[android-developers] Re: HOw to extract only number
Ok first things first.
1) As I develop, always use try/catch on these kind of operations, so they
only show warnings, but wouldn't force-quit program.
2) Try putting a number only format in youre EditText. (I dont remember
correctly but that's android:inputType:"number" or
android:inputMethod:"number". That will prevent user from entering symbols,
only numbers.
3) Try parsing options, here is a nice and simple examples to start to.

Have fun :)
