How to Call Same Activity From Intent?

Answer 1

Intent i = new Intent(getActivity, YourActivity.class);
i.startActivity();

Or you can simply use:

getActivity().recreate();

Answer 2

You can call same fragment from itself as follows.

PlaceholderFragment newFragment = new PlaceholderFragment();

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.layoutContainer, newFragment , "New Fragment");
fragmentTransaction.addToBackStack("New Fragment");
fragmentTransaction.commit();
