Question

i have a problem with the timerTask in android i have a code like this:

timer = new Timer();
timer.schedule(new TimerTask() {
        public void run() {
            countInt = countInt + 1;
            textview1.setText(countInt);
        }
    }, 1000);

every time the timer task get startet my app crashed, i thing because i’m accessing the textview and it is in a other thread right?

how to solve this?

Answer 1

try this..

 timer = new Timer();
    timer.schedule(new TimerTask() {
            public void run() {
                countInt = countInt + 1;
                yourActivity.this.runOnUiThread(new Runnable()
               public void run(){
                  {textview1.setText(String.valueOf(countInt))});
                }
            }
        }, 1000);

It crashes because you are messing with something ( textview1.setText(countInt);) that belongs UI thread which is not allowed…
