上一个邮件的接受,因为不当操作,保存未完成,一切东西都得从头开始那就先从邮件发送来吧。

先下我们做一个较为简单的邮件发送

以下是源代码:相信看过上篇文章所给连接的人,对于javamail应该都有了一定的认识和了解

sendMail

package mi.email.activity;

import java.io.IOException;
import java.util.Properties;

import javax.mail.Address;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import mi.learn.com.R;
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class SendMail extends Activity {
    private Button btnClick;
    private EditText txtToAddress;
    private EditText txtSubject;
    private EditText txtContent;
    private static final String SAVE_INFORMATION = "save_information";
    String username;
    String password;

    public void SendMail() throws MessagingException, IOException {
        // 用sharedpreference来获取数值
        SharedPreferences pre = getSharedPreferences(SAVE_INFORMATION,
                MODE_WORLD_READABLE);
        String content = pre.getString("save", "");
        String[] Information = content.split(";");
        username = Information[0];
        password = Information[1];

        // 该部分有待完善!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
        Properties props = new Properties();
        props.put("mail.smtp.host", "smtp.sina.com");// 存储发送邮件服务器的信息
        props.put("mail.smtp.auth", "true");// 同时通过验证
        // 基本的邮件会话
        Session session = Session.getInstance(props);
        session.setDebug(true);// 设置调试标志
        // 构造信息体
        MimeMessage message = new MimeMessage(session);

        // 发件地址
        Address fromAddress = null;
        // fromAddress = new InternetAddress("sarah_susan@sina.com");
        fromAddress = new InternetAddress(username);
        message.setFrom(fromAddress);

        // 收件地址
        Address toAddress = null;
        toAddress = new InternetAddress(txtToAddress.getText().toString());
        message.addRecipient(Message.RecipientType.TO, toAddress);

        // 解析邮件内容

        message.setSubject(txtSubject.getText().toString());// 设置信件的标题
        message.setText(txtContent.getText().toString());// 设置信件内容
        message.saveChanges(); // implicit with send()//存储有信息

        // send e-mail message

        Transport transport = null;
        transport = session.getTransport("smtp");
        transport.connect("smtp.sina.com", username, password);

        transport.sendMessage(message, message.getAllRecipients());
        transport.close();
        System.out.println("邮件发送成功!");

    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.send_email);

        txtToAddress = (EditText) findViewById(R.id.txtToAddress);
        txtSubject = (EditText) findViewById(R.id.txtSubject);
        txtContent = (EditText) findViewById(R.id.txtContent);

        txtToAddress.setText("自己的邮箱@qq.com");
        txtSubject.setText("Hello~");
        txtContent.setText("你好,我在做程序呢~");

        btnClick = (Button) findViewById(R.id.btnSEND);
        btnClick.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                try {
                    SendMail();
                } catch (MessagingException e) {

                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }

        });

    }

}
