Convert Observable> to a sequence of Observable in RxJava

Question

Given a list of cars (List cars), I can do:

Observable.just(cars); //returns an Observable that emits one List
Observable.from         


        

Answer 1

You can map an Observable<List<Car>> to Observable<Car> like so:

yourListObservable.flatMapIterable(x -> x)

Note that flatMapping might not preserve the order of the source observable. If the order matters to you, use concatMapIterable. Read here for more details.

Answer 2

you can use this

flatMap { t -> Observable.fromIterable(t) }
