  <p>Simply my RowsFragment is look like this,</p>
  
  <pre><code>public static class SampleFragmentB extends RowsFragment {
          private final ArrayObjectAdapter mRowsAdapter;
  
          public SampleFragmentB() {
              mRowsAdapter = new ArrayObjectAdapter(new ShadowRowPresenterSelector());
  
              setAdapter(mRowsAdapter);
              setOnItemViewClickedListener(new OnItemViewClickedListener() {
                  @Override
                  public void onItemClicked(
                          Presenter.ViewHolder itemViewHolder,
                          Object item,
                          RowPresenter.ViewHolder rowViewHolder,
                          Row row) {
                      Toast.makeText(getActivity(), "Implement click handler", Toast.LENGTH_SHORT)
                              .show();
                  }
              });
          }
  
          @Override
          public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              createRows();
              getMainFragmentAdapter().getFragmentHost().notifyDataReady(getMainFragmentAdapter());
          }
  
          private void createRows() {
                  String json = Utils.inputStreamToString(getResources().openRawResource(
                          R.raw.page_row_example));
                  CardRow[] rows = new Gson().fromJson(json, CardRow[].class);
                  for (CardRow row : rows) {
                      mRowsAdapter.add(createCardRow(row));
                  }
          }
  
          private Row createCardRow(CardRow cardRow) {
              PresenterSelector presenterSelector = new CardPresenterSelector(getActivity());
              ArrayObjectAdapter adapter = new ArrayObjectAdapter(presenterSelector);
              for (Card card : cardRow.getCards()) {
                  adapter.add(card);
              }
  
              HeaderItem headerItem = new HeaderItem(cardRow.getTitle());
              return new CardListRow(headerItem, adapter, cardRow);
          }
      }
  </code></pre>

  <p>So I want to make always visible Header of each row without selecting into or focusing into RowsFragment. I'am using leanback v24 to add multiple rows into each header item.</p>
