    mObservableScrollView = (ObservableScrollView) rootView
				.findViewById(R.id.scroll_view);
    mStickyView = rootView.findViewById(R.id.sticky);
    mPlaceholderView = rootView.findViewById(R.id.placeholder);

    mCallbacks = new StickyScrollViewCallbacks(mStickyView,
				mPlaceholderView, mObservableScrollView);

    mObservableScrollView.setCallbacks(mCallbacks);

    mObservableScrollView.getViewTreeObserver().addOnGlobalLayoutListener(
				new StickyScrollViewGlobalLayoutListener(mStickyView,
						mPlaceholderView, mObservableScrollView, mCallbacks));

QuickReturnScrollView

    mObservableScrollView = (ObservableScrollView) rootView
				.findViewById(R.id.scroll_view);
    mStickyView = rootView.findViewById(R.id.sticky);
    mPlaceholderView = rootView.findViewById(R.id.placeholder);

    mCallbacks = new QuickReturnScrollViewCallbacks(mStickyView,
				mPlaceholderView, mObservableScrollView);

    mObservableScrollView.setCallbacks(mCallbacks);

    mObservableScrollView.getViewTreeObserver().addOnGlobalLayoutListener(
				new QuickReturnScrollViewGlobalLayoutListener(mStickyView,
						mPlaceholderView, mObservableScrollView, mCallbacks));

ListView

Layout

    <net.appkraft.scrollviewtricks.ObservableListView
        android:id="@+id/scroll_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <EditText android:id="@+id/sticky"  
        android:layout_width="match_parent" android:background="#ffffff"
        android:layout_height="48dp" />

Activity

StickScrollView

    mObservableListView = (ObservableListView) rootView
  			.findViewById(R.id.scroll_view);
    mStickyView = rootView.findViewById(R.id.sticky);
    mPlaceholderView = new View(getActivity());
    
    ...
    
    mCallbacks = new StickyListViewCallbacks(mStickyView,
  			mPlaceholderView, mObservableListView);

    mObservableListView.setCallbacks(mCallbacks);
    mObservableListView.addHeaderView(mPlaceholderView);
    
    mObservableListView.getViewTreeObserver().addOnGlobalLayoutListener(
				new StickyListViewGlobalLayoutListener(mStickyView,
						mPlaceholderView, mObservableListView, mCallbacks));

QuickReturnScrollView

    mObservableScrollView = (ObservableScrollView) rootView
				.findViewById(R.id.scroll_view);
    mStickyView = rootView.findViewById(R.id.sticky);
    mPlaceholderView = new View(getActivity());
    
    ...

    mCallbacks = new QuickReturnListViewCallbacks(mStickyView,
				mPlaceholderView, mObservableListView);

    mObservableScrollView.setCallbacks(mCallbacks);
    mObservableListView.addHeaderView(mPlaceholderView);

    mObservableListView.getViewTreeObserver().addOnGlobalLayoutListener(
				new QuickReturnListViewGlobalLayoutListener(mStickyView,
						mPlaceholderView, mObservableListView, mCallbacks));
