TwerkyListView

A beautiful RecyclerView which list items and animates similar to the peristaltic motion(twerking) of earthworms in Africa.(Inspiration for this project wasn't completely drawn imagining or studying how earthworms move neither does the author eat or rear earthworms hence any decision made by the reader to google twerking-African earthworms is at the sole discretion of the reader). also an IllegalTwerkingException() is thrown if Adapter does not extend TwerkyListView$TwerkAdapter

Method Summary

Method	Return	What it does
setTwerkInterpolators(Interpolator twerkpoleStart,Interpolator twerkpoleEnd)	void	decides twerking start and end motion interpolation
setTwerking(boolean twerking)	void	enables/cancels twerking
setTwerkingOffTime(int twerkOfftime)	void	resets the time it takes to complete twerk

by default(if setTwerkInterpolators(...) is never called)

• twerkpoleStart = new FastOutSlowInInterpolator();
• twerkpoleEnd = new OvershootInterpolator();
