android ftp文件上传进度监听

Question

用的库是 commons-net-3.0.1.jar，现在想获取已上传文件大小以更新进度条，请问各位前辈有没有什么办法？如果方便的话能否简单给几行代码，谢谢！

        public String ftpUpload(String url, String port, String username,String password, String remotePath, String fileNamePath,String fileName) {

        FTPClient ftpClient = new FTPClient();  

        FileInputStream fis = null;  

        String returnMessage = "0";  

        try {  

            ftpClient.connect(url, Integer.parseInt(port));  

            boolean loginResult = ftpClient.login(username, password);  

            int returnCode = ftpClient.getReplyCode();  

            if (loginResult && FTPReply.isPositiveCompletion(returnCode)) {// 如果登录成功  

                ftpClient.makeDirectory(remotePath);  

                 // 设置上传目录  

                ftpClient.changeWorkingDirectory(remotePath);  

                ftpClient.setBufferSize(1024);  

                ftpClient.setControlEncoding("UTF-8");  

                ftpClient.enterLocalPassiveMode();  

                fis = new FileInputStream(fileNamePath + fileName);  

                ftpClient.storeFile(fileName, fis);  

                returnMessage = "1";   //上传成功        

            } else {// 如果登录失败  
                returnMessage = "0";  

            }  

        } catch (IOException e) {  

            e.printStackTrace();  

            throw new RuntimeException("FTP客户端出错！", e);  

        } finally {


         //IOUtils.closeQuietly(fis);  

         try {

             ftpClient.disconnect();  

         } catch (IOException e) {

             e.printStackTrace();  

             throw new RuntimeException("关闭FTP连接发生异常！", e);  
         }  
        }  

     return returnMessage;  

        }  
    }

上传文件以及封装好了，除非你使用原始字节流的方式上传，才能获取上传进度。
或者弄个假进度条，哈哈
