推荐答案

您不能重复使用的TimerTask 秒。

你之所以获得 IllegalStateException异常是（最有可能），因为您尝试安排有previously被取消的任务。

The reason why you get IllegalStateException is (most likely) because you try to schedule a task that has previously been canceled.

要去做正确的，即避免了 IllegalStateException异常，你需要创建一个新的的TimerTask 每次要安排它。

To do it properly, i.e. to avoid the IllegalStateException, you need to create a fresh TimerTask each time you want to schedule it.
