Android - Update Progress Bar with RxJava

[Anh Vinh Huỳnh]

I have a problem to update progress for ProgressBar with RxJava on Android. I want to update 1%after delay 500 miliseconds (from 0% -> 50%) with RxJava. But when I code such as (code in below), progress update to 50% after delay 500 miliseconds.

Below is my code :

Observable.range(0,50)
    .subscribeOn(Schedulers.computation())
    .delay(1000, TimeUnit.MILLISECONDS)
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(integer -> mProgressBar.setProgress(integer));

Please help me with this problem.

Thanks very much.
