Color Activity Assignment 3

Notes

Implements a lot of what we learned in class but makes some small changes mostly in relation to functions implemented in a spinner view that isn't in a list view. List view typically uses things like onClickListener instead of onItemSelected.

Docstring - MainActivity

@fun onItemSelected(): Changes the background of the view upon selecting an item from the spinner. See comments on ItemsAdapter to see how the custom adapter accepts colors.

@fun onNothingSelected(): setOnItemSelectedListener requires that you implement this or it breaks similarly to how when you extend base adapter you must add and override 4 items requested even though you don't actually ever use getItemID.

@param ((TextView) spinnerView.getSelectedView()): When the item is actually selected, we want to make sure the font is the color the background changes to.

Docstring - ColorAdapter

@fun ColorAdapter(): It takes in three things

1. context - Context represents (provides a handle to) the application environment. Can be obtained from several sources, but capabilities vary.
2. colors - Is what will be used to determine the color of the layout in the MainClass and also the font color of the item inside of the TextView
3. items - The actual string that will be represented in the spinner/textview.

@import Color: Color allows you to pass colors in a variety of ways. In my implementation I use its parseColor function to pass a string that represents a color in hex format.
