Android - Custom adapter getview creation?

[SauronWatchesYou]

Hi all I’m learning about adapters in Android but I read that creating a custom adapter is better as it provides customization and easy to implement. I like to know how things work behind the scenes but I can’t find out much about the creation of my listview adapter. I’m just looking for how the getView is called, where the method parameters are getting passed in from, where from and what design pattern it is using, I think it’s the observer pattern?

CommonsWare has a nice excerpt about adapters. See here:
