  Lab 4: Potato Calorie Count (source: https://www.verywell.com/how-many-calories-in-a-baked-potato-2506867) Design an app that allows the user to determine the number of calories in a baked potato. The app should have a Spinner in which the the user can enter the size of the potato (between 5 and 12 ounces). Next the app should have a second Spinner by which the user can select one for the toppings. The app should also have a Button, and TextView for displaying the answer (number of calories). When the user clicks the button, determine the size of and topping on the potato and display the corresponding number of calories. There are 25 calories for each ounce in a potato. The possible toppings are: (Nothing, Butter, Sour Cream, Chili) which correspond to additional calories of (0, 100, 60, 75) respectively. If the user changes the size of the potato or the topping, then your app should clear out the calorie count. Submit the .xml file for the layout, the .kt files, and if-used to populate a spinner the strings.xml (zipped up).

• Wednesday:
  
  Dog_kotlin.zip Uses a ImageView. Also shows a Kotlin when (which is like a switch statement).
  
  
  
  
  
  Dog2_kotlin.zip Replaces the when code above with some string methods that convert a name like "Border Collie" to "border_collie" which is the corresponding drawable resource name.
  
  Dog3_kotlin.zip Adds a parallel array with dog colors to the strings.xml file. When the dog is selected from the Spinner, its corresponding picture is displayed in am ImageView and its corresponding colors displayed in a TextView.
  
  Dog4_seekbar.zip adds a SeekBar widget
  
  Lab 5: Choose your own subject
  
  Create an app like the one above. You choose the subject: sports, art, Pokemon, movies, whatever. Have a set of images and at least three parallel arrays. One set of data goes into a spinner and the other two in TextViews. When the user selects a new item from the spinner, the image and data displayed should change accordingly.
