String.matches - Regular Expression

[paulac...@gmail.com]

Hi, I've building a Android app in which I have to validate some textFields' contents.
I've tried to use String.Matches, but it seems that Android don't support it. How could I validate this data?

Thanks in advance.

Hi,
we don't support regex at the moment and some of the more elaborate string methods (e.g. matches, split etc.). This is planned for the future but isn't there yet.
At the moment you will need to write the logic in Java rather than use a regex e.g. indexOf(x) to verify the existence of a char.

Alternatively you can incorporate one of the open source regex implementations from the web.

If you're using a platform that has a native browser component (i.e.
Android or iOS) you can also use Javascript for regex via the
BrowserComponent.executeAndReturnString() method.

I'm trying to check my expression with charAt.
So, I get the character at the index that I want.
But in some points I have to convert it to int, to check if its a number.
So, I tried to do this:

Integer.parseInt(Character.toString(text.charAt(i)));

But it seems that I also cant't use Character.toString. I have to check all possibilities in Codename One??

Thanks, again. (:

Just go by the CodenameOne API docs:
https://codenameone.googlecode.com/svn/trunk/CodenameOne/javadoc/java/lang/Character.html

Notice that there is no static toString() method in the Character class.

Yeah, you are completely right. Sorry for the dumb question.
