setSize(330,240);
Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
setLocation((screen.width - getSize().width)/2,(screen.height - getSize().height)/2 );
setVisible(true);
setResizable(false);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String args[]){
Demo d = new Demo();
}
}
2. java QQ登陸界面代碼
package com.demo4;
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
import javax.swing.border.EmptyBorder;
public class Demo1 extends JFrame{
public Demo1(){
init();
}
private void init(){
ImageIcon icon=new ImageIcon("Image/8.jpg");
setIconImage(icon.getImage());
setTitle("QQ2011");
setSize(310,270);
setContentPane(createContentPane());
}
private JPanel createContentPane(){
JPanel pane=new JPanel(new BorderLayout());
pane.add(BorderLayout.NORTH,new JLabel(new ImageIcon("Image/5.jpg")));
pane.add(BorderLayout.CENTER,createPane());
pane.add(BorderLayout.SOUTH,createButtonPane());
return pane;
}
private JPanel createPane(){
JPanel pane=new JPanel(new BorderLayout());
pane.setBorder(new EmptyBorder(12,24,12,24));
pane.add(BorderLayout.NORTH,createGridPane());
pane.add(BorderLayout.CENTER,createCheckBoxPane());
return pane;
}
private JPanel createGridPane(){
JPanel pane=new JPanel(new GridLayout(2,1,0,8));
pane.add(createName());
pane.add(createPassword());
return pane;
}
private JPanel createName(){
JPanel pane=new JPanel(new BorderLayout());
pane.add(BorderLayout.WEST,new JLabel("賬號"));
pane.add(BorderLayout.CENTER,new JTextField(10));
pane.add(BorderLayout.EAST,new JButton("清除賬號"));
return pane;
}
private JPanel createPassword(){
JPanel pane=new JPanel(new BorderLayout());
pane.add(BorderLayout.WEST,new JLabel("密碼"));
pane.add(BorderLayout.CENTER,new JPasswordField(10));
pane.add(BorderLayout.EAST,new JButton("忘記密碼"));
return pane;
}
private JPanel createCheckBoxPane(){
JPanel pane=new JPanel(new FlowLayout());
JCheckBox jcb1=new JCheckBox("隱身登陸");
JCheckBox jcb2=new JCheckBox("記住密碼");
pane.add(jcb1);
pane.add(jcb2);
return pane;
}
private JPanel createButtonPane(){
JPanel pane=new JPanel(new FlowLayout());
JButton denglu=new JButton("登陸");
JButton quxiao=new JButton("取消");
JComboBox jcbb=new JComboBox();
String[]jc={"上線","隱身","離線","忙碌"};
jcbb=new JComboBox(jc);
pane.add(denglu);
pane.add(quxiao);
pane.add(jcbb);
return pane;
}
public void ActionListener(){
for(int i=0;i<=i;i++)
System.out.println(i);
}
public void xianshi(){
setVisible(true);
}
}
下面是主函數的代碼 估計包可能還有問題 還有圖片的問題
package com.demo4;
public class Main1 {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Demo1 a=new Demo1();
a.xianshi();
}
}
3. 怎樣用JAVA編寫QQ登陸消息框
lei說的對。
我來詳細來說明一下：源
JButton button = new JButton("OK");
button.addActionListener(this);//這個界面實現一個ActionListener
public void actionPerformed(ActionEvent e){
String cmd = e.getActionCommand();
if("OK".equals(cmd)){
validate();
}
}
private JTextField tfName;//這些控制項都假設你自己add到界面里了
private JPasswordField tpPsw;
public void validate(){
String name = tfName.getText();
char[] psw = tpPsw.getPassword();
if("".equals(name)){System.out.println("填寫名字");return;}
if(psw.length<=0){return;}
//下面自己查詢結果，然後比較密碼。可能需要用到一些加密演算法
}
4. 用java怎麼實現QQ登錄界面
用java做QQ登錄界面的寫法如下：
package ch10;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
1、//定義該類繼承自，實現ActionListener介面
public class LoginTest extends JFrame implements ActionListener
{
2、//創建JPanel對象
private JPanel jp=new JPanel();
3、//創建3個標並加入數組
JLabel name = new JLabel("請輸入用戶名");
JLabel password = new JLabel("請輸入密碼");
JLabel show = new JLabel("");
private JLabel[] jl={name,password,show};
4、//創建登陸和重置按扭並加入數組
JButton login = new JButton("登陸");
JButton reset = new JButton("重置");
private JButton[] jb={login,reset};
5、//創建文本框以及密碼框
private JTextField jName=new JTextField();
private JPasswordField jPassword =new JPasswordField();
public LoginTest()
{
6、//設置布局管理器為空布局，這里自己擺放按鈕、標簽和文本框
jp.setLayout(null);
for(int i=0;i<2;i++)
{
7、//設置標簽和按扭的位置與大小
jl[i].setBounds(30,20+40*i,180,20);
jb[i].setBounds(30+110*i,100,80,20);
8、//添加標簽和按扭到JPanel容器中
jp.add(jl[i]);
jp.add(jb[i]);
//為2個按鈕注冊動作事件監聽器
jb[i].addActionListener(this);
}
9、//設置文本框的位置和大小，注意滿足美觀並足夠用戶名的長度
jName.setBounds(130,15,100,20);
10、//添加文本框到JPanel容器中
jp.add(jName);
11、//為文本框注冊動作事件監聽器
jName.addActionListener(this);
12、//設置密碼框的位置和大小，注意滿足美觀和足夠密碼的長度
jPassword.setBounds(130,60,100,20);
13、//添加密碼框到JPanel容器中
jp.add(jPassword);
14、//設置密碼框中的回顯字元，這里設置美元符號
jPassword.setEchoChar('$');
15、//為密碼框注冊動作事件監聽器
jPassword.addActionListener(this);
16、//設置用於顯示登陸狀態的標簽大小位置，並將其添加進JPanel容器
jl[2].setBounds(10,180,270,20);
jp.add(jl[2]);
17、//添加JPanel容器到窗體中
this.add(jp);
18、//設置窗體的標題、位置、大小、可見性及關閉動作
this.setTitle("登陸窗口");
this.setBounds(200,200,270,250);
this.setVisible(true);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
19、//實現動作監聽器介面中的方法actionPerformed
public void actionPerformed(ActionEvent e)
{
20、//如果事件源為文本框
if(e.getSource()==jName)
{
21、//切換輸入焦點到密碼框
jPassword.requestFocus();
}
22、//如果事件源為重置按扭
else if(e.getSource()==jb[1])
{
23、//清空姓名文本框、密碼框和show標簽中的所有信息
jl[2].setText("");
jName.setText("");
jPassword.setText("");
24、//讓輸入焦點回到文本框
jName.requestFocus();
}
25、//如果事件源為登陸按鈕，則判斷登錄名和密碼是否正確
else
{
26、//判斷用戶名和密碼是否匹配
if(jName.getText().equals("lixiangguo")&&
String.valueOf(jPassword.getPassword()).equals("19801001"))
{
27、jl[2].setText("登陸成功，歡迎您的到來！");
}
else
{
28、jl[2].setText("對不起，您的用戶名或密碼錯誤！");
}
}
}
public static void main(String[] args)
{
29、//創建LoginTest窗體對象
new LoginTest();
}
}
5. qq 第三方登錄 java sdk怎麼用
導入相關的jar包到你的項目里，剩下就是自己看api文檔，結合自己的項目使用。
6. 如何利用java、access製作一個QQ界面並實現登錄功能。。。
...........登錄功能本身，只要通過jdbc執行sql語句，進行查詢操作即可，至於前睜激QQ界面，最簡易的做法是，打開QQ客戶端做個截圖，然後通過jsp引用這個截圖，在用戶早旅名和密碼輸入框那裡，放上輸入域，在登錄那裡，放慧襪上submit按鈕即可，將這兩個元素用form括起來即可。

自己寫的 呵呵不好意思 主要功能就是登陸 和注冊
注冊有用戶名同名時會提示（報錯）
你運行下 就可以了
