Case study 2 - ButtonWidget

In this case study, we'll be creating a new Android application that will have a button which that show a new text view when clicked. We'll also be writing UITest for this application:

1. Create a new blank Android application project in Visual Studio, name it ButtonWidget, and click OK:

2. After creating the project, open the Main.axml file from Resources | Layout in Solution Explorer.
3. Then, add a text view and a button to the view from the Toolbox on the left.
4. Give each of these IDs to identify them in the code. You can select them, then show the property window, and give them IDs there:

5. Also, set the visibility of the text view to hidden, because we'll be showing this text only on a button-click:

6. Now, open the MainActivity.cs file from Solution Explorer:

7. In MainActivtiy.cs, add code to show the text view when the button is clicked...
