我目前正在尝试制作带有菜单的游戏.
菜单看起来像这样.

理想情况下,当我按下按钮时,它将带我进入游戏.
游戏看起来像这样.

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JPanels).

我将如何使用CardLayout进行创建,以便可以初始化游戏菜单,并在单击按钮时将面板更改为游戏面板？

解决方法:

我为您提供了一些示例代码,虽然它并不完美,但是应该可以使用.基本上,您想在布局管理器上使用NEXT或PREVIOUS调用.

因为只有两个面板,所以我仅使用NEXT调用来循环浏览它们.虽然您可以阅读Swing文档,但这可能是最好的选择,但可以满足其他要求.
