Android - Showing Phonebook contacts and selecting one

Question

How can I show the list of contacts in phonebook on a click of a button and then select one of the contacts from it and then retrieve its contact number?

I don’t want to make my custom list. Is there a way to use Android's built-in functionality?

TRY THIS-->

   setContentView(R.layout.main);

   contactNumber = (TextView)findViewById(R.id.contactnumber);

   Button buttonPickContact = (Button)findViewById(R.id.pickcontact);
   buttonPickContact.setOnClickListener(new Button.OnClickListener(){

   @Override
    public void onClick(View arg0) {
   // TODO Auto-generated method stub


   Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
   intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
   startActivityForResult(intent, 1);             


    }});
   }

   @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

   if(requestCode == RQS_PICK_CONTACT){
   if(resultCode == RESULT_OK){
    Uri contactData = data.getData();
    Cursor cursor =  managedQuery(contactData, null, null, null, null);
    cursor.moveToFirst();

      String number =       cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));

      //contactName.setText(name);
      contactNumber.setText(number);
      //contactEmail.setText(email);
     }
     }
     }
     }

EDIT XML ADDED;

      <?xml version="1.0" encoding="utf-8"?>
      <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:orientation="vertical" >

      <Button
        android:id="@+id/pickcontact"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Pick Contact" />

      <TextView
       android:id="@+id/contactnumber"
       android:layout_width="match_parent"
       android:layout_height="wrap_content" />

 </LinearLayout>
