Google終於出下拉刷新控件了，你們知道嗎？ 2014年3月29日
XML文件需要引用android.support.v4.widget.SwipeRefreshLayout控件，在裏面
可以放置任何一個控件，包括ListView，scrollview，gridview等
等，。都可以下拉刷新。。。。。。
main_activity.xml代碼：
<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" >
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
</android.support.v4.widget.SwipeRefreshLayout>
