Ensuring a user doesn't enter a space in an EditText

Question

I'm using some regex to validate an EditText and am trying to ensure that a user won't enter a space/whitespace. My current regex is: "^[A-Za-z0-9][\\w.-]+$";

Does anyone have any idea? I did a little research and discovered adding in \\s detects spaces but it didn't help.

Thanks for any help!

I'd like to keep the entire validation in this REGEX though, if possible. — Connor McFadden, Oct 21 '14 at 09:01
It is much easier to disallow user to enter space, rather than allowing user enter all characters except _space_ — DnR, Oct 21 '14 at 09:03
You need to use `InputFilter` for your purpose.. This might help : http://stackoverflow.com/questions/3349121/how-do-i-use-inputfilter-to-limit-characters-in-an-edittext-in-android — dreamcoder, Oct 21 '14 at 09:11

If you want to have your regex matching only when the string doesn't contain any spaces you can try:

^[^\s]*$

Are you searching for ^[^\\s]*

Where would this be added into the current regex I have? – Connor McFadden Oct 21 '14 at 09:22
You can use this instead of current regex. – Vijeesh Oct 21 '14 at 09:27

Try this:

^[\S]*$

\S matches any non-whitespace character.
