I\'m extending the CountDownTimer class to obtain some custom functionality .In onTick() in case some conditions are met I call cancel() , expecting that will be the end of
CountDownTimer is also working fine for me, but I think it only works if you call it OUTSIDE of the CountDownTimer implemetation (that is don't call it in the onTick).
Calling it inside also didn't worked.
I tried this code snippet, since most answers are saying you cannot cancel the timer inside its implementation, thus i tried using a handler inside onFinish. Old post but if anyone comes across this its helpful.
new Handler().post(new Runnable() {
@Override
public void run() {
timerTextView.setText("00:" + String.format("%02d", counter));
cancel();
}
});
CountDownTimer.cancel() method seems to be not working. Here's another thread without a solution Timer does not stop in android.
I would recommend you to use Timer instead. It's much more flexible and can be cancelled at any time. It may be something like that:
public class MainActivity extends Activity {
TextView mTextField;
long elapsed;
final static long INTERVAL=1000;
final static long TIMEOUT=5000;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTextField=(TextView)findViewById(R.id.textview1);
TimerTask task=new TimerTask(){
@Override
public void run() {
elapsed+=INTERVAL;
if(elapsed>=TIMEOUT){
this.cancel();
displayText("finished");
return;
}
//if(some other conditions)
// this.cancel();
displayText("seconds elapsed: " + elapsed / 1000);
}
};
Timer timer = new Timer();
timer.scheduleAtFixedRate(task, INTERVAL, INTERVAL);
}
private void displayText(final String text){
this.runOnUiThread(new Runnable(){
@Override
public void run() {
mTextField.setText(text);
}});
}
}
