Make a "pull up to get more" for a list on the Android

I just successfully used the Pull To Refresh by johannilsson in order to pull down a list to update it. Now I am trying to make basically the same concept to pull up a list from the bottom in order to trigger getting more items from the server (The server I am calling returns a limited amount 开发者_如何转开发of items each time). I thought it would be a simple inversion but after two days of trying to invert what the pull down does I am ready to pull out my hair. Has anyone ever done something like this that they could point me to?
