Android 发送电子邮件范例

Android 发送电子邮件范例

1.首先需要3个类库文件

activation.jar
additionnal.jar
mail.jar

网上可以找到的哦，勤快点哈！

2.编写一个发送邮件的操作类 SendMail.java

package com.jinshainfo.bofengbluetoothtool;//QQ 458978 代码参考网络资源修改，亲测好用，不明请联络我import java.io.File;import java.util.Date;import java.util.Properties;import javax.activation.DataHandler;import javax.activation.FileDataSource;import javax.mail.Address;import javax.mail.Message;import javax.mail.MessagingException;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.AddressException;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeBodyPart;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeMultipart;public class SendMail {    private Properties properties;    private Session session;    private Message message;    private MimeMultipart multipart;    public SendMail() {        super();        this.properties = new Properties();    }    public void setProperties(String host, String post) {        this.properties.put("mail.smtp.host", host);        this.properties.put("mail.smtp.post", post);        this.properties.put("mail.smtp.auth", true);        this.session = Session.getInstance(properties);        this.message = new MimeMessage(session);        this.multipart = new MimeMultipart("mixed");    }    /**     * 设置收件人     *      * @param receiver     * @throws MessagingException     */    public void setReceiver(String[] receiver) throws MessagingException {        Address[] address = new InternetAddress[receiver.length];        for (int i = 0; i < receiver.length; i++) {            address[i] = new InternetAddress(receiver[i]);        }        this.message.setRecipients(Message.RecipientType.TO, address);    }    /**     * 设置邮件     *      * @param from     * @param title     * @param content     * @throws AddressException     * @throws MessagingException     */    public void setMessage(String from, String title, String content) throws AddressException, MessagingException {        this.message.setFrom(new InternetAddress(from));        this.message.setSubject(title);        // 纯文本的话用setText()就行，不过有附件就显示不出来内容了        MimeBodyPart textBody = new MimeBodyPart();        textBody.setContent(content, "text/html;charset=gbk");        this.multipart.addBodyPart(textBody);    }    /**     * 添加附件     *      * @param filePath     * @throws MessagingException     */    public void addAttachment(String filePath) throws MessagingException {        FileDataSource fileDataSource = new FileDataSource(new File(filePath));        DataHandler dataHandler = new DataHandler(fileDataSource);        MimeBodyPart mimeBodyPart = new MimeBodyPart();        mimeBodyPart.setDataHandler(dataHandler);        mimeBodyPart.setFileName(fileDataSource.getName());        this.multipart.addBodyPart(mimeBodyPart);    }    /**     * 发送邮件     *      * @param host 地址     * @param account 账户名     * @param pwd 密码     * @throws MessagingException     */    public void sendEmail(String host, String account, String pwd) throws MessagingException {        // 发送时间        this.message.setSentDate(new Date());        // 发送的内容，文本和附件        this.message.setContent(this.multipart);        this.message.saveChanges();        // 创建邮件发送对象，并指定其使用SMTP协议发送邮件        Transport transport = session.getTransport("smtp");        // 登录邮箱        transport.connect(host, account, pwd);        // 发送邮件        transport.sendMessage(message, message.getAllRecipients());        // 关闭连接        transport.close();    }}

在界面调用类里面使用

<pre name="code" class="java">//QQ 458978 代码参考网络资源修改，亲测好用，不明请联络我import com.jinshainfo.bofengbluetoothtool.SendMail;import android.app.Activity;import android.os.AsyncTask;import android.os.Bundle;import android.view.View;import android.widget.Button;public class MainActivity_About extends Activity {Button btnBack;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.aboutactivity);btnBack = (Button) this.findViewById(R.id.button_back_s);btnBack.setOnClickListener(new ClickEvent());}// 按钮事件class ClickEvent implements View.OnClickListener {@Overridepublic void onClick(View v) {if (v == btnBack) {new SVGAsync().execute("");//发送邮件closeAndExit();//退出界面return;}}}public void closeAndExit() {finish();}class SVGAsync extends AsyncTask<String, Integer, Object> {@Overrideprotected void onPreExecute() {super.onPreExecute();}@Overrideprotected Object doInBackground(String... params) {SendMail sender = new SendMail();// 设置服务器地址和端口sender.setProperties("smtp.qq.com", "465");// 465或者587try {sender.setMessage("[e-mail]", "来自Andriod客户端的邮件","系统执行了您预先设置的动作!!!
