取消订阅Single的正确方法是什么？

Question

我想在短暂延迟后做点什么：

public void notifyMe() {
Single
       .timer(500, TimeUnit.MILLISECONDS)
       .subscribeOn(Schedulers.io())
       .subscribe(ignore -> service.notifyMe()));
}

现在我有一个警告："The result of subscribe is not used"。 我该如何解决？

Answer 1

A Single will only call once. Upon calling either method, the Single terminates and the subscription to it ends.
