SwipeRefreshLayout嵌套ScrollView实现下拉刷新

API doc：http://developer.android.com/reference/android/support/v4/widget/SwipeRefreshLayout.html

首先须把你的support library的版本升级到19.1或更新

效果：

使用超级简单！

在layout中添加SwipeRefreshLayout

 <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/swipe_container"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >

     <ScrollView
         android:layout_width="match_parent"
         android:layout_height="wrap_content" >

         <TextView
             android:id="@+id/textView1"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:gravity="center"
             android:paddingTop="10dp"
             android:text="@string/swipe_to_refresh"
             android:textSize="20sp"
             android:textStyle="bold" />
     </ScrollView>

 </android.support.v4.widget.SwipeRefreshLayout>

在Activity中使用：

 tv = (TextView)findViewById(R.id.textView1);
         swipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.swipe_container);
         //设置刷新时动画的颜色，可以设置4个
         swipeRefreshLayout.setColorSchemeResources(android.R.color.holo_blue_light, android.R.color.holo_red_light, android.R.color.holo_orange_light, android.R.color.holo_green_light);
         swipeRefreshLayout.setOnRefreshListener(new OnRefreshListener() {

             @Override
             public void onRefresh() {
                 tv.setText("正在刷新");
                 // TODO Auto-generated method stub
                 new Handler().postDelayed(new Runnable() {

                     @Override
                     public void run() {
                         // TODO Auto-generated method stub
                         tv.setText("刷新完成");
                         swipeRefreshLayout.setRefreshing(false);
                     }
                 }, );
             }
         });

PS：setColorScheme()已经弃用，使用setColorSchemeResources()来设置颜色。
