Watch the video Radio Buttons: Android Programming (by DrBFraser). Then redo your cooking steak lab, but this time generate the RadioButtons dynamically as shown in the video. Zip up the "main" folder of the project and send it.

Due: Feb. 6
Tuesday:

OneSeekBar.zip Demos a single SeekBar widget.

RGB_Seekbars.zip Demos a set of SeekBar widgets.

ProfRatingBar.zip Demos a set of RatingBar widgets.

Lab: Toward an Equalizer Interface

Have a set of seek bars (at least six) that can be used to control the values of an array. Each value in the array can be in the range -12 to 12. The values should be displayed on the interface as well as stored in the (java) array. The numbers (32, 64, 125 etc.) seen above are not the values but rather are labels indicating the frequency range(?) to which each value corresponds.

Due: Feb. 6
Thursday:

RGB_Seekbars_2.zip (redo SeekBar app using child-parent relationships to determine relationship between "neighboring" SeekBars and TextViews)

Dog.zip Place the image files in the res/drawable folder. Place string array of dog names in res/values. The design has a Spinner -- loaded from a string array of dogs in the strings.xml file -- and an ImageView. When the user changes the selected spinner value the image resource of the image view is changed. (The user sees the selected dog).

Dog2.zip The previous version had an obnoxious switch statement to connect the user's selected dog (e.g. Lhasa Apso) to the resourse R.drawable.lhasa_apso with cases looking like
```
				case "Lhasa Apso":
					ivDog.setImageResource(R.drawable.lhasa_apso);
					break;		
		
```
But this new version takes advantage of the relationship between the resource name and the dog breed name.

Dog3.zip Adds a TextView to the layout, a "parallel array" to the strings.xml, and code to display the corresponding item from the new array when the user changes the selected value in the spinner.

Lab: 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.
