allow only number and period(.) in edit text in android

Question

i want to allow only numbers and period(.) in a android edit text. How to do this .. can any body help?

Answer 1

Use android:inputType="numberDecimal".

EDIT: Saw that you later wrote that you want to use this as an editText for IP numbers. Don't use my solution then. For "digits" (not numbers) plus the dot this won't work.
