You can access activity elements and methods from fragment this way:

Activity template

public class ActivityMain extends AppCompatActivity {

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_content)
   }

   public void updateView(){
       // update your views & vars here
   }
}

Fragment template

public class BlankFragment extends Fragment {

   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {        
       return inflater.inflate(R.layout.fragment_blank, container, false);
   }
}

public void updateActivityView(){
    if (getActivity() != null){
        ((ActivityMain) getActivity()).updateView();
    }
}

For vice versa you can access fragment items from activity this way:

ExampleFragment fragment = (ExampleFragment) getFragmentManager().findFragmentById(R.id.example_fragment); 
fragment.specific_function_name();

Where R.id.example_fragment is most likely the FrameLayout id inside your xml layout
