的Java Swing闪烁的按钮序列

Question

我试图做出补救西蒙说喜欢使用游戏秋千（JFrame中/ Jbuttons中/格设置）。目前我无法弄清楚如何获得一系列闪光灯按钮。由于actionPerformed是非静态的，因此我无法通过摆动计时器运行线程。我不知道该怎么办。

我会很感激，如果有人可以拿我的代码一目了然，并提供洞察力。

Answer 1

您可以创建自己的线程（或者更确切地说，一个Runnable）是闪烁的按钮和通话之间，例如睡觉

class FlashThread implements Runnable { 
    private int[] indices; 
    private int sleepTime; 
    ... suitable constructor 
    public void run() { 
     for (int i : indices) { 
      buttonOn(i); 
      Thread.sleep(sleepTime); 
      buttonOff(i); 
      Thread.sleep(sleepTime); 
     } 
    } 
} 

这应该做的伎俩。

或者，你可以创建一个定时器，并添加一个ActionListener它（类似于您正在使用ButtonDisplayListener等做什么），做中闪烁。

顺便说一句，不通过runGame每一次循环中创建一个新的随机对象（）。生成一次（最好作为一个实例变量而不是本地变量），然后多次使用它。随机对象的生成（可能）是昂贵的，并且生成一堆Random对象有些失败了Random类的用途。

正如@Cameron Skinner所建议的那样，example使用javax.swing.Timer来闪烁按钮以进行简单的匹配游戏。 Timer对此尤其方便，因为其动作事件处理程序在事件分派线程上执行。
