上拉刷新方法

@Overridepublic void onRefresh() {    handler.postDelayed(new Runnable() {        @Override        public void run() {            i = i + 1;            getinfo("刷新");            load();        }    }, 2000);}

下拉加载的方法

@Overridepublic void onLoadMore() {    handler.postDelayed(new Runnable() {        @Override        public void run() {            i = i + 1;            getinfo("加载");            load();        }    }, 2000);}
