public class QuickReturnHeaderListFragment3 extends ListFragment {

    // region Member Variables
    private String[] mValues;

    @InjectView(android.R.id.list) ListView mListView;
    @InjectView(R.id.quick_return_tv) TextView mQuickReturnTextView;
    // endregion

    // region Constructors
    public static QuickReturnHeaderListFragment3 newInstance() {
        QuickReturnHeaderListFragment3 fragment = new QuickReturnHeaderListFragment3();
        Bundle args = new Bundle();
        fragment.setArguments(args);
        return fragment;
    }

    public QuickReturnHeaderListFragment3() {
    }
    // endregion

    // region Lifecycle Methods
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_list_quick_return_header, container, false);
        ButterKnife.inject(this, view);
        return view;
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        mValues = getResources().getStringArray(R.array.countries);

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
                R.layout.list_item, R.id.item_tv, mValues);

        mListView.setAdapter(adapter);

        // Set up the QuickReturn scroll listener
        int headerHeight = getActivity().getResources().getDimensionPixelSize(R.dimen.header_height2);
        QuickReturnListViewOnScrollListener scrollListener = new QuickReturnListViewOnScrollListener(QuickReturnType.HEADER,
                mQuickReturnTextView, -headerHeight, null, 0);
        // Setting to true will slide the header and/or footer into view or slide out of view based 
        // on what is visible in the idle scroll state
        scrollListener.setCanSlideInIdleScrollState(true);
        mListView.setOnScrollListener(scrollListener);
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        ButterKnife.reset(this);
    }
    // endregion
}
