问题描述

我必须每2秒重复一部分代码，我该怎么做？不要告诉我使用
试试{
Thread.sleep（millisecondi）;
}
catch（例外e）{}

I have to repeat a part of my code every 2 seconds how could I do that? don't tell me to use try { Thread.sleep(millisecondi); } catch (Exception e) {}

因为冻结了应用程序

推荐答案

如果您的应用程序要保持响应，则需要在另一个线程中执行此操作。或者您只需创建一个计时器和计划它。

If your application is to stay responsive you need to do this in another thread. Or you could simply create a timer and schedule it.

当你告诉它睡觉时，你所处的线程是什么 - 无可挑剔地这样做......

Whatever thread you're in when you tell it to sleep - will impeccably do so...

这样的事情：

Timer timer = new Timer();
TimerTask myTask = new TimerTask() {
    @Override
    public void run() {
        // whatever you need to do every 2 seconds
    }
};

timer.schedule(myTask, 2000, 2000);
