Hi! can someone enlighten me why this returns false?

"hello world".matches(Regex("([A-Za-z])"))

because your regex is expecting a single letter from A-z Try using this website (or any similar) if you are new to regular expressions https://regexr.com/

Yeah,

matches

tries to match the entire input, even if that's not really stated in the Kdoc. This returns true:

"hello world".matches(Regex("(.*[A-Za-z].*)"))

Returns true if this char sequence matches the given regular expression.

I see how the choice of words might be confusing to some... For the match you can use even simpler

"[A-z\s]*"

Right! 💡thanks guys 👍

@jermainedilao Please, do not cross-post your messages to different channels. Choose one. And this #android channel is a bad choice for such generic questions

@gildor my bad. Noted!

To add on, I believe there’s a method

contains

to just check if the regex matches any segment for the string. And if you are checking for letters only, you can do

Regex([A-Za-z]*)

(which wouldn’t match hello world due to the space)
