Pak Longs Android Programming Corner for Absolute Beginners - Continued - Part 4 - Display a Vertically Scrolling Rainbow of Colours


The above video shows the novice Android developer how to display a View in an Activity that contains a vertically scrolling rainbow or spectrum of colours using a mapping from HSV (hue, saturation, value) model space to RGB (red, green, blue) colour space (the one your Android device directly uses.)

In this tutorial you will come across the following Android SDK objects:

. LinearLayout
. Activity
. View
. Canvas
. Paint
. ArrayList

Happy learning, and see you all soon in the next tutorial!
