what's the best way to apply a mask to an EditText on Android?

Question

what's the best way to mask a EditText on Android?
I Would like my EditText to behave like this decimal number input here. Is there a easy way to do this?

Answer 1

You have to programmatically set an InputFilter on your EditText by setFilters.

From the documentation:

InputFilters can be attached to Editables to constrain the changes that can be made to them.

You can even change the users input, for example by adding a decimal point which is what you want if I get you correctly.
