暂停执行中的Java GUI [英] Pause execution in Java GUI

问题描述

我写了Android测验程序（Java编写的）。当用户回答一个问题（点击一个按钮），我想换一个消息屏幕说他们是否正确与否，其次是5秒的暂停在转移到下一个问题之前。

I am writing a quiz program for the Android (written in Java). When the user answers a question (by clicking a button), I want to flash a message on the screen saying whether they were correct or not, followed by a 5 second pause before moving on to the next question.

然而，当点击一个答案按钮时，程序将暂停，但不显示正确/不正确的消息。一旦睡眠方法完成了消息仅出现。

However, when an answer button is clicked, the program pauses, but does not display the message of correct/incorrect. The message only comes up once the sleep method has finished.

if (correct)   
    Answer.setText("CORRECT!"); 
else 
    Answer.setText("WRONG!"); 

try { Thread.sleep(5000); } 
catch(InterruptedException e) {}

在暂停期间禁用

作为奖励，我想答案按钮。

As a bonus, I'd like the answer buttons to be disabled during the pause.

推荐答案

伊莫的AsyncTask 是太多这个用例。

Imo AsyncTask is too much for this usecase.

不要使用睡眠。
相反，设置正确/不正确的消息，比做到这一点：

Don't use sleep. Instead set your correct/incorrect message and than do this:

new Handler().postDelayed(new Runnable(){
  public void run()
  {
    goToNextScreen();
  }
}
, 5000);
