如何获取JList中的项目并将其删除？

Question

我无法从JList中删除一个项目。以下代码已放在JButton上。

DefaultListModel model = (DefaultListModel) list1.getModel(); 

    int selectedIndex = list1.getSelectedIndex(); 
    if (selectedIndex != -1) 
    { 
    model.remove(selectedIndex); 
    } 

Answer 1

下面的代码应该工作

JButton removeButton = new JButton("Remove Selected Element"); 
removeButton.addActionListener(new ActionListener() { 
    public void actionPerformed(ActionEvent event) { 
     int selectedIndex = list1.getSelectedIndex(); 
     if (selectedIndex != -1) { 
      model.remove(selectedIndex); 
     } else { 
      System.out.println("Nothing selected"); 
     } 
    } 
});
