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) {}

因为冻结应用程序

推荐答案

如果您的应用程序要保持响应，您需要在另一个线程中执行此操作.或者您可以简单地创建一个 计时器 和 安排它.

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.

当你告诉它休眠时，无论你处于什么线程 - 都会无可挑剔地这样做......

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

像这样:

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);
