CardLayout.show(parent,name)中parent必须是使用这个layout的主件:
这个是其代码:
void checkLayout(Container parent) {
if (parent.getLayout() != this) {
throw new IllegalArgumentException("wrong parent for CardLayout");
}
}可以看出为什么你上面会出错，另外你的逻辑有问题，如这种代码:
if (e.getSource()==b3) //切换到磁带界面
{ ca.show(p33,"磁带卡片");
cb.show(p20,"磁带");
if(e.getSource()==b4)//添加
{

str1=tf13.getText()+" "+tf14.getText()+" "+tf15.getText()+" "+tf16.getText()+" "+tf17.getText()+" "+tf18.getText();
ls3.add(str3);
}
其中e.getSource都已经等于b3了，还怎么有可能等于b3呢。

你给的代码也太长了吧
这里没有闲人啊
