SwipeRefreshLayout在v4包下，对应的v4Demo中也有相应的例子。如果没有请下载最新support-v4

SwipeRefreshLayout 只能有一个直接子View，可能是一个ListView或一个Layout或其他需要刷新的组件。

setOnRefreshListener 用于监听刷新的动作。SwipeRefreshLayout 下拉，就会有刷新的效果出来，触发该监听。

如果需要一个刷新的动画，setRefreshing(true)， 停: setRefreshing(false)

如果要禁用刷新动画和手势响应，ssetEnable(false)，  恢复setEnable(true)

来个v4的例子：

public class SwipeRefreshLayoutActivity extends Activity implements OnRefreshListener {
    public static final String[] TITLES =
    {
            "Henry IV (1)",
            "Henry V",
            "Henry VIII",
            "Richard II",
            "Richard III",
            "Merchant of Venice",
            "Othello",
            "King Lear",
            "Henry IV (1)",
            "Henry V",
            "Henry VIII",
            "Richard II",
            "Richard III",
            "Merchant of Venice",
            "Othello",
            "King Lear",
            "Henry IV (1)",
            "Henry V",
            "Henry VIII",
            "Richard II",
            "Richard III",
