Java（Android Studio）電子郵件程序

Question

我目前正在android studio中研究AI，並且在發送電子郵件方面遇到了一些問題。 基本上，我點擊了“發送”按鈕，但絕對沒有任何反應。 我仔細檢查了獲取電子郵件密碼/地址/地址的代碼以及所有ID的匹配，並使用了正確的方法。 該方法還匹配正確的按鈕ID。 但是，據我所知，它不會輸出任何錯誤，也不會發送電子郵件。 謝謝你的幫助。

 public void SendEmail(View view) {


        final EditText username = (EditText) findViewById(R.id.IgnisEmailUser);
   final String User = username.getText().toString();
        final EditText password = (EditText) findViewById(R.id.IgnisEmailPass);
    final String Pass = password.getText().toString();
    final EditText toEmail = (EditText) findViewById(R.id.IgnisTheirEmail);
    final String ToEmail = toEmail.getText().toString();
    final EditText body = (EditText) findViewById(R.id.IgnisEmailBody);
    final String Body = body.getText().toString();

    Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");

        Session session = Session.getInstance(props,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(User, Pass);
                    }
                });

        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(User));
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(ToEmail));
            message.setSubject("Sent from Ignis AI");
            message.setText(Body);

            Transport.send(message);

            System.out.println("Done");

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
}

根據要求布局XML：

它不會根據按鈕的ID進行評估，而是根據onClick屬性進行評估。 該按鈕應為and，並且您可以根據需要選擇任何ID。

<Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Send"
        android:id="@+id/SendEmail"
        android:onClick="SendEmail"
        android:layout_alignParentBottom="true"
        android:layout_alignRight="@+id/IgnisEmailBody"
        android:layout_alignEnd="@+id/IgnisEmailBody" />
