Android Send Mail Method Example detailed _android

The example in this article describes how Android sends mail. Share to everyone for your reference, specific as follows:

The ability to send mail in Android phones is also essential. How do you implement it? The following is illustrated in a simple example.

The procedure is as follows:

Import Java.util.regex.Matcher;
Import Java.util.regex.Pattern;
Import android.app.Activity;
Import android.content.Intent;
Import Android.os.Bundle;
Import android.view.KeyEvent;
Import Android.view.View;
Import Android.view.View.OnClickListener;
Import Android.view.View.OnKeyListener;
Import Android.widget.Button;
Import Android.widget.EditText;
 public class A04activity extends activity {private EditText reciver,cc,subject,body;
 Private Button B;
 Private string[] Strreciver;
 Private string[] STRCC;
 Private String strbody;
  Private String strsubject; /** called the activity is a.
    * * @Override public void onCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    Setcontentview (R.layout.main);
    b= (Button) Findviewbyid (R.id.button); 
    B.setenabled (FALSE);
    B.settext ("Send Mail");
    Reciver= (EditText) Findviewbyid (r.id.reciver);
    subject= (EditText) Findviewbyid (r.id.subject);
    Cc= (EditText) Findviewbyid (r.id.cc); Body= (EditText) Findviewbyid (r.id.body); Reciver.settext ("Please enter the email address");
    Set the default field Body.settext ("Please enter the message content");
    Subject.settext ("Please enter subject");
    Cc.settext ("Please enter the Mail field"); Click the edit box to enter the editable state reciver.setonclicklistener (new Onclicklistener () {@Override public void OnClick (View v) {//TOD
  O auto-generated Method Stub Reciver.settext ("");
    }
    }); Cc.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {//TODO auto-generated method s
  Tub Cc.settext ("");
    }
    }); Subject.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {//TODO auto-generated met
  Hod stub Subject.settext ("");
    }
    });  Body.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {//TODO auto-generated method
  Stub Body.settext ("");
    }
    });
  Reciver.setonkeylistener (New Onkeylistener () {@Override public boolean onkey (View v, int keycode, keyevent event) { TODO Auto-generated Method StUB if (Isemail (Reciver.gettext (). toString ()) {b.setenabled (true);
  } else{b.setenabled (false);
  return false;
    }
    }); B.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {//TODO auto-generated Method St
  UB Strreciver=new String[]{reciver.gettext (). toString ()};
  Strcc=new String[]{cc.gettext (). toString ()};
  Strsubject=subject.gettext (). toString ();
  Strbody=body.gettext (). toString ();
  Intent i=new Intent (Android.content.Intent.ACTION_SEND);
  I.putextra (Android.content.Intent.EXTRA_EMAIL, strreciver);
  I.putextra (Android.content.Intent.EXTRA_CC, STRCC);
  I.putextra (Android.content.Intent.EXTRA_SUBJECT, strsubject);
  I.putextra (Android.content.Intent.EXTRA_TEXT, strbody);
  StartActivity (Intent.createchooser (i, Getresources (). getString (R.string.str_message)));
  }
    }); public static Boolean Isemail (String s) {string expression= "^[a-za-z][\\w\\.-]*[a-za-z0-9]@[a-za-z0-9][\\w\\.-]*[a- Za-z0-9]\\. [A-za-z] [a-za-Z\\.]
   *[a-za-z]$ ";
   Pattern p=pattern.compile (expression);
   Matcher M=p.matcher (s);
  return m.matches ();

 }
}

Res/layout/main.xml is as follows

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= "http://schemas.android.com/apk/res/" Android "Android:layout_width=" Fill_parent "android:layout_height=" fill_parent "android:orientation=" vertical " > <textview android:layout_width= "fill_parent" android:layout_height= wrap_content "android:text=" @str Ing/hello "/> <button android:id= @+id/button" android:layout_width= "Fill_parent" Android:layout_heig ht= "Wrap_content"/> <edittext android:id= "@+id/reciver" android:layout_width= "Fill_parent" Andro
    id:layout_height= "Wrap_content"/> <edittext android:id= "@+id/cc" android:layout_width= "Fill_parent" android:layout_height= "Wrap_content"/> <edittext android:id= "@+id/subject" android:layout_width= "Fill_parent" android:layout_height= "wrap_content"/> <edittext android:id= "@+id/body" Android:la Yout_width= "Fill_parent" android:layout_height= "Wrap_content"/> </LinearLayout>

 

This is one of the ways you can implement the Send mail feature in Android, and there are two other ways to do this:

Method One:

Uri uri=uri.parse ("mailto:1650***185@qq.com");
Intent i=new Intent (Intent.action_sendto,uri);
StartActivity (i);

Method Two:

Intent i=new Intent (intent.action_send);
String[] tos={"1650***185@qq.com"};
String[] ccs={"7885***158@qq.com"};
I.putextra (Intent.extra_emall,tos);
I.putextra (INTENT.EXTRA_CC,CCS);
I.putextra (Intent.extra_text, "Mail Content");
I.putextra (Intent.extra_subject, "mail Subject");
I.settype ("message/rfc822");
StartActivity (Intent.createchooser (i, "your Mail"));

If you want to add an attachment to a message that you send, you can write this:

Intent i=new Intent (intent.action_send);
I.putextra (Intent.extra_subject, "mail Subject");
I.putextra (Intent.extra_stream, "File:///sdcard/xyz.mp3");
StartActivity (Intent.createchooser (i, "your Mail"));
