If your application is to stay responsive you need to do this in another thread. Or you could simply create a timerand scheduleit.
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并安排它。
Whatever thread you're in when you tell it to sleep - will impeccably do so...
当你告诉它睡觉时，无论你处于什么线程 - 都会无可挑剔地这样做......
Something like this:
像这样的东西：
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);
