I have successfully created an App which uses CheckBoxes, NumberPickers and TextViews (for each number picker). I also have a Toastwhich now displays the number of each item checked, but the amount is static at the moment - i.e it only shows the single item price.
I want to use the NewVal from each number picker iteration to multiply the price. How do I take the int newVal number and use it in the Listener which contains the Toast?
Here's the code:
ps if you look at the first line of result.append, you'll see what I'm trying to do with newVal for EACH related number picker..
