页面向下滑动刷新

footerView = LayoutInflater.from(this.getActivity()).inflate(R.layout.listviewfooter, null);         //添加View到listView的footerView         listView.addFooterView(footerView);         //监听listView滑到到最底部         listView.setOnScrollListener(new OnScrollListener() {             //滑动状态改变的时候执行  滑到到停止  停止到滑动             @Override             public void onScrollStateChanged(AbsListView view, int scrollState) {                 if(scrollState == OnScrollListener.SCROLL_STATE_IDLE){//停止滑动的时候                     if(view.getLastVisiblePosition() == view.getCount() -1){//滑动到最底部  view.getLastVisiblePosition()  当前显示的最后一个Viewitem                         //滑到到底部的时候   调用加载数据的方法                         LoadNetWorkData();                     }                 }             }             //滑到的时候执行             @Override             public void onScroll(AbsListView view, int firstVisibleItem,                     int visibleItemCount, int totalItemCount) {             }         });

第二部刷新适配器

public void addData(List<CookBook> cookBooks){         this.cookBooks.clear();         this.cookBooks = cookBooks;         this.notifyDataSetChanged();//刷新适配器     }
