Regarding the Model-View-Controller approach, all you need to do is create a model with the data that matches your search and hand it tho the view (your list view) that will display it.

You probably want a setOnQueryTextListener which can filter your results when text is written in SearchView.

There is an existing post explaining this quite well, Implementing SearchView in action bar.
