What is the equivalent to a JavaScript setInterval/setTimeout in Android/Java?

Question

Can anyone tell me if an equivalent for setInterval/setTimeout exists for Android? Does anybody have any example about how to do it?

Answer 1

The first answer is definitely the correct answer and is what I based this lambda version off of, which is much shorter in syntax. Since Runnable has only 1 override method "run()", we can use a lambda:

this.m_someBoolFlag = false;
new android.os.Handler().postDelayed(() -> this.m_someBoolFlag = true, 300);

Answer 2

import java.util.Timer;
import java.util.TimerTask;

class Clock {
    private Timer mTimer = new Timer();

    private int mSecondsPassed = 0;
    private TimerTask mTask = new TimerTask() {
        @Override
        public void run() {
            mSecondsPassed++;
            System.out.println("Seconds passed: " + mSecondsPassed);
        }
    };

    private void start() {
        mTimer.scheduleAtFixedRate(mTask, 1000, 1000);
    }

    public static void main(String[] args) {
        Clock c = new Clock();
        c.start();
    }
}

Answer 3

setInterval()

function that repeats itself in every n milliseconds

Javascript

 setInterval(function(){ Console.log("A Kiss every 5 seconds"); }, 5000);

Approximate java Equivalent

new Timer().scheduleAtFixedRate(new TimerTask(){
    @Override
    public void run(){
       Log.i("tag", "A Kiss every 5 seconds");
    }
},0,5000);

setTimeout()

function that works only after n milliseconds

Javascript

setTimeout(function(){ Console.log("A Kiss after 5 seconds"); },5000);

Approximate java Equivalent

new android.os.Handler().postDelayed(
    new Runnable() {
        public void run() {
            Log.i("tag","A Kiss after 5 seconds");
        }
}, 5000);

Answer 4

As always with Android there's lots of ways to do this, but assuming you simply want to run a piece of code a little bit later on the same thread, I use this:

new android.os.Handler().postDelayed(
    new Runnable() {
        public void run() {
            Log.i("tag", "This'll run 300 milliseconds later");
        }
    }, 
300);

.. this is pretty much equivalent to

setTimeout( 
    function() {
        console.log("This will run 300 milliseconds later");
    },
300);
