[android help] How to stop the timer after certain time?

java - How to stop the timer after certain time? - Stack Overflow




















I have an android application which has a timer to run a task:



time2.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
sendSamples();
}
}, sampling_interval, sending_interval);


let's say sampling_interval is 2000 and sending_interval is 4000. So in this application I send some reading values from a sensor to the server. But I want to stop the sending after 10000 (10 seconds) what should I do?


























Check this code:



private final static int DELAY = 10000;
private final Handler handler = new Handler();
private final Timer timer = new Timer();
private final TimerTask task = new TimerTask() {
private int counter = 0;
public void run() {
handler.post(new Runnable() {
public void run() {
Toast.makeText(MainActivity.this, "test", Toast.LENGTH_SHORT).show();
}
});
if(++counter == 4) {
timer.cancel();
}
}
};

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
timer.schedule(task, DELAY, DELAY);
}






















try



time2.scheduleAtFixedRate(new TimerTask() {
long t0 = System.currentTimeMillis();
@Override
public void run() {
if (System.currentTimeMillis() - t0 > 10 * 1000) {
cancel();
} else {
sendSamples();
}
}
...
