我正在发送带有附件的电子邮件！没关系，但有一个问题。我添加到电子邮件正文的文件具有“完整路径”的名称。发送喜欢...

        class SendEmailAsyncTask extends AsyncTask <Void, Void, Boolean> {
    @Override
    protected Boolean doInBackground(Void... params) {
        {
            Context context = getApplicationContext();
            Mail m = new Mail("****a@gmail.com", "te****mail"); 
            String[] toArr = {"te****all@yan****"}; 
            m.setTo(toArr); 
            m.setFrom("t****il.ya@gmail.com"); 
            m.setSubject("TESTING");         
            m.setBody("Принят test");
            try { 
                String path = "/mnt/sdcard/qwe";
                 File fileDir = new File( path );
                 String[] _files = fileDir.list(); 
                 for ( int i = 0 ; i < _files.length ; i++  )
                 { 
                     _files[i] = path + "/"+ _files[i];
               //        _files[i] = path + "/"+ _files[i].substring(_files[i].lastIndexOf("/"));
                       m.addAttachment(_files[i]);
                       Log.v("list sending", _files[i]);
                       Log.v("list sending", _files[i].substring(_files[i].lastIndexOf("/")));
                 }

              if(m.send()) { 

                  for ( int i = 0 ; i < _files.length ; i++  )
                  { 
                      Log.v("test mail result", "success");
                  }
              } else { 
                  Log.v("test mail result", "fail");
              } 
            } catch(Exception e) {
                 Log.v("test mail result", "error while sending");
            }           
        }
        return null;
    }
}

如何仅获取附件中的文件名？

这是我的 addAttachment 的样子：

public static void addAttachment(String filename) throws Exception { 
    BodyPart messageBodyPart = new MimeBodyPart(); 
    DataSource source = new FileDataSource(filename);        
    messageBodyPart.setDataHandler(new DataHandler(source));

    // Truncating the full file path to just filename
    Pattern p = Pattern.compile("[^/]*$");
    Matcher m = p.matcher(filename);
    if (m.find())
        messageBodyPart.setFileName(m.group());
    else 
        messageBodyPart.setFileName(filename);

    multipart.addBodyPart(messageBodyPart);
  }

希望这可以帮助！

我不知道“邮件”类是什么，但看起来该错误在 Mail.addAttachment 方法中。

试试这个：

messageBodyPart.setFileName(filename.substring(filename.lastIndexOf("/") + 1));
