如何有效地取消定期的ScheduledExecutorService任务

我建议您使用int并自己安排任务。

executor.schedule(new RequestProgressRunnable(), 5000, TimeUnit.MILLISECONDS);class RequestProgressRunnable implements Runnable {    private int count = 0;    public void run() {        // do stuff        // Increment progress value        progressValue += 10;        // Check progress value        if (progressValue < 100) executor.schedule(this, 5000, TimeUnit.MILLISECONDS);    }}
