這篇文章主要介紹了android實現自動發送郵件的方法,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
需要添加activation.jar,additionnal.jar和mail.jar這三個包
首先是一個EmailSender類
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 EmailSender { private Properties properties; private Session session; private Message message; private MimeMultipart multipart; public EmailSender() { super(); this.properties = new Properties(); } public void setProperties(String host,String post){ //地址 this.properties.put("mail.smtp.host",host); //端口號 this.properties.put("mail.smtp.post",post); //是否驗證 this.properties.put("mail.smtp.auth",true); this.session=Session.getInstance(properties); this.message = new MimeMessage(session); this.multipart = new MimeMultipart("mixed"); } /** * 設置收件人 * @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); } /** * 設置郵件 * @param from 來源 * @param title 標題 * @param content 內容 * @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); //純文本的話用setText()就行,不過有附件就顯示不出來內容了 MimeBodyPart textBody = new MimeBodyPart(); textBody.setContent(content,"text/html;charset=gbk"); this.multipart.addBodyPart(textBody); } /** * 添加附件 * @param filePath 文件路徑 * @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); } /** * 發送郵件 * @param host 地址 * @param account 賬戶名 * @param pwd 密碼 * @throws MessagingException */ public void sendEmail(String host,String account,String pwd) throws MessagingException{ //發送時間 this.message.setSentDate(new Date()); //發送的內容,文本和附件 this.message.setContent(this.multipart); this.message.saveChanges(); //創建郵件發送對象,并指定其使用SMTP協議發送郵件 Transport transport=session.getTransport("smtp"); //登錄郵箱 transport.connect(host,account,pwd); //發送郵件 transport.sendMessage(message, message.getAllRecipients()); //關閉連接 transport.close(); } }
下面是mainactivity代碼
import javax.mail.MessagingException; import javax.mail.internet.AddressException; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class MainActivity extends Activity { private Button btnOK; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btnOK = (Button) findViewById(R.id.button); btnOK.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { // sendEmail(); //耗時操作要起線程...有幾個新手都是這個問題 new Thread(new Runnable() { @Override public void run() { try { EmailSender sender = new EmailSender(); //設置服務器地址和端口,網上搜的到 sender.setProperties("smtp.163.com", "25"); //分別設置發件人,郵件標題和文本內容 sender.setMessage("你的163郵箱賬號", "EmailSender", "Java Mail !"); //設置收件人 sender.setReceiver(new String[]{"收件人郵箱"}); //添加附件 //這個附件的路徑是我手機里的啊,要發你得換成你手機里正確的路徑 // sender.addAttachment("/sdcard/DCIM/Camera/asd.jpg"); //發送郵件 sender.sendEmail("smtp.163.com", "你的163郵箱賬號", "你的郵箱密碼");//<span >sender.setMessage("你的163郵箱賬號", "EmailS//ender", "Java Mail !");這里面兩個郵箱賬號要一致</span> } catch (AddressException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (MessagingException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }).start(); } }); } }
