java實現簡單QQ登陸界面：
1.生成界面的java代碼
packageQQ2014;
importjavax.swing.*;
importjava.awt.*;
importjava.awt.event.*;
publicclassQQ2014{
//創建登陸界面類
publicvoidshowLoginFrame(){
//創建船體對象
JFrameloginFrame=newJFrame();
//設置大小，位置，標題
loginFrame.setSize(300,200);
loginFrame.setTitle("QQ2014");
loginFrame.setLocationRelativeTo(null);
//創建流式分布對象
FlowLayoutlayout=newFlowLayout();
loginFrame.setLayout(layout);
//創建賬戶名，密碼和輸入框
JLabeluser_name=newJLabel("賬號：");
JLabeluser_password=newJLabel("密碼：");
JTextFieldfield_name=newJTextField(20);
JPasswordFieldfield_password=newJPasswordField(20);
//創建登陸，重置按鈕
JButtonbutton_reset=newJButton("重置");
JButtonbutton_login=newJButton("登陸");
//設置窗體可見
loginFrame.setVisible(true);
//創建事件監聽對象
ActionListeneraction_listener1=newActionListener(){
publicvoidactionPerformed(ActionEvente){
Stringname=field_name.getText();
Stringpassword=field_password.getText();
if("zhaoxin".equals(name)&&"123".equals(password))
{
showIndexFrame();
loginFrame.setDefaultCloseOperation(3);
loginFrame.setVisible(false);
}
else{
System.out.println("密碼錯誤，重新輸入!");
}
}
};
ActionListeneraction_listener2=newActionListener(){
publicvoidactionPerformed(ActionEvente){
field_name.setText("");
field_password.setText("");
}
};
//將文本輸入框，按鈕，事件監聽對象添加
loginFrame.add(user_name);
loginFrame.add(field_name);
loginFrame.add(user_password);
loginFrame.add(field_password);
loginFrame.add(button_reset);
loginFrame.add(button_login);
button_reset.addActionListener(action_listener2);
button_login.addActionListener(action_listener1);
}
publicvoidshowIndexFrame(){
//創建窗體對象
JFrameindexFrame=newJFrame();
indexFrame.setSize(200,500);
indexFrame.setTitle("QQ好友列表");
indexFrame.setLocationRelativeTo(null);
//設置流式分布對象
FlowLayoutlayout=newFlowLayout(FlowLayout.CENTER,100,10);
indexFrame.setLayout(layout);
//創建好友按鈕
for(inti=0;i<10;i++)
{
JButtonbutton_friend=newJButton("friend"+i);
//創建動作事件監聽對象
ActionListeneraction_listener=newActionListener()
{
publicvoidactionPerformed(ActionEvente)
{
showChatFrame();
indexFrame.setVisible(false);
indexFrame.setDefaultCloseOperation(3);
}
};
button_friend.addActionListener(action_listener);
indexFrame.add(button_friend);
}
//設置窗體可見
indexFrame.setVisible(true);
}
publicvoidshowChatFrame(){
//創建窗體，大小，位置，標題
JFramechatFrame=newJFrame();
chatFrame.setSize(400,400);
chatFrame.setTitle("正在聊天中...");
chatFrame.setLocationRelativeTo(null);
//創建聊天記錄，輸入域
JTextAreaarea_input=newJTextArea(10,30);
JTextAreaarea_record=newJTextArea(5,30);
//創建流式分布對象
FlowLayoutlayout=newFlowLayout(FlowLayout.CENTER,0,10);
chatFrame.setLayout(layout);
//創建發送，關閉按扭
JButtonbutton_send=newJButton("發送");
JButtonbutton_close=newJButton("關閉");
//創建動作事件監聽對象
ActionListeneraction_listener1=newActionListener()
{
publicvoidactionPerformed(ActionEvente){
area_record.setText(area_record.getText()+" "+area_input.getText());
area_input.setText("");
}
};
ActionListeneraction_listener2=newActionListener()
{
publicvoidactionPerformed(ActionEvente){
chatFrame.setVisible(false);
chatFrame.setDefaultCloseOperation(3);
}
};
//設置窗體可見
chatFrame.setVisible(true);
//添加按鈕，事件監聽對象
chatFrame.add(area_record);
chatFrame.add(area_input);
chatFrame.add(button_send);
chatFrame.add(button_close);
button_send.addActionListener(action_listener1);
button_close.addActionListener(action_listener2);
}
}
復制代碼
2.javamain方法調用
packageQQ2014;
publicclassTest{
publicstaticvoidmain(String[]args){
QQ2014qq=newQQ2014();
qq.showLoginFrame();
}
}

2. 用java製作qq登錄界面,只要界面,不要事件處理
package ibees.qq;
import java.awt.BorderLayout;
import java.net.URL;
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;
/**
* 仿QQ登錄界面，僅供學習參考，涉及到的有窗口居中、JPanel、LayoutManager的使用
* @author hhzxj2008
* */
public class QQLoginView extends JFrame {
/**
*
*/
private static final long serialVersionUID = -5665975170821790753L;
public QQLoginView() {
initComponent();
}
private void initComponent() {
setTitle("用戶登錄");
//設置LOGO
URL image = QQLoginView.class.getClassLoader().getResource("ibees/qq/images/year.jpg");//圖片的位置
JLabel imageLogo = new JLabel(new ImageIcon(image));
add(imageLogo,BorderLayout.NORTH);
//QQ號和密碼
JPanel jp = new JPanel();
JPanel jpAccount = new JPanel();
jpAccount.add(new JLabel("帳號"));
JTextField userTextField = new JTextField(15);
jpAccount.add(userTextField);
jpAccount.add(new JLabel("用戶注冊"));
jp.add(jpAccount);
JPanel jpPass = new JPanel();
jpPass.add(new JLabel("密碼"));
JPasswordField passTextField = new JPasswordField(15);
jpPass.add(passTextField);
jpPass.add(new JLabel("找回密碼"));
jp.add(jpPass);
//登錄設置
JPanel jpstatus = new JPanel();
jpstatus.add(new JLabel("狀態"));
JComboBox statusComboBox = new JComboBox();
statusComboBox.addItem("Q我");
statusComboBox.addItem("在線");
statusComboBox.addItem("隱身");
statusComboBox.addItem("離線");
jpstatus.add(statusComboBox);
jpstatus.add(new JCheckBox("記住密碼"));
jpstatus.add(new JCheckBox("自動登錄"));
jp.add(jpstatus);
add(jp);
//底部登錄按鈕
JPanel bottomPanel = new JPanel();
bottomPanel.setLayout(new BorderLayout());
bottomPanel.add(new JButton("設置"),BorderLayout.WEST);
bottomPanel.add(new JButton("登錄"),BorderLayout.EAST);
add(bottomPanel,BorderLayout.SOUTH);
setSize(324,230);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setLocationRelativeTo(null);
}
/**
* @param args
*/
public static void main(String[] args) {
java.awt.EventQueue.invokeLater(new Runnable(){
@Override
public void run() {
new QQLoginView().setVisible(true);
}
});
}
}
3. 登錄界面，用Java做，類似於QQ的，要求有用戶名，密碼，以及登錄按鈕，當登陸成功時，提示登陸成功！

4. 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(){

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(){

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(){

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();
}
}
5. 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();
}
}
6. 怎麼用JAVA編寫QQ的登陸界面
if(輸入的用戶名和密碼正確此困枝)
{
JOptionPane.showMessageDialog(JFrame,"登陸狀態","恭喜你登陸成功",JOptionPane.YES_OPTION,JOptionPane.INFORMATION_MESSAGE);
}
else if(輸入的用戶名和密碼不正確)
{
JOptionPane.showMessageDialog(JFrame,"登陸尺好狀態","對不起森敏登陸失敗",JOptionPane.YES_OPTION,JOptionPane.ERROR_MESSAGE);
}
7. 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。
8. 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JFrame，實現ActionListener介面

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橘殲與大小
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
