How to stop a timer after certain number of times

android, timer, timertask

Solution

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);
}

Problem

Trying to use a `Timer` to do run this 4 times with intervals of 10 seconds each. I have tried stopping it with a loop, but it keeps crashing. Have tried using the `schedule()` with three parameters, but I didn't know where to implement a counter variable. Any ideas? ``` final Handler handler = new Handler(); Timer timer2 = new Timer(); TimerTask testing = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { Toast.makeText(MainActivity.this, "test", Toast.LENGTH_SHORT).show(); } }); } }; int DELAY = 10000; for (int i = 0; i != 2 ;i++) { timer2.schedule(testing, DELAY); timer2.cancel(); timer2.purge(); } ```
