Keep a reference to the timer somewhere, and use:
在某处保留对计时器的引用，并使用：
timer.cancel();
timer.purge();
to stop whatever it's doing. You could put this code inside the task you're performing with a static intto count the number of times you've gone around, e.g.
停止它正在做的任何事情。您可以将此代码放在您正在执行的任务中，static int以计算您四处走动的次数，例如
private static int count = 0;
public static void run() {
count++;
if (count >= 6) {
timer.cancel();
timer.purge();
return;
}
... perform task here ....
}

Either call cancel()on the Timerif that's all it's doing, or cancel()on the TimerTaskif the timer itself has other tasks which you wish to continue.
无论是通话cancel()的Timer，如果这一切都在做，或者cancel()在TimerTask如果定时器本身有您希望继续其它任务。

You should stop the task that you have scheduled on the timer: Your timer:
您应该停止您在计时器上安排的任务：您的计时器：
Timer t = new Timer();
TimerTask tt = new TimerTask() {
@Override
public void run() {
//do something
};
}
t.schedule(tt,1000,1000);
In order to stop:
为了停止：
tt.cancel();
t.cancel(); //In order to gracefully terminate the timer thread
Notice that just cancelling the timer will not terminate ongoing timertasks.
请注意，仅取消计时器不会终止正在进行的计时器任务。

timer.cancel(); //Terminates this timer,discarding any currently scheduled tasks.
timer.purge(); // Removes all cancelled tasks from this timer's task queue.

Terminate the Timer once after awake at a specific time in milliseconds.
在以毫秒为单位的特定时间唤醒后终止 Timer 一次。
Timer t = new Timer();
t.schedule(new TimerTask() {
@Override
public void run() {
System.out.println(" Run spcific task at given time.");
t.cancel();
}
}, 10000);
