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);
