CSC 349: Week of 9/18/17

CSC 349: The Week beginning Sept. 18

Homework:

First Roll of Yahtzee
Have an app with 5 ImageViews and a Button. When the user clicks the button, your app should simulate the rolling of five dice (select an array of five random integers in the range 1 to 6 (inclusive).
```
		 Random rand = new Random();
		 int die = rand.nextInt(6) + 1;
		
```
It should display the corresponding images. You can use Dice.zip or find images you like better.

Due: Sept. 26
Tuesday:

Dog.zip Place the image files in the res/drawable folder. Place activity_main.xml in the res/layout folder. Place strings.xml 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 one takes adavantage 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. (I think for this one, I will ask you to demo it for me.)

Due: Sept. 26
Thursday:

ReadRaw.ppt
ReadRaw.zip Layout has Button and TextView. A raw folder was created in the res folder and a (plain) text file has been placed in it. When the button is clicked, the file is read and its content displayed in the TextView.

ReadRandomRaw.zip There are now four files (Shakespeare's Sonnets 15 through 18). When the button is clicked a number between 15 and 18 is chosen (pseudo) randomly and the corresponding file is read and displayed.

ReadRandomRawDada.zip Split the sonnet into individual words. Rearrange the words at random -- making a Dada poem out of a Shakespearean Sonnet.

ReadFileParseDataMakeArrays.zip Parsing a data file and starting to make parallel arrays from it.

Song Lyrics Lab
- Have two parallel arrays of song titles and artist names (and possibly a third array with song lyrics filenames).
- This time use Java code arrays and not xml string-value arrays.
- Have a bunch of text files (at least 4) with lyrics in a res/raw folder.
- Have the song titles loaded into a spinner.
- When the user changes the spinner item, display the corresponding artist's name and the lyrics of that song read from the text file.
