SwipeRefreshLayout是V4包下提供的，使用时需要把要刷新的控件包裹起来。 <android.support.v4.widget.SwipeRefreshLayout android:id="@+id/swipRefreshLayout" android:layout_width="match_parent" android:layout_height="match_parent" > <ListView android:id="@+id/listview" android:layout_width="match_parent" android:layout_height="match_parent" > </ListView> </android.support.v4.widget.SwipeRefreshLayout>
