Question

我一直试图点击“帮助”按钮打开htmlfile。我需要将文件导入源包，因此在构建后它不会显示错误。我正在使用netbeans。当我将文件复制到src并尝试运行该文件时，它在编译时显示错误。我想知道如何将文件添加到src以及如何通过向用户询问系统中安装的浏览器列表来打开。这是我搜索过并试过的代码。谢谢提前

  try 
  {           
      File htmlFile = new File(this.getClass().getResource("help.html").getFile());
      Desktop.getDesktop().browse(htmlFile.toURI());
  } 
  catch (IOException ex)
  {
      System.out.println(ex);
  }

Answer 1

我尝试使用My Desktop html文件。现在它的工作正常。它对你有用。（我的默认浏览器是chrome）

试试吧。

import java.awt.BorderLayout;
import java.awt.Button;
import java.awt.Desktop;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class FileOpenBrowser {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        JFrame frame = new JFrame("FileOpenBrowser"); // set API Name
        JPanel topPanel = new JPanel(new FlowLayout()); // set Panel Layout

        File urlDesktop = new File(
                "C://Documents and Settings/Hariharan/Desktop/help.html");

        Button btn = new Button("Help");
        btn.setBounds(50, 100, 60, 30);
        topPanel.add(btn);

        frame.add(topPanel, BorderLayout.PAGE_START);

        frame.setSize(300, 300);
        frame.setVisible(true);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        btn.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                try {
                    Desktop.getDesktop().open(urlDesktop);
                } catch (Exception e1) {
                    e1.printStackTrace();
                }
            }
        });
    }
}

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;

public class FileOpenBrowser {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        JFrame frame = new JFrame("FileOpenBrowser"); // set API Name
        JPanel topPanel = new JPanel(new FlowLayout()); // set Panel Layout

        Button btn = new Button("Help");
        btn.setBounds(50, 100, 60, 30);
        topPanel.add(btn);

        frame.add(topPanel, BorderLayout.PAGE_START);

        frame.setSize(300, 300);
        frame.setVisible(true);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        btn.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                try {
                    System.out.println("Start..");
                    File file = new java.io.File("src/help.html").getAbsoluteFile();
                    Desktop.getDesktop().open(file);                    
                    System.out.println("End..");
                } catch (Exception e1) {
                    e1.printStackTrace();
                }
            }
        });
    }
}
