Infinite Scrolling

So i'm that kind of developer that likes to rebuild frameworks, library's from scratch just for fun though. So i took up the task of building an infinite scroll feature like facebook, twitter apps etc. As I looked for resources online I saw some really complex code to do it. I never went with this approach though. What I did was create a list item with an array adapter an as the user scrolled to the bottom I included some code to check to see if the user had reached the bottom

If that was the case all I did was add more items to the listview and called notifyOnDataSetChanged (I think thats the name)

TO my surprise this worked with just a fraction of code of which I saw from the online resources. The code add new list items to the bottom of the list view while maintaining the position.

Now this baffles be at the same time, is my approach wrong am I not considering any other important factors? Because my code came up to about 10 lines compared to the resources.
