How to create a simple countdown timer in Kotlin?

Question

I know how to create a simple countdown timer in Java. But I'd like to create this one in Kotlin.

package android.os;  new CountDownTimer(20000, 1000) {     public void onTick(long millisUntilFinished) {         mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);     }     public void onFinish() {         mTextField.setText("Time's finished!");     } }.start(); 

How can I do it using Kotlin?

Answer 1

You can use Kotlin objects:

val timer = object: CountDownTimer(20000, 1000) {     override fun onTick(millisUntilFinished: Long) {...}      override fun onFinish() {...} } timer.start()
