點擊按鈕即可全自動發送電子郵件在android系統

Question

我有一個XML文件，用戶將輸入一個電子郵件到它，那麼當點擊提交按鈕，我希望應用程序的具體內容，該電子郵件自動發送電子郵件。 。

任何好的教程或例子我可以從中獲得幫助？

package com.example.emailtest; 
import android.os.Bundle; 
import android.app.Activity; 
import android.view.Menu; 
import android.view.View; 
import android.widget.Button; 

public class main extends Activity{ 
public Button bsend; 
public Mail m; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    bsend=(Button) findViewById(R.id.button1); 
    bsend.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      Mail mail = new Mail(); 
       try { 
        mail.send(); 
       } catch (Exception e) { 
        e.printStackTrace(); 
       }} 

    }); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

} 

logcat的

Answer 1

在我來說，我用Java郵件API和下面你的代碼可以使用。請加如用戶名，密碼，電子郵件ID等使用本教程http://www.jondev.net/articles/Sending_Emails_without_User_Intervention_%28no_Intents%29_in_Android

public class Mail extends javax.mail.Authenticator { 
    private String _user; 
    private String _pass; 

    private String[] _to ; 
    private String _from; 

    private String _port; 
    private String _sport; 

    private String _host; 

    private String _subject; 
    private String _body; 

    private boolean _auth; 

    private boolean _debuggable; 

    private Multipart _multipart; 


    public Mail() { 
    _host = "smtp.gmail.com"; // default smtp server 
    _port = "465"; // default smtp port 
    _sport = "465"; // default socketfactory port 

    _user = "username"; // username 
    _pass = "password"; // password 
    _from = "emailsentfrom@gmail.com"; // email sent from 

    _to = new String[] {"toemail@gmail.com"}; 
    _subject = "subject"; // email subject 
    _body = "test"; // email body 

    _debuggable = false; // debug mode on or off - default off 
    _auth = true; // smtp authentication - default on 

    _multipart = new MimeMultipart(); 

    // There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added. 
    MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap(); 
    mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html"); 
    mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml"); 
    mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain"); 
    mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed"); 
    mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822"); 
    CommandMap.setDefaultCommandMap(mc); 
    } 
    public Mail(String user, String pass) { 
    _user = user; 
    _pass = pass; 
    } 

    public boolean send() throws Exception { 
    Properties props = _setProperties(); 

    if(!_user.equals("") && !_pass.equals("") && _to.length > 0 && !_from.equals("") && !_subject.equals("") && !_body.equals("")) { 
     Session session = Session.getInstance(props, this); 

     MimeMessage msg = new MimeMessage(session); 

     msg.setFrom(new InternetAddress(_from)); 

     InternetAddress[] addressTo = new InternetAddress[_to.length]; 
     for (int i = 0; i < _to.length; i++) { 
     addressTo[i] = new InternetAddress(_to[i]); 
     } 
     msg.setRecipients(MimeMessage.RecipientType.TO, addressTo); 

     msg.setSubject(_subject); 
     msg.setSentDate(new Date()); 

     // setup message body 
     BodyPart messageBodyPart = new MimeBodyPart(); 
     messageBodyPart.setText(_body); 
     _multipart.addBodyPart(messageBodyPart); 

     // adding attachment 
     addAttachment("filename");//replace with file name u need 

     // Put parts in message 
     msg.setContent(_multipart); 

     // send email 
     Transport transport = session.getTransport("smtps"); 
     transport.connect(_host, 465,_user, _pass); 
     Transport.send(msg); 

     return true; 
    } else { 
     return false; 
    } 
    } 

    public void addAttachment(String filename) throws Exception { 
    BodyPart messageBodyPart = new MimeBodyPart(); 
    DataSource source = new FileDataSource(filename); 
    messageBodyPart.setDataHandler(new DataHandler(source)); 
    messageBodyPart.setFileName(filename); 

    _multipart.addBodyPart(messageBodyPart); 
    } 

    @Override 
    public PasswordAuthentication getPasswordAuthentication() { 
    return new PasswordAuthentication(_user, _pass); 
    } 

    private Properties _setProperties() { 
    Properties props = new Properties(); 

    props.put("mail.smtp.host", _host); 

    if(_debuggable) { 
     props.put("mail.debug", "true"); 
    } 

    if(_auth) { 
     props.put("mail.smtp.auth", "true"); 
    } 

    props.put("mail.smtp.port", _port); 
    props.put("mail.smtp.socketFactory.port", _sport); 
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
    props.put("mail.smtp.socketFactory.fallback", "false"); 
    props.put("mail.smtp.starttls.enable", "true"); 

    return props; 
    } 

    // the getters and setters 
    public String getBody() { 
    return _body; 
    } 

    public void setBody(String _body) { 
    this._body = _body; 
    } 

    // more of the getters and setters É.. 
} 

必要的細節，寫一個異步任務發送郵件

public class SendTask extends AsyncTask<String, Integer, Integer> { 

private ProgressDialog dialog; 
private Context mContext; 

public SendTask(Context mContext){ 
    this.mContext = mContext; 

} 

protected void onPreExecute() { 
    this.dialog = new ProgressDialog(mContext); 
    this.dialog.setCancelable(false); 
    this.dialog.setMessage("sending"); 
    this.dialog.show(); 
} 

protected Integer doInBackground(String... ids) { 

    Mail mail = new Mail(); 
    try { 
     mail.send(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    return 1; 
} 

}

Answer 2

在XML提交您的按鈕，定義android:onClick="SendMail"

這將調用SendMail functi當你的按鈕被點擊時，在你的活動中。

接着，得到的地方，用戶進入電子郵件主體的EditText視圖的參考。

如：如果您EditText視圖的資源ID是edittext1，然後在你的活動，你需要做到以下幾點：

EditText ed=(EditText)findViewById(R.id.edittext1); 

String emailBody=ed.getText().toString(); 

現在emailBody字符串包含郵件正文的是，用戶鍵入

接下來，你的活動中，你需要定義一個函數SendMail()，如下圖所示：

void SendMail(String body) { 
    String recipient="usrname@mail.com"; 
    String subject="Your subject here"; 
    Intent i = new Intent(Intent.ACTION_SEND); 
    i.setType("message/rfc822"); 
    i.putExtra(Intent.EXTRA_EMAIL , recipient); 
    i.putExtra(Intent.EXTRA_SUBJECT, subject); 
    i.putExtra(Intent.EXTRA_TEXT , body); 
    try { 
     startActivity(Intent.createChooser(i, "Send mail...")); 
    } catch (android.content.ActivityNotFoundException ex) { 
    Toast.makeText(MyActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show(); 
    } 
} 

這種方法幫助了我，希望它也能幫助你。
