我做了在XML文件中的用戶界面和我能

驗證註冊登記的所有字段Email_Navigator.Java文件，但同時按鈕調

點擊提交超過郵件應該去輸入電子郵件。我怎樣才能做到這一點？

Answer 1

創建類

1. Session.java

   private Session createSessionObject() { 
       Properties properties = new Properties(); 
       properties.put("mail.smtp.auth", "true"); 
       properties.put("mail.smtp.starttls.enable", "true"); 
       properties.put("mail.smtp.host", "smtp.gmail.com"); 
       properties.put("mail.smtp.port", "587"); 
   
       return Session.getInstance(properties, new javax.mail.Authenticator() { 
       protected PasswordAuthentication getPasswordAuthentication() { 
        return new PasswordAuthentication(username, password); 
       } 
       }); 
   } 
   

2. Message.java

   private Message createMessage(String email, String subject, String messageBody, Session session) throws MessagingException, UnsupportedEncodingException { 
       Message message = new MimeMessage(session); 
       message.setFrom(new InternetAddress("tutorials@tiemenschut.com", "Tiemen Schut")); 
       message.addRecipient(Message.RecipientType.TO, new InternetAddress(email, email)); 
       message.setSubject(subject); 
       message.setText(messageBody); 
       return message; 
   } 
   

定義在活動發送這樣的郵件的內部類：

private class SendMailTask extends AsyncTask<Message, Void, Void> { 
private ProgressDialog progressDialog; 

@Override 
protected void onPreExecute() { 
    super.onPreExecute(); 
    progressDialog = ProgressDialog.show(MainActivity.this, "Please wait", "Sending mail", true, false); 
} 

@Override 
protected void onPostExecute(Void aVoid) { 
    super.onPostExecute(aVoid); 
    progressDialog.dismiss(); 
} 

@Override 
protected Void doInBackground(Message... messages) { 
    try { 
     Transport.send(messages[0]); 
    } catch (MessagingException e) { 
     e.printStackTrace(); 
    } 
    return null; 
} 
} 

然後在最後調用此方法在您的onClick：

private void sendMail(String email, String subject, String messageBody) { 
    Session session = createSessionObject(); 

    try { 
     Message message = createMessage(email, subject, messageBody, session); 
     new SendMailTask().execute(message); 
    } catch (AddressException e) { 
     e.printStackTrace(); 
    } catch (MessagingException e) { 
     e.printStackTrace(); 
    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } 
} 

注：用戶名密碼&在passswordAuthentication（）是你將要使用的發送郵件的郵件憑證。
