ProfileFragment mProfileFragment = new ProfileFragment(); 
FragmentManager fragmentManager = getFragmentManager(); 
FragmentTransaction fragmentTransaction = fragmentManager 
.beginTransaction(); 
fragmentTransaction.replace(R.id.content_frame, 
mProfileFragment); 
fragmentTransaction.addToBackStack(MyProfileFragment.class 
.getName()); 
fragmentTransaction.commit();
