问题 I want to send array objects with multipart data. I tried many ways but it is not working. My issue with the contributor parameter. Server says. contributor.0.id is required & contributor.0.role is required and so on for remaining items in the list. Server reads that there is a contributor array and it has items but he can't extract it for some reason. Any help please? @Multipart @POST("project/create") fun createProject( @Header("Authorization") token: String, @Part("title") title: String,

问题 I use combineLatest() to combine 3 streams of observables. All these are combined so that all data in the UI is shown at the same time. Now, there is a scenario in which one of the observables won't emit anything, since the data that gets fetched, can be null. Is there a RxJava operator to let the subscriber know that there won't be any emits because of null data? Edit private fun retrieveData() { Observable.combineLatest(getCurrentUser.execute(), getLatestGoal.execute(), getLatestLog.execute

问题 I have the following single letter stream A B C A D B A C D And from this stream, I would like a stream of running count per letter (A,1) (A,1), (B,1) (A,1), (B,1), (C,1) (A,2), (B,1), (C,1) (A,2), (B,1), (C,1), (D,1) (A,2), (B,2), (C,1), (D,1) (A,3), (B,2), (C,1), (D,1) (A,3), (B,2), (C,2), (D,1) (A,3), (B,2), (C,2), (D,2) , i.e at each new letter, the totals are updated and emitted. I guess this problem is fairly language agnostic, so don't hesitate to propose a solution in your language of

问题 I have a test project with Room database. Using Asynctask I can successfully insert an object with some test data into the database. I'm trying to learn RxJava and replace Asynctask with RxJava's observer , but it doesn't work. I have read alot of documentation and watched tutorials, but I don't think I quite get it. Here's the relevant code: Here I set my Room object with the data from my List : for(ObjectForArray item: listToDatabase) { myRoomEntity.setName( item.getName() ); Log.d( "TAG",

问题 I have a method where based on Flowable data value I need to continue RX chain different ways . what I mean is that if the isOnline property of data object is true then I need to call scan(initial,selector) but if it is false then I need to call scan(selector) @NotNull public Flowable<Data> initialCall( @NotNull Flowable<Info> info, Data initial) { return info .map() .switchMap(it -> call(Flowable.just(it),initial, it.isOnline)); } private Flowable<Data> call ( Flowable<A> a, Data initial,

问题 I am using grpc-java and have 3 services, A, B and C. I call service A and then service A calls B and C. I am using Hystrix in the calls to B and C. C in turn spawns another thread to call another service. I have ClientInterceptors and ServerInterceptors which passes around the traceId. I can see the traceIds in the Context and logs as long as it is a gRPC worker thread but lose them when the call moves to another thread - RxIoScheduler thread or Hystrix thread. How do I pass the traceId
