android basic sqlite update statement error

I would like to update only address and phone in sqlite. How can i solve the db.update?

My KEY_ID always is 1 because im only having one row in database

public void updatecontact(String address, String phone){
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put(KEY_ADDRESS, address);
    values.put(KEY_PHONE, phone);

    String userid="1";
    return db.update(TABLE_LOGIN, values, KEY_ID "= userid", null);

}

What should i do in this to correct it inwhereClause and whereArgs?

return db.update(TABLE_LOGIN, values, whereClause, whereArgs);

do it possible to use KEY_EMAIL = KEY_EMAIL?
