text1.contains checks if a string is found in text1.

If it's an edittext just Change the input_type to numbers so the user can only Input numbers (or decimal numbers if you like).

Otherwise do a loop and check the characters in that string with isNumber

Hi, you should use a Matcher to see if there is any char not numeric.

my users can enter numbers or strings into textfiled. I dont want to limit them to numbers only. I want to do stg if there are only numbers and do another thing if not. Maybe i can use the loop example. ty

isnumber(text1.text) works for me . Thanks !
