Write an Android app that simulates a traffic light. It displays a label and a button. The label represents the current color of a traffic light and can be red, green, or yellow. When the user clicks on the button, the label cycles to the next color and simulates running the traffic light. You should look at the documentation of the View class to figure out how to change the color of a View programmatically. The two components should be centered vertically. Include a Model.
