Magic8Ball Example

Goal:

• Display a Magic8Ball prediction on the screen. Show a different random prediction when the screen is clicked.
  See this Wikipedia article for the 20 Magic8 Ball predictions.

Directions:

• Create an Android project named Magic8Ball.

Modifications: Step 1

1. Add the Magic 8 Ball predictions to the strings.xml file.
2. Modify layout to use a linear layout and display one of the Magic8Ball predictions, for example, "Ask again later.". Set the background color to black and the text color to white, using the colors already defined in colors.xml.  Here is a suggested layout file: activity_main.xml
3. Test the app.

Modifications: Step 2

• Modify the app so that it (1) contains a Prediction class that returns a random Magic8Ball prediction, (2) has an onClick event handler in the activity file so that a new prediction is displayed when the linear layout is clicked. Here are the modified files:  Prediction.java   MainActivity.java

Modifications: Step 3

• Modify the app so that is uses Method 4 to implement the onClick event listener instead of Method 1.
