rx-android

问题 I am having trouble working out how to handle a response error with retrofit and RxAndroid. onError() gets called if there is a network error or the like but I need to be able to get the response to check if there was an authentication error. Instead what I get is a token with a null String and I can't find out why. What is the best way to go about this? This is my RxAndroid call at the moment. Client.getInstance().getService() .getToken(usernameET.getText().toString(), passwordET.getText()

问题 I'm using Retrofit to get bookmarks from REST API: public interface BookmarkService { @GET("/bookmarks") Observable<List<Bookmark>> bookmarks(); } Now I would like to emit each item from this list with delay. I did something similar to this in Java, but onCompleted is never triggered. private Observable<Bookmark> getBookmarks() { return getBookmarkService().bookmarks() .flatMap(new Func1<List<Bookmark>, Observable<Bookmark>>() { @Override public Observable<Bookmark> call(List<Bookmark>

问题 I am trying to filter the list on the basis of it's property. For example, Sensors class has a property isActive and I want to get all the objects with isActive as true but I am unable to do it. I tried different ways but I didn't find the solution. Can someone help me to do it? Here is my code: mCompositeDisposable.add( fcService.getStationList() .subscribeOn(Schedulers.io()) .flatMap( stations -> { return fcService.getSensorList(stations.get(0).getName().getOriginal()); }) .subscribe(this:

问题 I'm getting reports of a NetworkOnMainThread exception on Lollipop+ when running an https api call using Retrofit and RxAndroid . I have isolated the code and created the following example that still fails. Here's the build.gradle : apply plugin: 'com.android.application' apply plugin: 'me.tatarka.retrolambda' android { compileSdkVersion 23 buildToolsVersion "23.0.1" defaultConfig { applicationId "com.example.bug" minSdkVersion 9 targetSdkVersion 23 versionCode 1 versionName "1.0" }

问题 I'm trying to filter a List with RxJava2 such that each item (object) in the list should pass a validation check and I get a resulting List with only items that pass that test. For instance if my Object had the following structure, class MyClassA { int value1; int value2; } I want to only get the list of items where the value2 is 10. I have an API call function that returns an Observable of List, i.e. Observable<List<MyClassA>> as follows, apiService.getListObservable() .subscribeOn

问题 I have a simple use case where: Activity1 create a fragment1 fragment1 after creation notify to activity that it is created and update its activity1 views. activity1 after getting notification update fragment1 views. I am using rxandroid , sublibrary rxlifecycle components and android , but i am still in learning phase , there was not even rx-lifecycle tag on stackoverflow , so i am still struggling to understand the flow of this library.. Edit I prefer not to use EventBus , it's just like

问题 can someone explain me why code like this: networApi.getList() .subscribeOn(Schedulers.newThread()) .observeOn(AndroidSchedulers.mainThread()) .doOnError(throwable -> { throwable.getMessage(); }) .doOnNext(list -> { coursesView.populateRecyclerView(list); courseList = (List<Course>) courses; }).subscribe(); If there is no internet goes into doOnError but throws it further so the app goes down, but code like this: networkApi.getList() .subscribeOn(Schedulers.newThread()) .observeOn

问题 As an example to getting started with RxAndroid I'm trying to implement a searchbox which triggers a rest call when the users inserts something. So far I have two working parts. The first observing the EditTextView ... RxTextView.textChangeEvents(searchEditText) .debounce(400, TimeUnit.MILLISECONDS) .observeOn(AndroidSchedulers.mainThread()) .subscribe(new Observer<TextViewTextChangeEvent>() { @Override public void onCompleted() { Timber.d("onCompleted"); } @Override public void onError

问题 I'm trying to get the latest value of a given Observable and get it to emit immediately once it's called. Given the code below as an example: return Observable.just(myObservable.last()) .flatMap(myObservable1 -> { return myObservable1; }) .map(o -> o.x) // Here I want to end up with a T object instead of Observable<T> object This does not work because by doing this the flatMap will emit myObservable1 which in turn will have to emit to reach the map . I don't know if doing such thing is even

问题 I'm using retrofit 2 with rx-android I have quite complex retry logic, which partially works . I cut off irrelevant code to simplify it. Here it is: public class RetryWithDelay implements Func1<Observable<? extends Throwable>, Observable<?>>, Constants { @Override public Observable<?> call(Observable<? extends Throwable> attempts) { return attempts.flatMap(new Func1<Throwable, Observable<?>>() { @Override public Observable<?> call(Throwable throwable) { int statusCode = 500; if (throwable
