actionPerformed()里如何捕捉回车?

我记得还是用KeyListener来处理输入比较合适

下面的代码片断，你自己看看吧，已知cardNumber是一个TextField类的实例

cardNumber.addActionListener(
new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
cl.show(pc,cardNumber.getText());
}
}
);

[starsoulxp]

public void textField1_KeyPressed(java.awt.event.KeyEvent keyEvent)
{
ivjTextField1.setText("");
ivjTextField1.setText(String.valueOf(keyEvent.getKeyCode()));
}

[starsoulxp]

public void keyReleased(KeyEvent e)
{
char c = e.getKeyChar();
//System.out.println((int)c);
if(((int)c == 0) || ((int)c == 27) || ((int)c == 65535) || (c == KeyEvent.VK_BACK_SPACE) || (c == KeyEvent.VK_DELETE) || (c == KeyEvent.VK_ENTER) || (c == KeyEvent.VK_TAB)|| (c == KeyEvent.VK_SHIFT)|| e.isActionKey())
{
if(c == KeyEvent.VK_BACK_SPACE)
{

}
return;
}
}
