You can achieve it like this     
public class Abc extends Activity{
EditText kimeTxt;
Intent i;                                  
Bundle b ;    
@Override  
protected void onCreate(Bundle savedInstanceState) {
//TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.add_course);
kimeTxt= (EditText)findViewById(R.id.emailid);
}
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
try {
if (resultCode == Activity.RESULT_OK) {
//Get data
Uri contactData = data.getData();
//Cursor
Cursor cur = managedQuery(contactData, null, null, null, null);
ContentResolver contect_resolver = getContentResolver();
//List
if (cur.moveToFirst()) {
String id = cur
.getString(cur
.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
Cursor phoneCur = contect_resolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
Cursor emailCur = contect_resolver.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = ?", new String[] { id }, null);
if (phoneCur.moveToFirst()) {
name = phoneCur
.getString(phoneCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
no = phoneCur
.getString(phoneCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
while (emailCur.moveToNext()) {
//This would allow you get several email addresses
//if the email addresses were stored in an array
email = emailCur
.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
if (email != null) 
{
seciliEmail = email;
} else {
Toast.makeText(EpostaIletActivity.this,
"Kişinin eposta hesabı bulunmamaktadır.",
Toast.LENGTH_SHORT);
Log.w("Error: ", "Kişinin eposta hesabı yok.");
}
}
Log.e("Phone no & name & email :***: ", name + " : " + no + ":" + email);
//txt.append(name + " : " + no + "\n");
id = null;
name = null;
no = null;
seciliEmail = "xxx";
phoneCur = null;
emailCur.close();
}
//can set email id here 
kimeTxt.setText(email);
contect_resolver = null;
