Question

我通过smtp发送电子邮件，但只收到文件或附件，而不是电子邮件和主题的正文。谁能告诉我问题出在哪里？

public class SendMail扩展了AppCompatActivity {

EditText edt_subject,edt_body,edt_choosenFile;
private Button sendEmail;
private Button chooseFileButton;
private String filename;
String uniqueId,subject,mailbody;
private static final int REQUEST_CHOOSER = 1234;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_send_mail);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    edt_subject=(EditText)findViewById(R.id.et_Subject);
    edt_body=(EditText)findViewById(R.id.et_mail_body);
    subject=edt_subject.getText().toString();
    mailbody=edt_body.getText().toString();

    sendEmail = (Button) findViewById(R.id.send_email_button_id);
    sendEmail.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new Thread(new Runnable() {

                @Override
                public void run() {
                    try {
                        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 Authenticator() {
                                    protected PasswordAuthentication getPasswordAuthentication() {
                                        return new PasswordAuthentication(
                                                "sender@gmail.com","password");
                                    }
                                });
                        // TODO Auto-generated method stub
                        MimeMessage message = new MimeMessage(session);
                        message.setFrom(new InternetAddress("sender@gmail.com"));
                        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("receiver@gmail.com"));
                        message.setSubject(subject);
                     message.setText(mailbody);

                        if (filename!=null) {

                            BodyPart messageBodyPart = new MimeBodyPart();
                            messageBodyPart.setText(mailbody);
                            Multipart _multipart = new MimeMultipart();
                            FileDataSource source = new FileDataSource(filename);
                            messageBodyPart.setDataHandler(new DataHandler(source));
                            messageBodyPart.setFileName(filename);


                            _multipart.addBodyPart(messageBodyPart);
                            message.setContent(_multipart);
                        }

                        Transport.send(message);
                        System.out.println("Done");
                    } catch (MessagingException e) {
                        throw new RuntimeException(e);
                    }
                }
            }).start();
        }
    });

    chooseFileButton = (Button) findViewById(R.id.choose_file_button_id);
    chooseFileButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Create the ACTION_GET_CONTENT Intent
            Intent getContentIntent = FileUtils.createGetContentIntent();

            Intent intent = Intent.createChooser(getContentIntent, "Select a file");
            startActivityForResult(intent, REQUEST_CHOOSER);
        }
    });
}

主体部分需要是多部分的第一个身体部位。您对message.setTetent的调用将被您对message.setContent的调用覆盖。 JavaMail sample programs中有很多例子。

收到的电子邮件没有正文和邮件主题
