Question

I have 4 int for time

int delay;
int period;
int delay1;
int period1;

they are taking control of these methods:

cameraOn();
    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new TimerTask() {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            cameraOff();
        }
    },delay1,period1);



    Timer timer2 = new Timer();
    timer2.scheduleAtFixedRate(new TimerTask() {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            cameraOn();
        }
    },delay,period);

        }

These methods are doing the flash camera blink all the time, and what I want is with two buttons I have, change the speed of the blink, now they’re like this:

case R.id.btslow:
        delay = 2400;
        period = 2400;
        delay1 = 1200;
        period1 = 2400;
        break;

    case R.id.btfast:
        delay = 600;
        period = 600;
        delay1 = 300;
        period1 = 600;
        break;

but they dont change the speed of the blink, how can I do it? Because if give them some valor from the begining later they don’t change when I press the buttons. Thanks!!

Changing the variables won’t change the interval and delay of the current scheduled tasks, try this: https://stackoverflow.com/a/3871723/1333516
