In today's tutorial, we are going to learn about If Statements. We are also going to work with a list picker to make a calculator.
A listpicker creates a list of items for a user to... pick. We need to add these items to our listpicker.
Now we want our calculator to work. Lets add some blocks.
Test out your app. You should be able to add and subtract numbers now.
Here are some hard things to try to do. If you don't want to try any of these, or are finished:
Regular Challenge: Add multiplication and division functions to your app.
Super Hard Challenge: Add exponents and roots functions to your app.
Developers Challenge: Make a copy new of your Day3 and rename it to a real app name. Change the background color, button and text fields layouts to be more ascetically pleasing. Make a icon for the app. Add your "company name" to the app. Basically, make this app look and feel like a professional app that belongs on a phone. Package your app to your phone.
