出于明显的原因，我在游戏中实现了MouseListener。用户需要能够单击面板。
问题不在于单击电路板本身，单击重置按钮resetBoard以及鼠标监听器。当我单击按钮时，面板会发生变化，但是在释放单击时，面板会再次发生变化。考虑到我所有的动作都在public void mouseClicked(MouseEvent e)块下，所以我找不到任何地方可以解释为什么在单击和释放时都会发生变化。我有空的mouseReleased，mouseEntered，mouseExited，mousePressed。
基本上，有人可以帮助我理解为什么只有mouseClicked不为空时，同时按下鼠标和按下Up（以相同的动作）同时复位板。
哦，我知道我并不需要所有这些进口，只是我曾经一次使用它们，而我却忘记将它们取出来了，因为我对本期杂志太在意了。
很抱歉，重复的内容以及其中的所有内容。这是我目前知道该怎么做的唯一方法。
谢谢！

最佳答案
不要将MouseListener与JButtons一起使用，而应使用ActionListeners。 button tutorial中对此进行了详细说明，我强烈建议您尽快阅读它们。
我在您的代码中看到的一个主要问题是在这里找到：
public ImageIcon randomizer() {
try {
purpleBlock.setImage(ImageIO.read(new File("purpleBlock.png")));
redBlock.setImage(ImageIO.read(new File("redBlock.png")));
blueBlock.setImage(ImageIO.read(new File("blueBlock.png")));
greenBlock.setImage(ImageIO.read(new File("greenBlock.png")));
} catch (IOException e) {
e.printStackTrace();
}
Random r = new Random();
int rNum = r.nextInt(4);
if(rNum==0) {
return purpleBlock;
} else if(rNum==1) {
return redBlock;
} else if(rNum==2) {
return greenBlock;
} else {
return blueBlock;
}
}
每当调用
randomizer()方法时，您将从文件中重新读取所有色块图像。无需执行此操作，因为已经使用适当的图像创建了ImageIcons，但不仅如此，这还可能会严重降低程序速度。
