Since we are using OOP thus Views are Objects too...And so every time we inflate those view to List View ( creating the objects inside them from there corresponding xml file in case we are creating them fro a layout) we create many objects...In order to save memory we use View Holder and that's why they smooth the scroll of the list, we create the object just one time by inflating it and just by changing the variables that are changing in each item of the list and showing it to the user....
