您可以创建一个自定义
ListSelectionModel。
简单的例子：
import java.awt.*;import java.awt.event.*;import javax.swing.*;public class ToggleListSelectionModel extends DefaultListSelectionModel{ @Override public void setSelectionInterval(int index0, int index1) { // Select multiple lines if (index0 != index1) { super.addSelectionInterval(index0, index1); return; } // Toggle selection of a single line if (super.isSelectedIndex(index0)) { super.removeSelectionInterval(index0, index0); } else { super.addSelectionInterval(index0, index0); } } private static void createAndShowGUI() { String[] numbers = { "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten" }; final JList<String> list = new JList<String>( numbers ); list.setVisibleRowCount( numbers.length ); list.setSelectionModel(new ToggleListSelectionModel());// list.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION); JButton clear = new JButton("Clear"); clear.addActionListener( new ActionListener() { public void actionPerformed(ActionEvent e) { list.clearSelection(); } }); Jframe frame = new Jframe("SSCCE"); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); frame.add(new JScrollPane(list), BorderLayout.CENTER); frame.add(clear, BorderLayout.PAGE_END); frame.setLocationByPlatform( true ); frame.pack(); frame.setVisible( true ); } public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); }}该示例适用于JList，但是JTable也使用ListSelectionModel。
