QR codes don't have a history on their own. If you are talking about building an app that scans QR codes, and you want to have a part of the app that shows the codes you've scanned in the past, you should write the scanned codes out to a database (SQLite is a good choice, but even a simple JSON file is pretty straightforward) and then display them in a listview. There are a number of samples that show you how to display data from a database in a listview.

This is painful.
Are you collecting these QR codes or are they are coming from a database somewhere?
Have you already written the QR part?
What have you done so far, what methodology have you used to store them and where are you stuck?
Please write more of those useful things... ermm what are they called... oh yes... Words!
