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

 package demo.veidy.com.veidydemolist;
import android.content.Context;
import android.support.v4.widget.SwipeRefreshLayout;
import android.support.v7.widget.RecyclerView;
import android.util.AttributeSet;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewConfiguration;
import android.widget.AbsListView;
import android.widget.ListView;/*** Created by veidy on 2015/1/16.*/
public class VRefresh extends SwipeRefreshLayout implements AbsListView.OnScrollListener {/*** 滑动到最下面时的上拉操作*/private int mTouchSlop;/*** listview实例*/private ListView mListView;/*** RecyclerView 实例*/private RecyclerView recyclerView;/*** 上拉监听器, 到了最底部的上拉加载操作*/private OnLoadListener mOnLoadListener;/*** ListView的加载中footer*/private View mFooterView;/*** 按下时的y坐标*/private int mYDown;/*** 抬起时的y坐标, 与mYDown一起用于滑动到底部时判断是上拉还是下拉*/
//    private int mLastY;/*** 是否在加载中 ( 上拉加载更多 )*/private boolean isLoading = false;private float mLastY = -1;/*** 最后一行*/boolean isLastRow = false;/*** 是否还有数据可以加载*/private boolean moreData = true;public VRefresh(Context context) {super(context);}public VRefresh(Context context, AttributeSet attrs) {super(context, attrs);mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();mFooterView = LayoutInflater.from(context).inflate(R.layout.vrefresh_footer, null, false);}/*** 设置默认的childview-必须要设置** @param context* @param childView*/public void setView(Context context, View childView) {if (childView instanceof ListView) {mListView = (ListView) childView;// 设置滚动监听器给ListView, 使得滚动的情况下也可以自动加载mListView.setOnScrollListener(this);mListView.setFooterDividersEnabled(false);Log.d("VRefresh", "获取到listview");} else if (childView instanceof RecyclerView) {recyclerView = (RecyclerView) childView;// 设置滚动监听器给ListView, 使得滚动的情况下也可以自动加载recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {@Overridepublic void onScrollStateChanged(RecyclerView recyclerView, int newState) {super.onScrollStateChanged(recyclerView, newState);}@Overridepublic void onScrolled(RecyclerView recyclerView, int dx, int dy) {super.onScrolled(recyclerView, dx, dy);Log.d("VRefresh", "dx=" + dx + "---dy=" + dy);}});Log.d("VRefresh", "获取到recyclerView");}initWithContext(context);}private void initWithContext(Context context) {if (mListView != null)mListView.addFooterView(mFooterView, null, false);//设置footview不可点击
//        if (recyclerView!=null){
//            Log.d("VRefresh","快去自定义recyclerView 加footview吧");
//            return;
//        }mFooterView.setVisibility(View.GONE);//默认先隐藏}@Overrideprotected void onLayout(boolean changed, int left, int top, int right, int bottom) {super.onLayout(changed, left, top, right, bottom);}/*** 是否可以加载更多, listview不在加载中, 且为上拉操作.** @param canload 是否还有可以加载的数据* @return*/private boolean canLoad(boolean canload) {return canload && !isLoading && isPullUp();}/*** 判断是否到了最底部*/private boolean isBottom() {if (mListView != null && mListView.getAdapter() != null) {return mListView.getLastVisiblePosition() == (mListView.getAdapter().getCount() - 1);}return false;}/*** 是否是上拉操作** @return*/private boolean isPullUp() {Log.d("VRefresh", "isPullUp--->");return (mYDown - mLastY) >= mTouchSlop;}/*** 如果到了最底部,而且是上拉操作.onLoadMore*/private void loadData() {Log.d("VRefresh", "loadData--->");if (mOnLoadListener != null) {// 设置状态setLoading(true);mOnLoadListener.onLoadMore();}}/*** @param loading*/public void setLoading(boolean loading) {isLoading = loading;if (isLoading) {
//            mListView.addFooterView(mFooterView);mFooterView.setVisibility(View.VISIBLE);} else {
//            mListView.removeFooterView(mFooterView);mFooterView.setVisibility(View.GONE);mYDown = 0;mLastY = 0;}}/** (non-Javadoc)* @see android.view.ViewGroup#dispatchTouchEvent(android.view.MotionEvent)*/@Overridepublic boolean dispatchTouchEvent(MotionEvent event) {final int action = event.getAction();if (mLastY == -1) {mLastY = (int) event.getRawY();}switch (action) {case MotionEvent.ACTION_DOWN:// 按下mYDown = (int) event.getRawY();Log.d("VRefresh", "按下");break;case MotionEvent.ACTION_MOVE:// 移动mLastY = (int) event.getRawY();final float deltaY = event.getRawY() - mLastY;Log.d("VRefresh", "移动");
//                if (null != mListView && isPullUp()) {
//                    if (mListView.getLastVisiblePosition() == mTotalItemCount - 1 || deltaY < 0) {
//                        mListView.setSelection(mTotalItemCount - 1);
//                    }
//                }break;default:
//                if (isLastRow && canLoad(moreData)) {
//                    Log.d("VRefresh", "能加载...");
//                    loadData();
//                } else {
//                    Log.d("VRefresh", "不能加载...");
//                }break;}return super.dispatchTouchEvent(event);}@Overridepublic void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {super.onMeasure(widthMeasureSpec, heightMeasureSpec);}/*** @param loadListener*/public void setOnLoadListener(OnLoadListener loadListener) {mOnLoadListener = loadListener;}@Overridepublic void onScrollStateChanged(AbsListView absListView, int i) {}@Overridepublic void onScroll(AbsListView absListView, int firstVisibleItem, int visibleItemCount, int totalItemCount) {//判断是否滚到最后一行if (firstVisibleItem + visibleItemCount == totalItemCount && totalItemCount > 0) {//双重判断，应该没有必要if (absListView.getLastVisiblePosition() == (absListView.getAdapter().getCount() - 1)) {isLastRow = true;
//                mFooterView.setVisibility(View.VISIBLE);if (canLoad(moreData)) {Log.d("VRefresh", "滚动到最后一行,加载数据，显示footview");loadData();}}Log.d("VRefresh", "滚动到最后一行");} else {Log.d("VRefresh", "没有滚动到最后一行");isLastRow = false;}}public static interface OnLoadListener {public void onLoadMore();}public boolean isMoreData() {return moreData;}public void setMoreData(boolean moreData) {this.moreData = moreData;}
}

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

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:paddingLeft="@dimen/activity_horizontal_margin"android:paddingRight="@dimen/activity_horizontal_margin"android:paddingTop="@dimen/activity_vertical_margin"android:paddingBottom="@dimen/activity_vertical_margin"><demo.veidy.com.veidydemolist.VRefreshandroid:id="@+id/swiperefreshlayou"android:layout_width="match_parent"android:layout_height="match_parent"><ListViewandroid:id="@+id/lv"android:layout_width="match_parent"android:layout_height="match_parent"></ListView></demo.veidy.com.veidydemolist.VRefresh>
</RelativeLayout>

3,在activity里面进行设置-核心代码

 @Overrideprotected 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 adapterswiperefreshlayou.setView(this, lv);//设置嵌套的子view -listviewswiperefreshlayou.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() {@Overridepublic 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() {@Overridepublic 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() {@Overridepublic 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;}}};
