Google终于出下拉刷新控件了，你们知道吗？ 2014年3月29日


XML文件需要引用android.support.v4.widget.SwipeRefreshLayout控件，在里面

可以放置任何一个控件，包括ListView，scrollview，gridview等

等，。都可以下拉刷新。。。。。。

main_activity.xml代码：
<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>
