public class RxJavaTest { public static void main(String[] args) { Observable.timer(2, TimeUnit.SECONDS).subscribe(new Consumer<Long>() { @Override public void accept(Long aLong) throws Exception { System.out.println("timer: accept " + aLong); } }); } } Why is there no information output from the console after two seconds? 回答1: By default the timer operator is executed in a different Thread (in the computation thread pool) and your main thread is exited just after calling the subscribe and

问题 As Retrofit docs represent Call enqueue method in Retrofit is : Asynchronously send the request and notify callback of its response or if an error occurred talking to the server, creating the request, or processing the response. and Rxjava according to this tutorial is : RxJava and RxAndroid libraries allow us to easily do async processing using principles of functional reactive programming it seems these two have the same approach. What is advantages and disadvantages of each? Which one is

问题 Currently, I am using an EventBus/PubSub architecture/pattern with Scala (and JavaFX) to implement a simple note organizing app (sort of like an Evernote client with some added mind mapping functionality) and I have to say that I really like EventBus over the observer pattern. Here are some EventBus libraries : https://code.google.com/p/guava-libraries/wiki/EventBusExplained http://eventbus.org (currently seems to be down) this is the one I am using in my implementation. http://greenrobot

问题 Given two methods, both which returns a Single , what is the correct way, using Rx , to chain the two method calls together so that one method is called first, and the second once, and only if, the first completes successfully. Ideally, the second method will be able to access the value returned by the first. 回答1: Assuming your methods are like this: static Single<String> method1() { return Single.just("x"); } static Single<String> method2(String in) { return Single.just(in+"y"); } the
