ViewPager внутри BottomSheetDialogFragment

Я пытаюсь установить viewpager внутри BottomSheetDialogFragment, но всегда с тем же результатом:

java.lang.IllegalStateException: Фрагмент не имеет вида

setupDialog

Код:

@Override
public void setupDialog(Dialog dialog, int style) {
    Log.d(TAG, "setupDialog");
    super.setupDialog(dialog, style);

    View root = View.inflate(getContext(), R.layout.fragment_daily_detail, null);
    dialog.setContentView(root);
    CoordinatorLayout.LayoutParams layoutParams =
            (CoordinatorLayout.LayoutParams) ((View) root.getParent()).getLayoutParams();
    CoordinatorLayout.Behavior behavior = layoutParams.getBehavior();

    if (behavior != null && behavior instanceof BottomSheetBehavior) {
        bottomSheetBehavior = (BottomSheetBehavior) behavior;
        bottomSheetBehavior.setBottomSheetCallback(mBottomSheetBehaviorCallback);
        bottomSheetBehavior.setPeekHeight((int) getResources().getDimension(R.dimen.fragment_forgot_password_min_height));
        Log.d(TAG, "State: " + bottomSheetBehavior.getState());

        imageClose = root.findViewById(R.id.imageViewClose);
        textViewTitle = (TextView) root.findViewById(R.id.textViewTitle);
        peekLayout = root.findViewById(R.id.peekLayout);
        tabLayout = (TabLayout) root.findViewById(R.id.tabs);
        viewPager = (ViewPager) root.findViewById(R.id.viewPager);

        recyclerView = (RecyclerView) root.findViewById(R.id.recyclerView);

        timesheetDay = timesheetDayList.get(pageNumber);

        imageClose.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                bottomSheetBehavior.setState(BottomSheetBehavior.STATE_HIDDEN);
            }
        });
        textViewTitle.setText(timesheetDay.getDate());

        sectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());
        viewPager.setAdapter(sectionsPagerAdapter);
        tabLayout.setupWithViewPager(viewPager);
    }
}

FragmentPagerAdapter

Код:

public class SectionsPagerAdapter extends FragmentPagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        return PageFragment.getInstance(timesheetDayList.get(position));
    }

    @Override
    public int getCount() {
        return timesheetDayList.size();
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return timesheetDayList.get(position).getDate();
    }
}

Было бы очень полезно для меня, если кто-нибудь знает что-то об этой реализации.

Приветствия и благодарности заранее!

Я решил проблему раздувания представления в "onCreateView()". Во всяком случае, я настроил RecyclerView внутри ViewPager, и вертикальная прокрутка RecyclerView очень нестабильна, иногда работает, а иногда нет, поэтому я попробую сделать этот экран по-другому.

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    Log.d(TAG, "onCreateview");

    View root = inflater.inflate(R.layout.fragment_daily_detail, container);

    mImageClose = root.findViewById(R.id.imageViewClose);
    mTextViewTitle = (TextView) root.findViewById(R.id.textViewTitle);
    mPeekLayout = root.findViewById(R.id.peekLayout);
    mTabLayout = (TabLayout) root.findViewById(R.id.tabs);
    mViewPager = (ViewPager) root.findViewById(R.id.viewPager);

    mImageClose.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getDialog().dismiss();
        }
    });

    mTextViewTitle.setText("Daily detail");

    mSectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());
    mViewPager.setAdapter(mSectionsPagerAdapter);
    mTabLayout.setupWithViewPager(mViewPager);

    mViewPager.setCurrentItem(mPageNumber);

    mPeekLayout.getViewTreeObserver().addOnGlobalLayoutListener(
            new ViewTreeObserver.OnGlobalLayoutListener() {

                @Override
                public void onGlobalLayout() {

                    BottomSheetDialog dialog = (BottomSheetDialog) getDialog();

                    FrameLayout bottomSheet = (FrameLayout) dialog.findViewById(android.support.design.R.id.design_bottom_sheet);
                    mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);

                    // gets called after layout has been done but before display
                    // so we can get the height then hide the view
                    int height = mPeekLayout.getHeight();
                    Log.d(TAG, "Height: " + height);
                    mBottomSheetBehavior.setPeekHeight(height);
                    mBottomSheetBehavior.setBottomSheetCallback(mBottomSheetBehaviorCallback);
                }
            });

    return root;
}
