Android PullToRefreshListView上拉刷新和下拉刷新-白红宇

　PullToRefreshListView实现上拉和下拉刷新有两个步骤：

　　1、设置刷新方式

pullToRefreshView.setMode(PullToRefreshBase.Mode.BOTH);//两端刷新     pullToRefreshView.setMode(PullToRefreshBase.Mode.PULL_FROM_START);//上拉刷新     pullToRefreshView.setMode(PullToRefreshBase.Mode.PULL_FROM_END);//下拉刷新

　　2、如果是上拉刷新或者下拉刷新需要实现OnRefreshListener接口；如果是两端刷新，则setOnRefreshListener需要实现OnRefreshListener2接口

　　两端刷新实现：

pullToRefreshView = (PullToRefreshListView) view.findViewById(R.id.pull_to_refresh_listview);        pullToRefreshView.setMode(PullToRefreshBase.Mode.BOTH);//两端刷新//        pullToRefreshView.setMode(PullToRefreshBase.Mode.PULL_FROM_START);//上拉刷新//        pullToRefreshView.setMode(PullToRefreshBase.Mode.PULL_FROM_END);//下拉刷新        pullToRefreshView.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener2
      
       () {            @Override            public void onPullDownToRefresh(PullToRefreshBase
       
         refreshView) {                refreshType = REFRESH_TYPE_DOWN;                refreshView.getLoadingLayoutProxy().setRefreshingLabel("正在加载");                refreshView.getLoadingLayoutProxy().setPullLabel("下拉加载更多");                refreshView.getLoadingLayoutProxy().setReleaseLabel("释放开始加载");//                refreshView.getLoadingLayoutProxy().setLastUpdatedLabel("最后加载时间:");                // Do work to refresh the list here.                new GetDataTask().execute();            }            @Override            public void onPullUpToRefresh(PullToRefreshBase
        
          refreshView) {                refreshType = REFRESH_TYPE_UP;                refreshView.getLoadingLayoutProxy().setRefreshingLabel("正在加载");                refreshView.getLoadingLayoutProxy().setPullLabel("上拉加载更多");                refreshView.getLoadingLayoutProxy().setReleaseLabel("释放开始加载");//                refreshView.getLoadingLayoutProxy().setLastUpdatedLabel("最后加载时间:");                // Do work to refresh the list here.                new GetDataTask().execute();            }        });

　　AsyncTask实现异步加载

private class GetDataTask extends AsyncTask
      
        {        @Override        protected String[] doInBackground(Void... params) {            try {                Thread.sleep(3000);            } catch (InterruptedException e) {                e.printStackTrace();            }            return new String[0];        }        @Override        protected void onPostExecute(String[] result) {            // Call onRefreshComplete when the list has been refreshed.            pullToRefreshView.onRefreshComplete();            if(REFRESH_TYPE_DOWN == refreshType){                Article article = new Article();                article.setTitle("下拉刷新添加title");                adapter.insert(article,0);//adapter是一个LinkedList            }else if(REFRESH_TYPE_UP == refreshType){                Article article = new Article();                article.setTitle("上拉刷新添加title");                adapter.add(article);            }            super.onPostExecute(result);        }    }

　　如果想实现更丰富的效果可修改布局文件参数，如：
