android - How do I convert this RxJava observable to emit results every 200 ms? -

-

i have observable:

observable<string> concatenatedsets =             observable.just("1/5/8", "1/9/11/58/16/", "9/15/56/49/21");      concatenatedsets.flatmap(s -> observable.from(s.split("/")))             .map(s -> integer.valueof(s))             .subscribeon(schedulers.computation())             .observeon(androidschedulers.mainthread())             .subscribe(i -> tvcounter.settext(string.valueof(i)));

how convert or operator chain onnext called 200 ms in between calls?

i looking @ question: pause between call onnext in rxjava

but answers there start creating pause using interval so

observable.interval(100, timeunit.milliseconds)

however, creating observable in way (using just), how mix both functionalities (just , interval) or do achieve pause of 200 ms between emissions?

ps: tried delay - postponed overall execution once time provided. zip might answer confusing, how zip observable , interval one?

observable<integer> observable = observable.just("1/5/8", "1/9/11/58/16/", "9/15/56/49/21")                 .flatmap(s -> observable.from(s.split("/")))                 .map(s -> integer.valueof(s));  observable<integer> zippedobservable = observable.zip(                 observable,                 observable.interval(100, timeunit.milliseconds),                 (number, interval) -> number);  zippedobservable         .subscribeon(schedulers.computation())         .observeon(androidschedulers.mainthread())         .subscribe(i -> tvcounter.settext(string.valueof(i)));
