Android : Adding a Fragment to Activity From an array adapter within a Fragment

I was brought onto a project that is using one activity and many fragments. On fragment has a listview that is using an arrayAdapter and each item from that listView is suppose to bring in a fragment over top of everything else upon click.

I am unclear how to access the fragmentManager of the given activity, from an array adapter in an already added fragment.

Can someone point me to an example of this type of inflation?
