基于Android的手机邮件收发（JavaMail）之四（邮件的发送）

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();
}
}

});

}

}

界面效果图：





ps:内容比较粗糙，后续还需要改善！
