RecycleView三种表现形式的上拉加载和下拉刷新

RecycleView可以表现成三种：
1、ListView
2、瀑布流
3、GridView

其实这三种控件现在都有各自的类以及对应的上拉和下拉，但是RecycleView出来后，一个控件就能将这3个控件表现出来，是在是强大，只要重新封装一下RecycleView就行了。

实现ListView的上拉下拉，请看效果

mRecyclerView = (PullRefreshRecyclerView) view.findViewById(R.id.recycle_list);
        mRecyclerView.setLinearLayout();
        mRecyclerView.setRefreshLoadMoreListener(this);
        mRecyclerView.setAdapter(new XXXXAdapter());

实现GridView的上拉下拉，请看效果

 mRecyclerView = (PullRefreshRecyclerView) view.findViewById(R.id.movie_recycle_list);
        //3列
        mRecyclerView.setGridLayout(3);
        mRecyclerView.setRefreshLoadMoreListener(this);
        mRecyclerView.setAdapter(new XXXXAdapter());

实现瀑布流的上拉下拉，请看效果

mRecyclerView = (PullRefreshRecyclerView) view.findViewById(R.id.pic_recyclerView);
mRecyclerView.setStaggeredGridLayout(2);
        mRecyclerView.setRefreshLoadMoreListener(this);
