Show fragment recyclerViews in Parent Activity

Question

I am simply trying to show a fragments recyclerView inside it's parent activity. The data is there but nothing is showing up. Any thoughts? Here is PagerAdapter, parent and fragment classes with xmls so that all the parts are available to see. I want the RV to fit right here between the CardView and comment line. Thanks for any help!

PagerAdapter

public class DropPagerAdapter extends FragmentPagerAdapter{

final int PAGE_COUNT = 2;
private String tabTitles[] = new String[] { "Comments", "Riples"};
private Context context;

public DropPagerAdapter(FragmentManager fm, Context context) {
    super(fm);
    this.context = context;
}

@Override
public int getCount() {
    return PAGE_COUNT;
}

@Override
public Fragment getItem(int position) {
    return CommentFragment.newInstance(position + 1);
}

@Override
public CharSequence getPageTitle(int position) {
    // Generate title based on item position
    return tabTitles[position];
}
}

Fragment.java

public class CommentFragment extends Fragment {

public static final String ARG_PAGE = "ARG_PAGE";

private int mPage;
private String mDropObjectId;
private String mAuthorId;
private String mAuthorRank;
private String mAuthorName;
private String mAuthorFacebookId;
private String mDropDescription;
private String mRipleCount;
private String mCommentCount;
private Date mCreatedAt;
private String mTabName;
private RecyclerView mRecyclerView;
private TextView mViewDropEmptyView;
private ArrayList<CommentItem> mCommentList;
private CommentAdapter mCommentAdapter;

public static CommentFragment newInstance(int page) {
    Bundle args = new Bundle();
    args.putInt(ARG_PAGE, page);
    CommentFragment fragment = new CommentFragment();
    fragment.setArguments(args);
    return fragment;
}

@Override

    mRecyclerView = (RecyclerView) view.findViewById(R.id.comment_recycler_view);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

    mViewDropEmptyView = (TextView) view.findViewById(R.id.comment_empty_view);

    Intent intent = getActivity().getIntent();

Give some height to viewpager. I think relative layout won't support layout_weight property. Give some height and check once. — Harish_N, Jan 02 '16 at 04:19
@Harish_N You were exactly right. Submit as answer so I can upvote. Thanks! — Kevin Hodges, Jan 05 '16 at 01:19
@Harish_N This works in v-21, however, in pre lollipop the Slidertab is not showing up at all. Any idea why that would be? — Kevin Hodges, Jan 05 '16 at 01:33
Try to use SlidingTabLayout instead of TabLayout. http://stackoverflow.com/questions/26803835/slidingtablayout-to-fit-the-screen — Harish_N, Jan 05 '16 at 04:14
