在左下角/右下角创建两个按钮

JButton button1 = new JButton("Button 1"); JButton button2 = new JButton("Button 2"); JFrame frame = new JFrame(); frame.getContentPane().setLayout(new BorderLayout()); button2.setLayout(new FlowLayout(FlowLayout.RIGHT)); button1.setLayout(new FlowLayout(FlowLayout.LEFT)); frame.getContentPane().add(button1,BorderLayout.SOUTH); frame.getContentPane().add(button2,BorderLayout.SOUTH); frame.setSize(500,500); frame.setVisible(true); 

我正在尝试在左下角制作按钮1，在右下角制作按钮2

你可能想考虑使用BoxLayout的horizontalGlue ：

 import java.awt.BorderLayout; import javax.swing.Box; import javax.swing.BoxLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.SwingUtilities; public class ButtonsLeftAndRight { private JFrame frame; private JPanel pane; private JButton button1; private JButton button2; public static void main(String[] args) { SwingUtilities.invokeLater(new ButtonsLeftAndRight()::createAndShowGui); } public void createAndShowGui() { frame = new JFrame(getClass().getSimpleName()); pane = new JPanel(); pane.setLayout(new BoxLayout(pane, BoxLayout.LINE_AXIS)); button1 = new JButton("Button1"); button2 = new JButton("Button2"); pane.add(button1); pane.add(Box.createHorizontalGlue()); pane.add(button2); frame.add(pane, BorderLayout.SOUTH); frame.pack(); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } } 

这可能会在resize之前和之后得到这个：

为两者创建容器。

 JPanel south = new JPanel(new AxisLayout(AxisLayout.HORIZONTAL)); south.add(button1); south.add(button2); frame.getContentPane().add(south, BorderLayout.SOUTH); 

Obs：对不起，不记得Swing布局管理员，但你会发现AxisLayout来解决这个问题

另一种方法是使用GUI构建器，并相应地修改代码。

 JButton button1 = new JButton("Button 1"); JButton button2 = new JButton("Button 2"); JFrame frame = new JFrame(); GroupLayout layout = new GroupLayout(frame.getContentPane()); frame.getContentPane().setLayout(layout); layout.setHorizontalGroup( layout.createParallelGroup(GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addGap(25, 25, 25) .addComponent(button1) .addPreferredGap(LayoutStyle.ComponentPlacement.RELATED, 215, Short.MAX_VALUE) .addComponent(button2) .addContainerGap()) ); layout.setVerticalGroup( layout.createParallelGroup(GroupLayout.Alignment.LEADING) .addGroup(javax.swing.GroupLayout.Alignment.TRAILING, layout.createSequentialGroup() .addContainerGap(256, Short.MAX_VALUE) .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE) .addComponent(button1) .addComponent(button2)) .addGap(25, 25, 25)) ); frame.setSize(500, 500); frame.setVisible(true);

您可以添加一个jPanel ，然后将两个按钮添加到它，然后在按钮上调用setBounds并指定位置。 然后将jPanel添加到jFrame 。

 JButton button1 = new JButton("Button 1"); JButton button2 = new JButton("Button 2"); JFrame frame = new JFrame(); JPanel p = new JPanel(); p.setLayout(null); button1.setBounds(10, 400, 100, 40); p.add(button1); button2.setBounds(375, 400, 100, 40); p.add(button2); frame.getContentPane().add(p); frame.setSize(500, 500); frame.setVisible(true); 

边界设置为（x-coord，y-coord，width，height）。
