如何在Java中删除/ postDelayed runnables？ [英] How to remove/postDelayed runnables in Java?

问题描述

在一个事件发生时，我想运行一个任务/可运行但是在2秒内延迟它的执行。

Upon an event, I'd like to run a task/runnable but delay it's execution in 2 seconds.

在这2秒内，如果发生同样的事件，我想删除之前的任务并重新发布它 - 再次延迟2秒。

During these 2 seconds, if the same event occurs, I'd like to remove the previous task and re-post it to run - again delayed by 2 seconds.

一个示例场景是后台编译。保存文件时，我等待2秒钟，然后开始编译类和其他类，具体取决于类。我不想一直这样做 - 特别是如果有编辑器自动保存文件，比如IntelliJ IDEA。

An example scenario would be background compilation. When a file is saved, I'm waiting 2 seconds and start compiling the class and other, depending classes. I don't want to do it all the time - especially if there are editors that save files automatically, like IntelliJ IDEA.

那么，如何删除/ postDelayed runnables in Java ，如Android的Handler（删除 / postDelayed ）？

So, how can I remove/postDelayed runnables in Java, like Android's Handler (remove / postDelayed)?

推荐答案

你可以使用 Executors.newScheduledThreadPool 为了安排任务，
你可以按照发布的回答：

you can use the Executors.newScheduledThreadPool in order to schedule the task, and you can follow this post's answer :

BlockingQueue<Runnable> queue = threadPool.getQueue();

以获得排队的runnables。

in order to get the queued runnables.
