you can also try this pattern: "\\d+\\.?\\d[0-2]"

explanation:

\\d+ - look for 1 or more digits between 0 and 9

\\.? - there can be a dot, but does not have to be (? = 0 or 1)

\\d[0-2] - after the dot can be up to 2 digits between 0 an 9

with this pattern you will return 2300.00 from ej. :USD $ 2300.00

I just put this to my string:

v.getText().toString().replaceAll("[^\\d.]", "");
