Hi All man! :)

My question is simple, but I can not find answer... :(

How can I write ONLY numbers in EditText? In essence, I have to write only numbers and not letters...

Situation:

I write any numbers in editText and I've as result in label (like addition, division ecc).
I write any word or letter and I've as result a messagebox like "You can write only numbers!"

Any help is welcome :)

Thanks
Michele71

I am preparing a small script which calculates the mass, density and volume of an object, like a small calculator. I would like to speed up the calculation. The real problem is NOT to write letters in dell'Edittext ;)

Thanks anyway for your suggestion
