Call a Thread method every x time

  • 772

It's my first time using a thread and I would like to implement it in such a way that it calls a method every x seconds:

    new Thread(new Runnable() {
        public void run() {
            try {
                metodoallamar();
                Thread.sleep(10000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }).start();
java

    The best thing is to use a Timer as mentioned by David Luque, but you can also try to leave a cycle inside the thread and use sleep for the pause in this case while it is executing, that is, the boolean execute in true enters the while executes the method waits 10 seconds and repeat the process.

        new Thread(new Runnable() {
    public void run() {
        try {
            while(ejecutar){
               metodoallamar();
               Thread.sleep(10000);
            }

        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}).start();

  2. You can use a Handler for this purpose, as an example call a method every 10 seconds (10000 milliseconds):

        final long EXECUTION_TIME = 10000;

    handler.postDelayed(new Runnable() {

        @Override
        public void run() {

            //llama método a ejecutarse cada 10 segundos

            handler.postDelayed(this, EXECUTION_TIME);
        }
    }, EXECUTION_TIME);

  3. private Timer temporizador;
private TimerTask tarea;
private Handler handler = new Handler();

private void IniciarTemporizador(){
    temporizador = new Timer();
    tarea = new TimerTask() {
       public void run() {
          handler.post(new Runnable() {
             public void run(){
                //tu código aqui
             }
          });
       }
    };
    temporizador.schedule(tarea, tiempo_delay, tiempo_bucle);
}
