Java——CardLayout卡片式格局_android eclipse 怎么实现卡片布局-优快云博客

本文介绍了一个使用Java Swing的CardLayout实现卡片式布局的示例程序。通过CardLayout可以轻松地在多个面板之间进行切换，创建类似翻页效果的界面。示例中详细展示了如何创建按钮并为它们添加监听器来控制不同卡片的显示。

CardLayout布局
方法	说明
public void first(Container parent)	翻转到容器的第一张卡片
public void last(Container parent)	翻转到容器的最后一张卡片
public void next(Container parent)	翻转到指定容器的下一张卡片
public void previous(Container parent)	翻转到指定容器的前一张卡片
public void show(Container parent)	翻转到使用addLayoutConmponent 添加到此布局的具有指定的name的组件
