我目前正在尝试制作带有菜单的游戏。菜单看起来像这样。 http://puu.sh/xGoC
理想情况下，当我按下按钮时，它会带我进入游戏。游戏看起来是这样的。 http://puu.sh/xGoV
我目前在我的主类中初始化一个 JFrame()，它运行菜单类或游戏类（两者都是 JPanel）。
我将如何使用 CardLayout 来制作它，以便我可以初始化游戏菜单，当我单击一个按钮时，将面板更改为游戏面板？

我为你准备了一些示例代码，它并不完美，但它应该可以工作。基本上，您想在布局管理器上使用 NEXT 或 PREVIOUS 调用。
由于只有两个面板，我只使用 NEXT 调用来循环浏览它们。如果您阅读 Swing 文档，这可能是最好的，这可行，但您也可能有其他要求。

不要CardLayout用于那个。
相反，从框架的内容窗格中删除菜单面板并添加游戏面板。
也要记住validate()框架。像这样的东西：
public static final int VIEW_MENU = 0;
public static final int VIEW_GAME = 1;
private static Container content;
...
content = frame.getContentPane();
public static void setView(int view){
if(view == VIEW_MENU){
content.remove(menuPanel);
content.add(gamePanel);
} else {
content.remove(gamePanel);
content.add(menuPanel);
}
frame.validate();
}
在我目前正在处理的程序中，我有一个名为ViewManager的类，它创建每个视图的静态实例并将它们添加到具有对应于常量字段的索引的数组中。我也有字段来跟踪面包屑/返回的先前视图。这可能是重新发明轮子的情况，但它允许你控制它的一切。而且效率很高。
