How to stop and resume Observable.interval emiting ticks

Question

This will emit a tick every 5 seconds.

Observable.interval(5, TimeUnit.SECONDS, Schedulers.io())
            .subscribe(tick -> Log.d(TAG, "tick = &qu         


        

Answer 1

val switch = new java.util.concurrent.atomic.AtomicBoolean(true)
val tick = new java.util.concurrent.atomic.AtomicLong(0L)

val suspendableObservable = 
  Observable.
    interval(5 seconds).
    takeWhile(_ => switch.get()).
    repeat.
    map(_ => tick.incrementAndGet())

You can set switch to false to suspend the ticking and true to resume it.
