首先在xml布局中声明swiperefresh控件，直接上代码：

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/swipeRefresh"
        android:orientation="vertical"
        tools:context="com.example.administrator.ordersystem.fragment.StayOperaterFragment">
    
        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent">
        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <android.support.v7.widget.Toolbar
                android:background="#309cfc"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">
    
                <TextView
                    android:id="@+id/title_number"
                    android:textSize="20dp"
                    android:textColor="#fff"
                    android:gravity="center"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:text="待操作"/>
            </android.support.v7.widget.Toolbar>
            <ListView
                android:id="@+id/operator_listview"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
    
            </ListView>
        </LinearLayout>
    
        </ScrollView>
    </android.support.v4.widget.SwipeRefreshLayout>

然后在fragment代码中：

public class StayOperaterFragment extends Fragment implements SwipeRefreshLayout.OnRefreshListener{
        private ListView listView;
        private List<ListInfoBean> list;
        private String  strNO,strName;
        private  ListInfoAdapter adapter;
        private TextView title_number;
        private SwipeRefreshLayout swipeRefresh;
    
        @Override
        public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.fragment_stay_operater, container, false);
            listView = (ListView) view.findViewById(R.id.operator_listview);
            title_number = (TextView) view.findViewById(R.id.title_number);
            swipeRefresh = (SwipeRefreshLayout) view.findViewById(R.id.swipeRefresh);
           
            init();
    
            //设置刷新出现的位置
            //
            swipeRefresh.setProgressViewEndTarget(false, 200);
    //绑定监听
           swipeRefresh.setOnRefreshListener(this);
    //设置颜色
     swipeRefresh.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);
            swipeRefresh.setDistanceToTriggerSync(50);
            
        @Override
        public void onRefresh() {
                      list.clear();
                         init();
     new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            swipeRefresh.setRefreshing(false);
                        }
                    },4000);
                }

基本就是这样的，就可以实现下拉刷新了，刷新数据可以在onRerfresh方法中
