Question

java中如何做到界面的跳转？

Answer 1

假如有两个frame,分别为frame1,frame2,frame1加个按钮实现跳转.frame1代码如下
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class frame1 extends JFrame implements ActionListener{

/**
* @param args
*/
private JButton jb;
public frame1()
{
this.setSize(300, 200);
this.setLocation(300, 400);
jb=new JButton("跳转");
this.add(jb);
jb.addActionListener(this);//加入事件监听
this.setVisible(true);

}
public static void main(String[] args) {
// TODO Auto-generated method stub
frame1 frame=new frame1();

}
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
if(e.getSource()==jb)
{
this.dispose();//点击按钮时frame1销毁,new一个frame2
new frame2();
}
}

}

frame2是个单纯的界面
import javax.swing.JButton;
import javax.swing.JFrame;

public class frame2 extends JFrame{

/**
* @param args
*/
public frame2()
{

this.setSize(300, 200);
this.setLocation(300, 400);

this.setVisible(true);
}
public static void main(String[] args) {
// TODO Auto-generated method stub
frame2 frame=new frame2();
}

}
