Thread.sleep () in while loop with RequestQue

Question

what i'm trying to do is while loop with delay of 15 seconds and inside the loop i want to execute volley request .. the loop is working but with no delay

this is my code : (client2 is the volley request method )

new Thread(new Runnable() {@Override
    public void run() {
        while (h < taxiidlist.size() && assined == false && requested == true) {
            handler2.post(new Runnable() {@Override
                public void run() {

                    client2(user.id, taxiidlist.get(h));

                    h++;
                }

            });
                try {
                    Thread.sleep(15000);
                } catch(InterruptedException e) {
                    e.printStackTrace();
                }

            }
        }
    }).start();

Is it a typo? Your bracing looks off, close brace missing. The try/Thread.sleep block appears inside your new Runnable declaration. But I'm surprised if that's actually the case if that would compile. — David Bradley, Dec 31 '16 at 17:07
Just what I was about to say. The try-catch code should be inside the `run()` method to be executed when your `client2()` is being executed. Wonder how it is working. — Prathap, Dec 31 '16 at 17:10

I don't see why the code isn't working. One possible issue might be that you have forgotten to invoke run() within the handler.post() where your inner Runnable instance is being passed.

Try with this sample code (loop executed just once) and see if you can spot the issue in yours.

private static List<String> taxiidlist = new ArrayList<>();
static int h = 0;

public static void main(String[] args) {

    int id = 0;
    boolean assined = false;
    boolean requested = true;
    taxiidlist.add("One");

    new Thread(new Runnable() {
        @Override
        public void run() {
            while (h <= taxiidlist.size() && assined == false && requested == true) {
                post(new Runnable() {
                    @Override
                    public void run() {
                        client2(id, taxiidlist.get(h));
                        h++;

                        try {
                            Thread.sleep(1500);
                            System.out.println("slept!");
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                });

                break;
            }
        }
    }).start();

}

static void post(Runnable runnable) {
    System.out.println("post!");
    runnable.run();

}

static void client2(int id, String s) {
    System.out.println("client2!");
}

Hope this helps :)

The only change I made was to add code to invoke the inner Runnable with the `run()` method. I have kept everything else as close as I could with yours so that it makes it easier for you to track down the issue. Is your `client2()` being called? — Prathap, Dec 31 '16 at 21:22
