大家可能有的没有swipeRefreshLayout这个类，简单说一下，这是v4包里面的，19.1版本的时候就有了，但是当时的样式还是几个横杠，大概在21.0后吧，已经是我这个demo这样了。。挺好看的。一个圆形进度条.所以大家在使用时，请先升级一下自己的v4包,另外大家可能android support library已经是19.1以上了，还是没有，大家要注意一下，上面的Android Support Repository。更新到最新版本

1,继承SwipeRefreshLayout，自定义一个view   VRefresh

2.创建一个activity--SwipeRefreshDemo,创建activity之前,创建一个xml布局,直接引用自定义控制

3,在activity里面进行设置-核心代码

 @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_swipe_refresh_layout_view);        initialize();        for (int i = 0; i < 2; i++) {            A a = new A();            a.setDescribe("----" + i);            bean.add(a);        }        //进度条颜色        swiperefreshlayou.setColorSchemeResources(android.R.color.holo_red_light,android.R.color.holo_green_light, android.R.color.holo_blue_bright, android.R.color.holo_orange_light);//      swiperefreshlayou.setProgressBackgroundColor(getResources().getColor(android.R.color.holo_red_light));        swiperefreshlayou.setSize(0);//0和1  圆形进度条两种不同效果 0刚开始有渲染效果        myAdapter = new MyAdapter(bean, this);//listview adapter        swiperefreshlayou.setView(this, lv);//设置嵌套的子view -listview        swiperefreshlayou.setMoreData(false);//设置是否还有数据可加载(一般根据服务器反回来决定)        lv.setAdapter(myAdapter);        swiperefreshlayou.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {            @Override            public void onRefresh() {                Message msg = mhandler.obtainMessage();                msg.what = REFRESH_COMPLETE;                mhandler.sendMessageDelayed(msg, 3000);//3秒后通知停止刷新            }        });        swiperefreshlayou.setOnLoadListener(new VRefresh.OnLoadListener() {            @Override            public void onLoadMore() {                Message msg = mhandler.obtainMessage();                msg.what = LOADMORE_COMPLETE;                mhandler.sendMessageDelayed(msg, 3000);//3秒后通知停止加载更多            }        });    }

  加载完成后去handle更新

private static final int REFRESH_COMPLETE = 0;//刷新完成标识    private static final int LOADMORE_COMPLETE = 1;//加载更多完成标识    Handler mhandler = new Handler() {        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            switch (msg.what) {                case LOADMORE_COMPLETE:                    for (int i = 0; i < 5; i++) {                        A a = new A();                        a.setDescribe("----" + i);                        bean.add(a);                    }                    myAdapter.notifyDataSetChanged();                    swiperefreshlayou.setMoreData(true);//设置还有数据可以加载                    swiperefreshlayou.setLoading(false);//停止加载更多                    break;                case REFRESH_COMPLETE:                    bean.clear();                    for (int i = 0; i < 5; i++) {                        A a = new A();                        a.setDescribe("----" + i);                        bean.add(a);                    }                    swiperefreshlayou.setMoreData(true);//设置还有数据可以加载                    myAdapter.notifyDataSetChanged();                    swiperefreshlayou.setRefreshing(false);//停止刷新                    break;            }        }    };
