PullRefreshScrollView的上拉加载和下拉加载

Demo中的PullRefreshScrollView只有刷新这个方法，并没有细分上拉和下拉，自己找了半天，终于找到了解决方法：

PullToRefreshScrollView mPullRefreshScrollView = (PullToRefreshScrollView) findViewById(R.id.pull_refresh_scrollview);        mPullRefreshScrollView.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener2()        {            @Override            public void onPullDownToRefresh(PullToRefreshBase refreshView)            {                Log.e("下拉", "下拉");            }            @Override            public void onPullUpToRefresh(PullToRefreshBase refreshView)            {                Log.e("上拉", "上拉");            }        });

用PullToRefreshBase.OnRefreshListener2这个可以重写上拉和下拉方法。在次记录上方便以后使用。
