Android: Passing Objects Between Fragments

Question

Before i start, i have look through question such as:

Passing data between fragments: screen overlap How to pass values between Fragments

as well as Android

Answer 1

I found a solution to my question, which i am sure not the correct way to do that...

So in RegisterActivity.java i add + modified the following lines (thx to @sturrockad):

public Registration getRegistrationData(){
    return this.regData;
}

public void onEmailRegistered(int position, Registration regData){
    this.regData = regData;
    viewPager.setCurrentItem(position, true);
}

Then in RegisterTwoFragments.java (or in the Fragment to which i want to receive the Object):

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_register_two, container, false);
    regData = ((RegisterActivity) getActivity()).getRegistrationData();
    ...
