Usage

Initate

        progressAnimation = LazyCountAnimation.Builder(
            beginNumber = 0,
            targetNumber = 100
        )
            .setCanCountdown(true)
            .setGranularity(3)
            .setFps(30)
            .doOnNextNumber {
                view.text = "$it"
            }
            .build()

Set target number

progressAnimation.setTargetNumber(77)

Set the next target number, you don't need to do extra works. Lazy count will animate to the next number upon previous number.

progressAnimation.setTargetNumber(86)

Set a negative number, you have to enable the countdown when initiating

progressAnimation.setTargetNumber(-186)

Stop

progressAnimation.stop()

Start

progressAnimation.start()

Callback, here is a returned current number

progressAnimation.doOnNextNumber{ currentNumber ->
    // update a TextView or do something...
    view.text = currentNumber.toString()
}

Set FPS

progressAnimation.setFps(30)
