boolean hasPhone = (Integer.parseInt(people.getString(
                       people.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0);  
 if (hasPhone)  
 {
     Cursor pCur = cr.query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
                   null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
                   new String[]{id}, null);
     while (pCur.moveToNext()) {
        // process phone numbers
     } 
     pCur.close();
 }
