在Java中使用Windows资源管理器的“打开文件”功能

在Java中使用它将打开Windows资源管理器到C盘:

Desktop.getDesktop().open(new File("c:\\"));

但是,我还需要在此处突出显示“打开文件”功能:http://i.imgur.com/XfgnozF.jpg

有没有办法在Java中实现它(使用Windows资源管理器,而不是Swing的FileChooser)?

在使用原生系统的JFileChooser时,请查看使用look & feel

enter image description here

public class NativeOpenDialogDemo {

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                final JFrame frame = new JFrame("Open File Example");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                JButton openButton = new JButton("Open");
                openButton.addActionListener(new ActionListener() {

                    @Override
                    public void actionPerformed(ActionEvent e) {
                        JFileChooser chooser = new JFileChooser();
                        if (chooser.showOpenDialog(frame) == JFileChooser.APPROVE_OPTION) {
                            // do something
                        }
                    }
                });
                frame.add(openButton);
                frame.pack();
                frame.setLocationByPlatform(true);
                frame.setVisible(true);
            }
        });
    }
}

我们可以使用JFileChooser,

JFileChooser chooser = new JFileChooser();
            int status = chooser.showOpenDialog(null);
            if (status == JFileChooser.APPROVE_OPTION) {
                File file = chooser.getSelectedFile();
                if (file == null) {
                    return;
                }

                String fileName = chooser.getSelectedFile().getAbsolutePath();
   ......

            }
