title: Searchview that filters a listview, with custom listview_items
body: <p>My app has got a custom ListView-Adapter that inflates a listview_item, which has multiple TextViews into a ListView.</p>
  
  <p>I have added a SearchView to the layout but I want have it so that it can search the ListView and filter it by looking if the data typed in the SearchView is the same as any of the data in the TextViews from the listview_items.</p>
