        if (resultCode == Activity.RESULT_OK) {
            // Uri contactData = data.getData();
            String id = cursor.getString(cursor
                    .getColumnIndex(ContactsContract.Contacts._ID));
            String name = cursor
                    .getString(cursor

                // contact_Id

                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                        null,

                while (pCur.moveToNext()) {
                    // you can store phone in a arrayList
                    destinationPhoneNumber = pCur
                            .getString(pCur
                                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    //
                    enterPhoneNumber.setText(destinationPhoneNumber);
                    Toast.makeText(this,
                            name + " has number " + destinationPhoneNumber,
                            Toast.LENGTH_LONG).show();

You have to first query the Contacts DB like this:

ContentResolver resolvr = getContentResolver();  
Cursor cursor = resolvr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

The resultSet is in cursor.
