介绍：

UltimateRecyclerView 是一个实现了滑动刷新，上拉加载，滑动删除，拖动排序，滚动显示与隐藏toolbar等效果的RecyclerView控件。

运行效果：

使用说明：

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"

加载更多

 ultimateRecyclerView.enableLoadmore();

设置ParallaxHeader

 ultimateRecyclerView.setParallaxHeader(getLayoutInflater().inflate(R.layout.parallax_recyclerview_header, ultimateRecyclerView.mRecyclerView, false));
        ultimateRecyclerView.setOnParallaxScroll(new UltimateRecyclerView.OnParallaxScroll() {
            @Override
            public void onParallaxScroll(float percentage, float offset, View parallax) {
                Drawable c = toolbar.getBackground();
                c.setAlpha(Math.round(127 + percentage * 128));
                toolbar.setBackgroundDrawable(c);
            }
        });

设置滑动刷新

 ultimateRecyclerView.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        simpleRecyclerViewAdapter.insert("Refresh things", 0);
                        ultimateRecyclerView.setRefreshing(false);
                        //   ultimateRecyclerView.scrollBy(0, -50);
                        linearLayoutManager.scrollToPosition(0);
                    }
                }, 1000);
            }
        });

滑动删除

  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;
            }
        });

拖动排序

    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);

动画效果

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

toolbar与浮动操作按钮的显示与隐藏

  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) {
                }
            }
        });
