setVisibility not working [duplicate]

I am trying to hide a button if a logged in user is a Donor. I have my code like this.

String typ = user.get("type").toString();
    Log.d("before checking type", typ);

    if (typ == "Donor"){

        ne.setVisibility(View.GONE);
        //ne.setEnabled(false);
    }

In the log, I get the result Donor, so I know the call to the database is working. But the button I need to hide, doesn't hide. Anyone knows why?
