title: Switch activities while already within a tab
body: <p>I have a swipeable tab layout in my android application, I wanted to make a switchable activity within my second tab (maybe using a toggle button) that would switch between a list view that's populated from a database and Google maps api which would dot the same data on the map using the longitude and latitude from the data in the database. </p>
  
  <p>Wondering if this is possible, bare in mind I already have the tabs on the top of the screen so to add a toggle button would have to be with the activity that's shown by default but when clicked would switch from the list view activity to the google maps api and switch back etc </p>
