How to call a function after delay in Kotlin?

Question

As the title, is there any way to call a function after delay (1 second for example) in Kotlin?

Answer 1

Many Ways

1. Using Handler class

Handler().postDelayed({
    TODO("Do something")
    }, 2000)

2. Using Timer class

Timer().schedule(object : TimerTask() {
    override fun run() {
        TODO("Do something")
    }
}, 2000)

Shorter

Timer().schedule(timerTask {
    TODO("Do something")
}, 2000)

Shortest

Timer().schedule(2000) {
    TODO("Do something")
}

3. Using Executors class

Executors.newSingleThreadScheduledExecutor().schedule({
    TODO("Do something")
}, 2, TimeUnit.SECONDS)
