How can I do that ?

Here’s a simple static method that uses a Timer to accomplish this. You pass in the amount of times to vibrate and the period between vibrations. The phone will vibrate for 100ms every repeatPeriodSeconds for repeatCount times.

    public static void repeatVibrate(final int repeatCount, int repeatPeriodSeconds)
    {           
        TimerTask task = new TimerTask()
        {
            private int repeats = 0;

            @Override
            public void run()
            {
                ++repeats;
                Alert.startVibrate(100);
                if(repeats >= repeatCount)
                {
                    cancel();
                }                   
            }
        };
        Timer timer = new Timer();
        timer.scheduleAtFixedRate(task, 0, repeatPeriodSeconds * 1000L);
    }
