Set ParallaxHeader:

 ultimateRecyclerView.setParallaxHeader(getLayoutInflater().inflate(R.layout.parallax_recyclerview_header, ultimateRecyclerView.mRecyclerView, false));
        ultimateRecyclerView.setOnParallaxScroll(new UltimateRecyclerView.OnParallaxScroll() {
            @Override

                toolbar.setBackgroundDrawable(c);
            }
        });

Set swipe to refresh:

 ultimateRecyclerView.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                new Handler().postDelayed(new Runnable() {

                        simpleRecyclerViewAdapter.insert("Refresh things", 0);
                        ultimateRecyclerView.setRefreshing(false);
                        //   ultimateRecyclerView.scrollBy(0, -50);
                        linearLayoutManager.scrollToPosition(0);
                    }
                }, 1000);
            }

Set swipe to dismiss:

  ultimateRecyclerView.setSwipeToDismissCallback(new SwipeToDismissTouchListener.DismissCallbacks() {
            @Override
            public SwipeToDismissTouchListener.SwipeDirection dismissDirection(int position) {
                return SwipeToDismissTouchListener.SwipeDirection.BOTH;
            }
            @Override
            public void onDismiss(RecyclerView view, List<SwipeToDismissTouchListener.PendingDismissData> dismissData) {
                for (SwipeToDismissTouchListener.PendingDismissData data : dismissData) {
                    simpleRecyclerViewAdapter.remove(data.position);
                }
            }
            @Override
            public void onResetMotion() {
                isDrag = true;
            }
            @Override
            public void onTouchDown() {
                isDrag = false;
            }
        });

Drag and drop:

   dragDropTouchListener = new DragDropTouchListener(ultimateRecyclerView.mRecyclerView, this) {
           @Override
           protected void onItemSwitch(RecyclerView recyclerView, int from, int to) {
               simpleRecyclerViewAdapter.swapPositions(from, to);
               simpleRecyclerViewAdapter.clearSelection(from);
               simpleRecyclerViewAdapter.notifyItemChanged(to);
               if (actionMode != null) actionMode.finish();
               Logs.d("switch----");
           }
           @Override
           protected void onItemDrop(RecyclerView recyclerView, int position) {
               Logs.d("drop----");
               ultimateRecyclerView.enableSwipeRefresh(true);
           }
       };
       dragDropTouchListener.setCustomDragHighlight(getResources().getDrawable(R.drawable.custom_drag_frame));
       ultimateRecyclerView.mRecyclerView.addOnItemTouchListener(dragDropTouchListener);

Animations:

  ultimateRecyclerView.setItemAnimator(Type.values()[position].getAnimator());
  ultimateRecyclerView.getItemAnimator().setAddDuration(300);
  ultimateRecyclerView.getItemAnimator().setRemoveDuration(300);

Showing and hiding toolbar and floating button:

  ultimateRecyclerView.setScrollViewCallbacks(new ObservableScrollViewCallbacks() {
            @Override
            public void onScrollChanged(int scrollY, boolean firstScroll, boolean dragging) {           
             }
            @Override
            public void onDownMotionEvent() {
            }
            @Override
            public void onUpOrCancelMotionEvent(ObservableScrollState observableScrollState) {
                if (observableScrollState == ObservableScrollState.DOWN) {
                     ultimateRecyclerView.showToolbar(toolbar, ultimateRecyclerView,getScreenHeight());
                } else if (observableScrollState == ObservableScrollState.UP) {
                      ultimateRecyclerView.hideToolbar(toolbar,ultimateRecyclerView,getScreenHeight());
                } else if (observableScrollState == ObservableScrollState.STOP) {
                }
            }
        });        

Show empty view when the adapter is null:

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
...
app:recyclerviewEmptyView="@layout/empty_view"/>

Show custom FloatingView(Both menu and button are fine. It is easy to set click event on them) when the adapter is null:

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
...
 app:recyclerviewFloatingActionView="@layout/floating_view"/>

Set custom colorful style of pull to refresh:

 <com.marshalchen.ultimaterecyclerview.CustomUltimateRecyclerview
 .../>

Using CustomUltimateRecyclerview instead of UltimateRecyclerView ultimateRecyclerView.setCustomSwipeToRefresh();

Set scrollbars of RecyclerView by set attributes of UltimateRecyclerView in xml layout:

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
        app:recyclerviewScrollbars="vertical" />                

Note that set scrollbars of RecyclerView dynamically by code is NOT SUPPORTED refer to this
