Java 用户界面设计 求界面代码
一: 首先弄清题目的意思
A.需要的主要组件列表:
1. 创建一个窗口,窗口标题叫Information
2. 3个标签, 用于显示文字 Name Number Class
3. 3个文本框, 用于填写信息
4. 1个按钮, 文字是确认
5. 1个文本域
B.业务逻辑
1. 当点击按钮确认的时候, 把 文本框的信息显示到文本域
C.设计的主要技术
JLabel , JButton, JTextField ...等, 都是swing的组件 , 所以应该使用swing进行创建
二: 确定使用的布局
swing虽然重写了大部分的组件, 但是布局, 依旧沿袭awt技术
分析图片上的布局:
至少有2种方法可以实现,
方法一: 绝对布局 , 优点: 配合可视化GUI拖曳, 可以完美的实现图上的组件的位置
但是缺点也是致命的, 不同的操作系统平台下, 可能会出现位置的移动,
只适合开发平台, 移植效果差 . 所以不推荐使用
方法二: 灵活的表格布局, 配合流式布局 , 所有操作系统下,显示效果都比较统一.
三: 效果图
四: 参考代码
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class FrameDemo extends JFrame {
//申明需要的组件
private final JTextField jtf1,jtf2,jtf3;
private final JTextArea jta;
public FrameDemo() {
setTitle("Information");//设置窗口标题
setSize(320, 360);//设置窗口大小
setLocationRelativeTo(null);//设置窗口居中
setDefaultCloseOperation(EXIT_ON_CLOSE);//设置关闭时退出虚拟机
getContentPane().setLayout(new FlowLayout());//设置窗口布局为流式布局
JPanel jp = new JPanel(new GridLayout(4, 2));//设置jp面板为表格布局4行2列
//第一行
JPanel jp01 = new JPanel();
JLabel jl1 = new JLabel("Name:");
jp01.add(jl1);
JPanel jp1 = new JPanel();
jtf1 = new JTextField(8);
jp1.add(jtf1);
//第二行
JPanel jp02 = new JPanel();
JLabel jl2 = new JLabel("Number:");
jp02.add(jl2);
JPanel jp2 = new JPanel();
jtf2 = new JTextField(8);
jp2.add(jtf2);
//第三行
JPanel jp03 = new JPanel();
JLabel jl3 = new JLabel("Class:");
jp03.add(jl3);
JPanel jp3 = new JPanel();
jtf3 = new JTextField(8);
jp3.add(jtf3);
//第四行
JPanel jp04 = new JPanel();
JLabel jl4 = new JLabel("");
jp04.add(jl4);
JPanel jp4 = new JPanel();
JButton jb = new JButton("确认");
jp4.add(jb);
jp.add(jp01);
jp.add(jp1);
jp.add(jp02);
jp.add(jp2);
jp.add(jp03);
jp.add(jp3);
jp.add(jp04);
jp.add(jp4);
getContentPane().add(jp);
jta = new JTextArea();
jta.setColumns(20);//设置文本域的大小
jta.setEditable(false);//设置文本域不可编辑
jta.setBackground(jp.getBackground());//设置文本域的背景色和面板一样
getContentPane().add(jta);
jb.addActionListener(new ActionListener() {//给按钮添加事件
public void actionPerformed(ActionEvent e) {//点击按钮,显示信息到文本域
String name = jtf1.getText();
String number = jtf2.getText();
String clazz = jtf3.getText();
jta.setText("You name is "+name+" number is "+number+" class is "+clazz);
}
});
}
public static void main(String[] args) {
new FrameDemo().setVisible(true);//创建窗口,被设置为可见
}
}
五: 拓展
虽然图形界面的实现方法是多样的, 我们一定要根据具体情况, 选择一个比较优化的 合理的, 符合业务逻辑的实现方法
