This is a simple rxjava2/rxjava3/kotlin-flow timer. I copy this class into all the little apps I make. I'm tired of doing it. Now it's a library
Usage
timer = Rx2Timer.builder()
.initialDelay(0) //default is 0
.period(1) //default is 1
.take(30) //default is 60
.unit(TimeUnit.SECONDS) // default is TimeUnit.SECONDS
.onEmit(count -> {
if (count < 10) {
binding.text.setText("0" + count + " s");
} else {
binding.text.setText(count + " s");
}
})
.onError(e -> binding.text.setText(R.string.count))
.onComplete(() -> binding.text.setText(R.string.count))
.build();
timer.start();
timer.stop();
timer.restart();
timer.pause();
timer.resume();
