In the last statement you are converting the duration to time which also considers the timezone. I assume that your timezone is +530, so 5 hours and 30 minutes gets added to 30 minutes. You can do as given below. var eventTime= 1366549200; // Timestamp – Sun, 21 Apr 2013 13:00:00 GMT var currentTime = … Read more
import java.util.Scanner; import java.util.Timer; import java.util.TimerTask; public class Stopwatch { static int interval; static Timer timer; public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print(“Input seconds => : “); String secs = sc.nextLine(); int delay = 1000; int period = 1000; timer = new Timer(); interval = Integer.parseInt(secs); System.out.println(secs); timer.scheduleAtFixedRate(new TimerTask() { … Read more
I checked the source code of CountDownTimer. The “missing tick” comes from a special feature of CountDownTimer that I have not yet seen being documented elsewhere: At the start of every tick, before onTick() is called, the remaining time until the end of the countdown is calculated. If this time is smaller than the countdown … Read more
Instead of trying to show the remaining time for all, the idea is to update the remaining time for the items which are visible. Please follow the following sample code and let me know : MainActivity : public class MainActivity extends Activity { private ListView lvItems; private List<Product> lstProducts; @Override protected void onCreate(Bundle savedInstanceState) { … Read more
A simple option is to manually keep track of time using millis(). You would use two variables: one to store elapsed time one to store the wait/delay time you need In the draw() method you would check if the difference between the current time (in millis.) and the previously stored time is greater(or equal) to … Read more
Here is an example using Timer.periodic : Countdown starts from 10 to 0 on button click : import ‘dart:async’; […] Timer _timer; int _start = 10; void startTimer() { const oneSec = const Duration(seconds: 1); _timer = new Timer.periodic( oneSec, (Timer timer) { if (_start == 0) { setState(() { timer.cancel(); }); } else { … Read more
You have to setState every second with the seconds remaining (every time the interval is called). Here’s an example: class Example extends React.Component { constructor() { super(); this.state = { time: {}, seconds: 5 }; this.timer = 0; this.startTimer = this.startTimer.bind(this); this.countDown = this.countDown.bind(this); } secondsToTime(secs){ let hours = Math.floor(secs / (60 * 60)); let … Read more
Yes, you understood correctly. CountDownLatch works in latch principle, the main thread will wait until the gate is open. One thread waits for n threads, specified while creating the CountDownLatch. Any thread, usually the main thread of the application, which calls CountDownLatch.await() will wait until count reaches zero or it’s interrupted by another thread. All … Read more
new CountDownTimer(30000, 1000) { public void onTick(long millisUntilFinished) { mTextField.setText(“seconds remaining: ” + millisUntilFinished / 1000); //here you can have your logic to set text to edittext } public void onFinish() { mTextField.setText(“done!”); } }.start(); Refer to this link.
I have two demos, one with jQuery and one without. Neither use date functions and are about as simple as it gets. Demo with vanilla JavaScript function startTimer(duration, display) { var timer = duration, minutes, seconds; setInterval(function () { minutes = parseInt(timer / 60, 10); seconds = parseInt(timer % 60, 10); minutes = minutes < … Read more
