Setting RadioButton.setChecked with Multiple Fragments

Question

Hey I have a really stupid problem and I can't figure out why it is not working as expected. So I have a MultiFragment layout (each one has some different questions) using viewpager and FragmentStatePagerAdapter. When I open the screen that hosts all these fragments I am trying to restore the previous state (marking all answered questions) using a network call. However it seems that if my Fragment is not visible to the user it can't update the checked state of the radio button / checkboxes.

Does anybody know what I can do to achieve the wished behavior?

Cheers and thanks in advance!

 @Override
 public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
     super.onViewCreated(view, savedInstanceState);
     presenter.restoreAnswersFromPreviousSession(questionId);
}

@Override 
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if (isVisible()) {
        if (isVisibleToUser) {
            presenter.restoreAnswersFromPreviousSession(questionId);
            Log.d("Fit", "My Fragment is visible");
        } else {
                   Log.d("Fit", "My Fragment is not visible");
               }
    }
}

Here I restore the state (called after the request is successful)

previousReplies = repliesToRestore;
for (QualityReportReply reportReply : repliesToRestore) {
  int id = reportReply.id();
  switch (id) {
    case 201: {
      boolean tooThin = (boolean) reportReply.value();
      if (tooThin) {
        materialTooThinGroupYes.setChecked(true);
      } else {
        materialTooThinGroupNo.setChecked(true);
      }
      break;
    }
    case 202: {
      boolean tooThick = (boolean) reportReply.value();
      if (tooThick) {
        materialTooThickGroupYes.setChecked(true);
      } else {
        materialTooThickGroupNo.setChecked(true);
      }
      break;
    }
    case 203: {
      boolean drawingThreads = (boolean) reportReply.value();
      if (drawingThreads) {
        materialDrawThreadsGroupYes.setChecked(true);
      } else {
        materialDrawThreadsGroupNo.setChecked(true);
      }
      break;
    }
    case 204: {
      boolean flyingThreads = (boolean) reportReply.value();
      if (flyingThreads) {
        materialFlyingThreadsGroupYes.setChecked(true);
      } else {
        materialFlyingThreadsGroupNo.setChecked(true);
      }
      break;
    }
    case 205: {
      boolean knots = (boolean) reportReply.value();
      if (knots) {
        materialKnotsGroupYes.setChecked(true);
      } else {
        materialKnotsGroupNo.setChecked(true);
      }
      break;
    }

UPDATE

Here is a working example, you can see it.

I think you are restoring state on the host Activity. Don't do this, do it in each Fragment. Let's say you have two fragments, Passform and Material, so instead of doing it in Activity, make a call inside fragment's onCreateView.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_passform, container, false);
    new FetchPassFormState().execute();
    return view;
}

Update views inside onPostExecute of FetchPassFormState or wherever you want, as per your need.

UPDATE

You can do one thing. You must be adding Fragments in your QuestionsViewPagerAdapter, try to setArguments of your Fragments there. Like,

Fragment fragment = new YourFragment();
Bundle bundle = new Bundle();
bundle.putString("your_key", "Your Data");
...
fragment.setArguments(bundle);

Now add this fragment. And inside Fragment's onCreateView, get this Bundle.

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_material_questions, container, false);
    ButterKnife.bind(this, view);
    getFragmentComponent().inject(this);
    presenter.setView(this);

    Bundle bundle = getArguments();
    String youdData = bundle.getString("your_key");
    ...
}

And then use this data to set views.
