Android Sliding Tabs - modifying sample project

I am trying to create a sliding tabs app like the one in the screenshot below although due to the lack of samples available, this one is the closest I could find for what I want to achieve.

I would be very grateful if anybody could help me with following:

1. Which Java code needs to be removed in order to safely get rid of the colour picker at the bottom + what codes needs to replace it so that I can use a hex colour of my choice for the Action bar, Indicator colour, Tab titles, Tab backgrounds and Tab separators.


2. Which code (Java and/or XML) needs to change so that I can use XML fragment files of my own rather than these 'cards'.

All help would be very much appreciated as there is literally no sample project out there that does what I want to achieve.

The link to the sample project that I intend to modify is below.
