ActionListener和Thread.sleep [英] ActionListener and Thread.sleep

问题描述

我有一个JButton，一旦我点击它，我想在几秒后改变一些颜色，例如从蓝色 - > 1秒 - >红色 - > 1秒 - >黄色。我的问题是，只要我在ActionListener中使用Thread.sleep函数并测试我的程序，它会冻结2秒并直接给我黄色。我该如何解决这个问题？非常感谢

I have a JButton, which, as soon as I click on it, I want to change some colors after a few seconds, for example from blue -> 1 sec -> red -> 1 sec -> yellow. My problem is that, as soon as I use the Thread.sleep function in ActionListener and I test my program, it freezes for the 2 seconds and gives me directly yellow. How can I fix that? Thanks a lot

推荐答案

ActionListener和Thread.sleep ..

ActionListener and Thread.sleep..

..不能很好地一起玩。

..don't play well together.

不要阻止EDT（事件调度线程） - 当发生这种情况时，GUI将冻结。而不是调用 Thread.sleep（n）为重复任务或实现Swing 计时器 SwingWorker 用于长时间运行的任务。有关更多详细信息，请参阅 Swing中的并发。

Don't block the EDT (Event Dispatch Thread) - the GUI will 'freeze' when that happens. Instead of calling Thread.sleep(n) implement a Swing Timer for repeating tasks or a SwingWorker for long running tasks. See Concurrency in Swing for more details.
