Android: Remove digits from string

I have a string with a format like "integer1_text integer2" (ex. "23_home 2" ).

I would like to remove the integer1, or replace it with an empty string (so keep only "home 2").

Integer1 is a number from 0 to 1000 and i just want to remove it.

I have tryed to do something like string=mystring.replaceAll("[^0-9]+"_",""); but is not working correctly.

Any idea please? thanks

There are just a few small mistakes in your regex, try:

mystring.replaceAll("^[0-9]+_", "");

you can use indexOf("_");

Returns the index within this string of the first occurrence of the specified character.

and use substringIint startIndex, int endIndex); to extract the String you need, with startIndex the index returned by indexOf
