Google自己的下拉刷新组件SwipeRefreshLayout

这个下拉刷新组件挺漂亮的，但官方 SwipeRefreshLayout只提供下拉刷新功能，很多时候我们需要上拉刷新功能，所以下载v4源码修改 SwipeRefreshLayout，与之相关联的文件有两个分别是SwipeProgressBar，BakedBezierInterpolator把这三个文件拷贝到项目里面，修改一下包名就可以了。如何实现上拉刷新功能，可以网上查阅其他作者的文章，都有相应的实例介绍，例如：

1.安卓自带下拉刷新SwipeRefreshLayout添加上拉刷新功能

2.让Android Support V4中的SwipeRefreshLayout支持上拉加载更多（扩展一下这个组件以实现上拉下载的目的）

下拉刷新当然还可以用到一些第三方开源库，如PullToRefresh, ActionBar-PullToRefresh等，这边就简单记录一下官方SwipeRefreshLayout的使用。

API doc：http://developer.android.com/reference/android/support/v4/widget/SwipeRefreshLayout.html

效果如图(网上找的，感谢原作者^_^)：

在布局文件中添加：

 1 <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:id="@+id/swipe_container"
 4     android:layout_width="match_parent"
 5     android:layout_height="match_parent"
 6     tools:context=".MainActivity" >
 7 
 8     <!-- android:id="@id/android:list" 
 9 
10     <ListView
11         android:id="@+id/list11"
12         android:layout_width="match_parent"
13         android:layout_height="match_parent"
14         android:choiceMode="singleChoice"
15         android:descendantFocusability="blocksDescendants"
16         android:divider="@null"
17         android:scrollbars="none" >
18     </ListView>-->
19 
20     <com.maomao.beautymovie.widget.CustomListView
21         android:id="@+id/movielistview"
22         android:layout_width="match_parent"
23         android:layout_height="match_parent"
24         android:choiceMode="singleChoice"
25         android:descendantFocusability="blocksDescendants"
26         android:divider="@null"
27         android:scrollbars="none" >
28     </com.maomao.beautymovie.widget.CustomListView>
29 
30 </android.support.v4.widget.SwipeRefreshLayout>

在activity或fragment中使用即可：

 1 package com.maomao.beautymovie.fragment;
 2 
 3 
 4 public class AllMovieFragment extends Fragment{
 5 
 6     private static final String TAG = "movieFragment";
 7     private SwipeRefreshLayout swipeLayout;
 8     private CustomListView movieListView;
 9     private MovieListAdapter movieListAdapter;
10     private List<MovieBean> moviesLsit;
11     
12     public AllMovieFragment()
13     {
14     }
15 
16     public AllMovieFragment(List<MovieBean> moviesLsit)
17     {
18         this.moviesLsit = moviesLsit;
19     }
20     
21     
22     @Override
23     public void onCreate(Bundle savedInstanceState) {
24         super.onCreate(savedInstanceState);
25 
26     }
27 
28     @SuppressLint("InlinedApi")
29     @Override
30     public View onCreateView(LayoutInflater inflater, ViewGroup container,
31             Bundle savedInstanceState) {
32         View view            = inflater.inflate(R.layout.allmoviefrag, container, false);
33         movieListView = (CustomListView)view.findViewById(R.id.movielistview);
34 
35         movieListAdapter = new MovieListAdapter(getActivity(), moviesLsit);
36         
37         movieListView.setAdapter(movieListAdapter); 
38     
39         initSwipeLayout(view);
40     
41         return view;
42     }
43 
44     
45 
46     /**

49      */
50     public void initSwipeLayout(View view)
51     {
52         swipeLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_container);
53         //swipeLayout.setOnRefreshListener(this);
54         //swipeLayout.setOnLoadListener(this);
55         swipeLayout.setColorScheme(android.R.color.holo_blue_bright,
56                 android.R.color.holo_green_light, android.R.color.holo_orange_light,
57                 android.R.color.holo_red_light);
58       // 设置下拉刷新监听器
59         swipeLayout.setOnRefreshListener(new OnRefreshListener() {
60 
61               @Override
62               public void onRefresh() {
63 
64             Toast.makeText(getActivity(), "refresh", Toast.LENGTH_SHORT).show();
65 
66             swipeLayout.postDelayed(new Runnable() {
67 
68                 @Override
69                 public void run() {
70               // 更新数据
71               //moviesLsit.addAll(MyDataSource.addMovieDataSource());
72                     //最新出現的放在前面
73               moviesLsit.addAll(0, MyDataSource.addMovieDataSource());
74               movieListAdapter.notifyDataSetChanged();
75               // 更新完后调用该方法结束刷新
76               swipeLayout.setRefreshing(false);
77                 }
78             }, 2000);
79               }
80           });
81         
82     
83
