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

i have set this two lines in the textedit from my your_class.xml

android:inputType="numberDecimal"
android:digits="0123456789."

the first line is for setting the keybordart (only numbers and the dot). the second line only allows predetermined characters.
