Android Shopping Cart Tutorial Part 3

In this part of the Android Shopping Cart Tutorial we will add prices, and calculate the total price for the purchase.

This tutorial is part of a series about building an android based shopping cart, and will build off of existing code and concepts discussed in Android Shopping Cart Tutorial and Android Shopping Cart Tutorial Part 2.

Step 1. Prices for Products

In our previous tutorials we learned how to display different products, add them to the cart, and even change the quantity of those products. Now we must add another crucial component, the price.

If you look back at the previous tutorials, our Product object already contains price information, and our initial catalog is setting prices--these prices simply are not being displayed in the app anywhere.
