如何使用外部按钮从ScheduledExecutorService中删除任务？

Question

我有一个ScheduledExecutorService

public void pulsor1(Integer interval) {
    Runnable runnable = new Runnable() {
        public void run() {
            flagPulsor1 = true;
            indexPulsor1++;
        }
    };
    scheduleTaskExecutor1 = Executors.newScheduledThreadPool(5);
    scheduleTaskExecutor1.scheduleAtFixedRate(runnable,0,interval,TimeUnit.MILLISECONDS);
}

我想通过点击按钮或像

这样的处理程序来杀死它

handler.sendEmptyMessage(0);

有办法做到这一点吗？
