title: Start a ListFragment from Activity
body: <p>I am developing an app to present a map (using a fragment) and a list (using a ListFragment). So, I have an activity that starts the application as well as the mapfragment or the list fragment, according to the the user's preferences. I can easily replace the current activity for the mapfragment with FragmentManager and FragmentTransaction. The problem that I have is how I can call or start the ListFragment from the activity. 
  The listfragment uses a ListViewAdapter class to inflate a customized layout (repetedly with different information) so if i want to use transaction, it will be necessary to use a listview container in the layout. The problem is that I am using a layout for the items and not a container.</p>
  
  <p>Any ideas to solve this problem or any other way to deal with starting a presenting the listfragment in the activity?</p>
