I am trying to create a method to check for unique usernames. For example, if the username
JOHN exists, someone else shouldn’t pick the username
John. My only problem is that I can’t find the good regex for it. I tried the following:
ParseQuery query = ParseUser.getQuery(); String regex = nickname.getText().toString().toLowerCase(); query.whereMatches("username", regex, "i");
But this also gives the users who have the username
Johnny. How can I only find the username
John case insensitive?
