[android-developers] Re: HOw to extract only number

2012-03-08 Thread Marius Merkevicius
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.
