SwipeRefreshLayout实现下拉刷新

新建布局文件list_refresh.xml

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/fram_list"android:layout_height="match_parent"android:layout_width="match_parent"xmlns:tools="http://schemas.android.com/tools"//将布局文件和java文件绑定在一起tools:context="com.example.doubandemo.ListRefresh"><ListView    android:id="@+id/list_item"    android:layout_width="wrap_content"    android:layout_height="wrap_content"></ListView></android.support.v4.widget.SwipeRefreshLayout>

新建ListRefreshFragment类继承Fragment类实现SwipeRefreshLayout.OnRefreshListener接口，重写onRefresh()方法

public void onRefresh() {    mSwipeRefreshLayout.setRefreshing(true);    new Handler().postDelayed(new Runnable() {        public void run() {            mSwipeRefreshLayout.setRefreshing(false);        }    }, 3000);}

然后在onCreateView()中加载布局

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {    //加载布局文件    View view = inflater.inflate(R.layout.list_refresh,container,false);    //初始化数据    initData();    mSwipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.fram_list);    //为下拉刷新的滚动条设置颜色，可以设置4种    mSwipeRefreshLayout.setColorSchemeResources(            android.R.color.holo_blue_bright,            android.R.color.holo_green_light,            android.R.color.holo_orange_light,            android.R.color.holo_red_light    );    //因为实现了OnRefreshListener接口，所以这里可以传入this    mSwipeRefreshLayout.setOnRefreshListener(this);    ListView listView = (ListView) view.findViewById(R.id.list_item);    //填充ListView    listView.setAdapter(new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,listData));    return view;}

在MainActivity中加载Fragment
