how to set text on "to" textarea in email activity

i have made an activity

at subscribe button, i have to send email to some default email for which my code is:
package sditm.app;

import android.R.string;
 import android.app.Activity;
 import android.content.ContentValues;
 import android.content.Intent;
 import android.database.Cursor;
 import android.database.sqlite.SQLiteDatabase;
 import android.os.Bundle;
 import android.text.Html;
 import android.view.View;
 import android.view.View.OnClickListener;
 import android.widget.Button;
 import android.widget.EditText;
 import android.widget.Toast;
 
 public class subscribeActivity extends Activity {
 /** Called when the activity is first created. */
 EditText name,age,address;
 databaseforsubscribe addressBook;
 
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.subscribe);
 
     Button store = (Button)findViewById(R.id.button1);
 
 
     name=(EditText)findViewById(R.id.editText1);
     age=(EditText)findViewById(R.id.editText2);
     address=(EditText)findViewById(R.id.editText3);
 
 
     addressBook = new databaseforsubscribe(this,"addressDB",null,2);
 
     store.setOnClickListener(new OnClickListener() {
         public void onClick(View v) {
             // TODO Auto-generated method stub
             String s=new String();
             String m=new String();
             String n=new String();
             s=name.getText().toString();
             m=age.getText().toString();
             n=address.getText().toString();
             Intent i = new Intent(Intent.ACTION_SEND);
             i.setType("text/plain");
 
             i.putExtra(Intent.EXTRA_EMAIL, "aman4251@gmail.com");
         //  i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"aman4251@gmail.com"});
             i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
             i.putExtra(Intent.EXTRA_TEXT   ,"NAME: "+s+" ; MOBILE: "+m+" ; EMAIL: "+n);
             try {
                 startActivity(Intent.createChooser(i, "Send mail..."));
             } catch (android.content.ActivityNotFoundException ex) {
                 Toast.makeText(subscribeActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
             }
         }
     });
 }
 
 }
 

which open an intent like this

now either i have to set the email id to "To" textbox (and make it uneditable"), or to automatically click on that "send" button so that user dont see this intent and email is send in back ground..
