Delete second dot/comma in EditText

Question

I want to add a few numbers together from an EditText. I want it to work both for european and other countries so it has to work with commas and dots as seperators. The problem is the app crashes if the user accidently puts in 2 or more dots or a dot and a comma. Is there a short way to check and delete the unnecessary seperators? Thanks a lot!

This is my code so far:

android:inputType="number|numberDecimal"
android:digits="0123456789.,"

.replace(",", "."));

Answer 1

This should do the trick,

.replaceAll("\\,+", ".").replaceAll("\\.+", ".")

if there are any commas first one will replace all the commas with dots and the second one will replace all the dots with a one dot

Answer 2

This will replace the whole string with 0. It's not pretty but at least it keeps the app from crashing. I guess this will have to do for now ;)

if (string.getText().toString().matches(". \\.. \\..*")) {string.setText("0");}
