我需要一个基本的简单Java布局方法
我已经在互联网上检查了FlowLayout，Group等等，所有这些都是无用的例子。我只需要一个基本的方法来为我的Java应用程序做一个好的布局。我会告诉你我的代码：
import java.awt.*;
import javax.swing.*;
import javax.swing.border.Border;
import javax.swing.border.LineBorder;
public class Test1 {
//Step1 - Declaring variables
private static JFrame myFrame;
private static JPanel myPanel;
private static JLabel titleLabel=null;
private static JLabel logIn=null;
private static JLabel username=null;
private static JLabel password=null;
private static JTextField usernameField=null;
private static JPasswordField passwordField=null;
private static Color myColor=new Color(0, 102, 204);
private static Font myFont11=new Font("Tahoma", 1, 11);
private static Font myFont12bold=new Font("Tahoma", Font.BOLD, 12);
private static Font myFont11bold=new Font("Tahoma", Font.BOLD, 11);
//Step2 - Creating Components
public void createComponents() {
//Title Label
titleLabel=new JLabel("My Program");
titleLabel.setForeground(Color.white);
titleLabel.setFont(myFont12bold);
//titleLabel.setVisible(false); //hide it or show it
//--------------------------------------------------------
logIn=new JLabel("Log in");
logIn.setFont(myFont11bold);
logIn.setForeground(Color.white);
username=new JLabel("Username");
username.setLabelFor(usernameField);
username.setFont(myFont11);
username.setForeground(Color.white);
password=new JLabel("Password");
password.setLabelFor(passwordField);
password.setFont(myFont11);
password.setForeground(Color.white);
usernameField=new JTextField(10);
usernameField.setBorder(new LineBorder(null, 0, false));
passwordField=new JPasswordField(10);
passwordField.setBorder(new LineBorder(null, 0, false));
//Panel
myPanel=new JPanel();
myPanel.setBackground(myColor);
myPanel.add(titleLabel);
myPanel.add(logIn);
myPanel.add(mySeparator2);
myPanel.add(username);
myPanel.add(usernameField);
myPanel.add(password);
myPanel.add(passwordField);
//----------------------------------------------------------
//Step3 - Main Function
public static void main(String[] arg) {
//Frame
myFrame=new JFrame();
myFrame.setPreferredSize(new Dimension(400,300));//width:400px, height:300px
myFrame.setLocationRelativeTo(null);//to show at center of screen
myFrame.setTitle("My Program");
Test1 prog=new Test1();
prog.createComponents();
myFrame.add(myPanel);
myFrame.pack();//this alone will not give the frame a size
myFrame.setVisible(true);
//----------------------------------------------------------------------
}
}
这是一个基本的gui，它有一些标签和一些文本字段，.pack（）方法它们将显示在同一行上，我只需要一个简单的小方法来制作一个好的布局

答案 0 :(得分：4)
由于许多原因，代码中的static个变量太多不是理想的解决方案。尝试使用不同的方法，除非您不考虑为Factory Class制作一个Project。看看这个修改过的版本，这还不错：
import java.awt.*;
import javax.swing.*;
import javax.swing.border.Border;
import javax.swing.border.LineBorder;
public class Test1 {
//Step1 - Declaring variables
private JFrame myFrame;
// Added by me
private JPanel contentPane;
private JPanel myPanel;
private JLabel username=null;
private JLabel password=null;
private JTextField usernameField=null;
private JPasswordField passwordField=null;
private Color myColor=new Color(200, 102, 204);
private Font myFont11=new Font("Tahoma", 1, 11);
private Font myFont12bold=new Font("Tahoma", Font.BOLD, 12);
private Font myFont11bold=new Font("Tahoma", Font.BOLD, 11);
//Step2 - Creating Components
public void createComponents() {
contentPane = new JPanel();
contentPane.setOpaque(true);
contentPane.setBackground(Color.WHITE);
contentPane.setLayout(new GridBagLayout());
contentPane.setBorder(BorderFactory.createTitledBorder("My Program"));
username=new JLabel("Username");
username.setLabelFor(usernameField);
username.setFont(myFont11);
username.setForeground(Color.white);
password=new JLabel("Password");
password.setLabelFor(passwordField);
password.setFont(myFont11);
password.setForeground(Color.white);
usernameField=new JTextField(10);
usernameField.setBorder(new LineBorder(null, 0, false));
passwordField=new JPasswordField(10);
passwordField.setBorder(new LineBorder(null, 0, false));
//Panel
myPanel=new JPanel();
myPanel.setOpaque(true);
myPanel.setBorder(BorderFactory.createTitledBorder("Login"));
myPanel.setBackground(myColor);
myPanel.setLayout(new GridLayout(2, 2, 2, 2));
myPanel.add(username);
myPanel.add(usernameField);
myPanel.add(password);
myPanel.add(passwordField);
//----------------------------------------------------------
contentPane.add(myPanel);
myFrame=new JFrame();
myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//myFrame.setPreferredSize(new Dimension(400,300));//width:400px, height:300px
myFrame.setLocationRelativeTo(null);//to show at center of screen
myFrame.setTitle("My Program");
//myFrame.add(myPanel);
myFrame.setContentPane(contentPane);
myFrame.pack();//this alone will not give the frame a size
myFrame.setVisible(true);
}
//Step3 - Main Function
public static void main(String[] arg) {
SwingUtilities.invokeLater(new Runnable()
{
public void run()
{
new Test1().createComponents();
}
});
}
}
这是输出：
答案 1 :(得分：3)
1）你有关于debuging，java约定和包装方法和类的问题，你有问题和
2）添加一个新的大括号
}//add this one
public static void main(String[] arg) {
}
}
3）在Initail Thread中构建了Swing GUI，然后你的主类应该是
public static void main(String[] arg) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
myFrame = new JFrame();
myFrame.setPreferredSize(new Dimension(400, 300));//width:400px, height:300px
myFrame.setLocationRelativeTo(null);//to show at center of screen
myFrame.setTitle("My Program");
Test1 prog = new Test1();
prog.createComponents();
myFrame.add(myPanel);
myFrame.pack();//this alone will not give the frame a size
myFrame.setVisible(true);
}
});
}
4）setSize JFrame然后pack();的使用是反效果使用pack()而不是setSize
5）如果您要将更多相似的JComponents放在那里，您可以查看SpringLayout或GridBagLayout，
答案 2 :(得分：2)
对于那些类型的UI（标签 - 编辑器组件），我发现FormLayout {{1}}是最好的，并且非常容易使用。

看起来你正在登录表格...
您可以使用两行和一列的网格布局在一行上它将包含标签，文本字段，如果您不想将事件处理程序提供给最后一个文本字段，则第二个也与附加一个按钮相同
这是我设计的一个简单登录表单的代码，不使用任何拖放工具
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class LoginFrame extends JFrame{
User user;
private JPanel buttonPanel;
JButton btnLogin;
JButton btnRegister;
JButton btnExit;
JPanel panelUser;
JPanel panelPwd;
JLabel nameLabel;
final JTextField txtUserName;
final JPasswordField txtPwd;
public LoginFrame() {
user = new User();
setTitle("Demo for next Button frame");
setSize(370, 169);
JPanel masterPanel = new JPanel();
buttonPanel = new JPanel();
btnLogin = new JButton("Log in");
btnExit = new JButton("Exit");
btnRegister = new JButton("Register");
buttonPanel.add(btnLogin);
buttonPanel.add(btnExit);
buttonPanel.add(btnRegister);
panelUser = new JPanel();
panelPwd = new JPanel();
nameLabel = new JLabel("user name");
txtUserName = new JTextField("", 20);
JLabel pwdLabel = new JLabel("password");
txtPwd = new JPasswordField("", 20);
panelUser.add(nameLabel);
panelUser.add(txtUserName);
panelPwd.add(pwdLabel);
panelPwd.add(txtPwd);
masterPanel.add(panelUser);
masterPanel.add(panelPwd);
masterPanel.add(buttonPanel);
add(masterPanel, BorderLayout.CENTER);
btnRegister.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
user.setUserName(JOptionPane.showInputDialog(null,"Enter user name you want"));
user.setPassword(JOptionPane.showInputDialog(null,"Enter password you want"));
JOptionPane.showMessageDialog(null, "now log in with your user name and password");
user.saveFile();
}
});
btnLogin.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent event){
if(txtUserName.getText().equals(user.getUserName()) && (new String(txtPwd.getPassword())).equals(user.getPassword())){
dispose();
user.saveLog();
TimeFrame tFrame = new TimeFrame(user.getUserName());
tFrame.setVisible(true);
tFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
// Determine the new location of the window
int w = tFrame.getSize().width;
int h = tFrame.getSize().height;
int x = (dim.width-w)/2;
int y = (dim.height-h)/2;
// Move the window
tFrame.setLocation(x, y);
} else {
JOptionPane.showMessageDialog(null,"User name or password don't match","Acces Denied", JOptionPane.ERROR_MESSAGE);
}
}
});
btnExit.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent event){
dispose();
}
});
}
}
你可以看到代码......
有基本布局作为流程布局摆动应用程序和gridlayout的默认布局 在流布局中，添加到框架中的组件从右向左流动，每次更改框架的大小时，它们的方向都会发生变化，因此趋向于流动，因此称为流程布局
在网格布局中，组件对齐到n x m维的网格中
n：行数和n：它类似于网格的列数因此，如果你调整窗口大小，名称就不会在网格布局中发生，因为它是为同一目的而设计的......
fyi：标有网格2x2的框架是网格布局的输出，其他框架是o / p的流程布局请研究按钮排列的不同，改变窗口的大小

你不使用IDE吗？ JDeveloper和Netbeans是具有拖放功能的出色解决方案

您可以使用windowBuilder eclipse插件，它有助于以您想要的方式形成布局。 例如，我使用windowbuilder创建了一个简单的布局，以这种方式形成代码
