Java regex in android

Question

if someone could help me with my regex-problem, it would be aweful !

I have an EditText and the charakters which are allowed to be typed in are the following:

A-Z, Ä, Ö, Ü (only uppercases), and ß

I'm grateful for any help!

I think you mean awesome. You want to solicit, not discourage, assistance. — Bathsheba, Jul 09 '15 at 08:37
Have you tried yourself with some regex before? If so please show what you did so far — André Schild, Jul 09 '15 at 08:39

Use [A-ZÄÖÜß]+ as your regular expression.

Replace + with * if you want to support zero length strings.

(You might want to use \u notation in your source code in place of the special characters to help code editors and source control systems.)

how do you mean \u in place of the special characters? – Marcel Bialek Jul 09 '15 at 08:51

You mean something like this?

Pattern p = Pattern.compile("^[A-ZÄÖÜß]+$");
Matcher m = p.matcher(inputString);
if(m.matches() {
    //Do whatever you need to do when the pattern matches.
}
