我正在使用已为Android找到的here移植的JavaMail API,但我无法弄清楚如何使用它发送HTML格式的电子邮件。
设置电子邮件的活动:
public class Mail extends javax.mail.Authenticator {
private String _user;
private String _pass;
private String[] _to;
private String _from;
private String _port;
private String _sport;
private String _host;
private String _subject;
private String _body;
private boolean _auth;
private boolean _debuggable;
private Multipart _multipart;
public Mail() {
_host = "smtp.gmail.com"; // default smtp server
_port = "465"; // default smtp port
_sport = "465"; // default socketfactory port
_user = ""; // username
_pass = ""; // password
_from = ""; // email sent from
_subject = ""; // email subject
_body = " "; // email body
_debuggable = false; // debug mode on or off - default off
_auth = true; // smtp authentication - default on
_multipart = new MimeMultipart();
// There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added.
MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
mc.addMailcap("message/rfc822;; x-java-content- handler=com.sun.mail.handlers.message_rfc822");
CommandMap.setDefaultCommandMap(mc);
}
public Mail(String user, String pass) {
this();
_user = user;
_pass = pass;
}
public boolean send() throws Exception {
Properties props = _setProperties();
if(!_user.equals("") && !_pass.equals("") && _to.length > 0 && !_from.equals("") && !_subject.equals("") && !_body.equals("")) {
Session session = Session.getInstance(props, this);
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(_from));
InternetAddress[] addressTo = new InternetAddress[_to.length];
for (int i = 0; i < _to.length; i++) {
addressTo[i] = new InternetAddress(_to[i]);
}
msg.setRecipients(MimeMessage.RecipientType.TO, addressTo);
msg.setSubject(_subject);
msg.setSentDate(new Date());
// setup message body
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(_body, "text/html");
_multipart.addBodyPart(messageBodyPart);
// Put parts in message
msg.setContent(_multipart );
// send email
Transport.send(msg);
return true;
} else {
return false;
}
}
public void addAttachment(String filename) throws Exception {
BodyPart messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
_multipart.addBodyPart(messageBodyPart);
}
@Override
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(_user, _pass);
}
private Properties _setProperties() {
Properties props = new Properties();
props.put("mail.smtp.host", _host);
if(_debuggable) {
props.put("mail.debug", "true");
}
if(_auth) {
props.put("mail.smtp.auth", "true");
}
props.put("mail.smtp.port", _port);
props.put("mail.smtp.socketFactory.port", _sport);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
return props;
}
public void setTo(String[] _to) {
this._to = _to;
}
public void setFrom(String _from) {
this._from = _from;
}
public void setSubject(String _subject) {
this._subject = _subject;
}
public void setBody(Spanned string) {
this._body=string.toString();
}
}
尝试发送电子邮件的活动:
Mail m = new Mail("email address", "password");
String[] toArr = {Email1, Email2};
m.setTo(toArr);
m.setSubject("This is just a test");
String sb=("Android</br>Testing</br><b> test </b>");
m.setBody(Html.fromHtml(sb));
try {
m.addAttachment("/sdcard/+"Image1.PNG");
if(m.send()) {
Toast.makeText(this, "Email was sent successfully.", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Email was not sent.", Toast.LENGTH_LONG).show();
}
} catch(Exception e) {
//Toast.makeText(MailApp.this, "There was a problem sending the email.", Toast.LENGTH_LONG).show();
Log.e("MailApp", "Could not send email", e);
}
}

在你的代码中,而不是使用“text / html”只使用“text / html; charset = ISO-8859-1”。它应该工作。消息的字符串必须已包含html标记。例如......
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent("my message in html <br /> <strong> text in bold </strong>", "text/html; charset=ISO-8859-1");
multipart.addBodyPart(messageBodyPart);

您可以使用GMAILSender类。看看this link
尝试在GmailSender.java中使用text / html
,而不是使用text / plain答案 2 :(得分:0)
对于这个具体的例子,我的做法和rodrigoa的做法一样。如果您遵循this tutorial,请执行以下操作。获得成功的html页面后,您可以根据需要进行更改。
sMail.setFrom("wooo@wooo.com");
sMail.setSubject("This is an email sent using my Mail JavaMail wrapper from an Android device.");
/* Notice the html tags below. You could use StringBuilder to send a Google Map
* of whatever other HTML content you want here. */
sMail.setBody("<HTML><CENTER><H1>IT WORKS</H1><C/ENTER></HTML>");
然后在您的主要活动中,将其更改为以下内容:
// setup message body
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(_body, "text/html; charset=ISO-8859-1");
_multipart.addBodyPart(messageBodyPart);
希望这能节省一些时间。
