Android 实现发邮件，使用JavaMail方式实现

MailSenderInfo 类

package com.example.mailtestdemo;import java.util.Properties;public class MailSenderInfo {// 发送邮件的服务器的IP和端口private String mailServerHost;private String mailServerPort = "25";// 邮件发送者的地址private String fromAddress;// 邮件接收者的地址private String toAddress;// 登陆邮件发送服务器的用户名和密码private String userName;private String password;// 是否需要身份验证private boolean validate = true;// 邮件主题private String subject;// 邮件的文本内容private String content;// 邮件附件的文件名private String[] attachFileNames;  /** * 获得邮件会话属性 */public Properties getProperties(){Properties p = new Properties();p.put("mail.smtp.host", this.mailServerHost);p.put("mail.smtp.port", this.mailServerPort);p.put("mail.smtp.auth", "true");//validate ? "true" : "false"return p;}public String getMailServerHost(){return mailServerHost;}public void setMailServerHost(String mailServerHost){this.mailServerHost = mailServerHost;}public String getMailServerPort(){return mailServerPort;}public void setMailServerPort(String mailServerPort){this.mailServerPort = mailServerPort;}public boolean isValidate(){return validate;}       public void setValidate(boolean validate){this.validate = validate;}public String[] attachFileNames(){return attachFileNames;}public void setAttachFileNames(String[] fileNames){this.attachFileNames = fileNames;}public String getFromAddress(){return fromAddress;}public void setFromAddress(String fromAddress){this.fromAddress = fromAddress;}public String getToAddress(){return toAddress;}public void setToAddress(String toAddress){this.toAddress = toAddress;}        public String getPassword(){return password;}public void setPassword(String password){this.password = password;}public String getUserName(){return userName;}public void setUserName(String userName){this.userName = userName;}public String getSubject(){return subject;}public void setSubject(String subject){this.subject = subject;}public String getContent(){return content;}        public void setContent(String textcontent){this.content = textcontent;}}

MultiMailsender 类

package com.example.mailtestdemo;import java.util.Date;import java.util.Properties;import javax.mail.Address;import javax.mail.BodyPart;import javax.mail.Message;import javax.mail.MessagingException;import javax.mail.Multipart;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeBodyPart;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeMultipart;/** *发送邮件给多个接收者，抄送者  */public class MultiMailsender {/** * 以文本格式发送邮件 */public boolean sendTextMail(MultiMailSenderInfo mailInfo){// 判断是否需要身份认证MyAuthenticator authenticator = null;Properties pro = mailInfo.getProperties();if(mailInfo.isValidate()){// 如果需要身份认证，则创建一个密码验证器authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());}// 根据邮件会话属性和密码验证器构造一个发送邮件的sessionSession sendMailSession = Session.getDefaultInstance(pro, authenticator);

                   try { Message mailMessage = new MimeMessage(sendMailSession); // 创建邮件发送者地址 Address from = new InternetAddress(mailInfo.getFromAddress()); mailMessage.setFrom(from); // 创建邮件的接收者地址，并设置到邮件消息中 Address[] tos = null; String[] receivers = mailInfo.getReceivers(); if (receivers != null){ // 为每个邮件接收者创建一个地址 tos = new InternetAddress[receivers.length + 1]; tos[0] = new InternetAddress(mailInfo.getToAddress()); for (int i=0; i<receivers.length; i++){ tos[i+1] = new InternetAddress(receivers[i]); } }else { tos = new InternetAddress[1]; tos[0] = new InternetAddress(mailInfo.getToAddress()); }                         // 将所有接收者地址都添加到邮件接收者属性中 mailMessage.setRecipients(Message.RecipientType.TO, tos);  mailMessage.setSubject(mailInfo.getSubject()); mailMessage.setSentDate(new Date());// 设置邮件内容 Multipart mainPart = new MimeMultipart(); BodyPart html = new MimeBodyPart(); html.setContent(mailInfo.getContent(), "text/html;

MyAuthenticator 类

package com.example.mailtestdemo;import javax.mail.Authenticator;import javax.mail.PasswordAuthentication;public class MyAuthenticator extends Authenticator{String userName = null;String password = null;public MyAuthenticator(){}public MyAuthenticator(String userName,String password){this.userName = userName;this.password = password;}protected PasswordAuthentication getPasswordAuthentication(){return new PasswordAuthentication(userName,password);}}

MainActivity 类，使用上面3个类，实现发邮件

package com.example.mailtestdemo;import com.example.mailtestdemo.MultiMailsender.MultiMailSenderInfo;import android.os.Bundle;import android.os.StrictMode;import android.annotation.SuppressLint;import android.app.Activity;public class MainActivity extends Activity {@SuppressLint({ "NewApi", "NewApi" })@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);if (android.os.Build.VERSION.SDK_INT > 9) {StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();StrictMode.setThreadPolicy(policy);// 这个类主要是设置邮件MultiMailSenderInfo mailInfo = new MultiMailSenderInfo();mailInfo.setMailServerHost("smtp.163.com"); // smtp.qq.com,smtp.sohu.com,smtp.163.commailInfo.setMailServerPort("25"); // smtp 端口：25mailInfo.setValidate(true);mailInfo.setUserName("[e-mail]");mailInfo.setPassword("xxxx");// 您的邮箱密码mailInfo.setFromAddress("[e-mail]");mailInfo.setToAddress("[e-mail]");// mailInfo.setToAddress("[e-mail]");// mailInfo.setToAddress("[e-mail]");// mailInfo.setToAddress("[e-mail]");mailInfo.setSubject("设置邮箱标题");mailInfo.setContent("设置邮箱内容");String[] receivers = new String[]{"[e-mail]"};String[] ccs = receivers;mailInfo.setReceivers(receivers);mailInfo.setCcs(ccs);// 这个类主要来发送邮件MultiMailsender sms = new MultiMailsender();sms.sendTextMail(mailInfo);// 发送文体格式MultiMailsender.sendHtmlMail(mailInfo);//发送html格式MultiMailsender.sendMailtoMultiCC(mailInfo);//发送抄送}}}

这个项目需要导入activation.jar，additionnal.jar，mail.jar，把这三个jar复制到项目下的libs文件夹下
