                String msg = "item[" + position + "]= " + parent.getItemIdAtPosition(position);

                Toast.makeText(context, msg, 1000).show();
                System.out.println(msg);

            }
        });

    }
}

in onCreateView of dummySectionFragment how to add different list view. I just able to work on visibility of view.

You should Add Fragments to your viewpager for different page for different Tabs.
