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：

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/swipe_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <!-- android:id="@id/android:list" 

    <ListView
        android:id="@+id/list11"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:choiceMode="singleChoice"
        android:descendantFocusability="blocksDescendants"
        android:divider="@null"
        android:scrollbars="none" >
    </ListView>-->

    <com.maomao.beautymovie.widget.CustomListView
        android:id="@+id/movielistview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:choiceMode="singleChoice"
        android:descendantFocusability="blocksDescendants"
        android:divider="@null"
        android:scrollbars="none" >
    </com.maomao.beautymovie.widget.CustomListView>

</android.support.v4.widget.SwipeRefreshLayout>

 

在activity或fragment中使用即可：

package com.maomao.beautymovie.fragment;


public class AllMovieFragment extends Fragment{

    private static final String TAG = "movieFragment";
    private SwipeRefreshLayout swipeLayout;
    private CustomListView movieListView;
    private MovieListAdapter movieListAdapter;
    private List<MovieBean> moviesLsit;
    
    public AllMovieFragment()
    {
    }

    public AllMovieFragment(List<MovieBean> moviesLsit)
    {
        this.moviesLsit = moviesLsit;
    }
    
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }

    @SuppressLint("InlinedApi")
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view            = inflater.inflate(R.layout.allmoviefrag, container, false);
        movieListView = (CustomListView)view.findViewById(R.id.movielistview);

        movieListAdapter = new MovieListAdapter(getActivity(), moviesLsit);
        
        movieListView.setAdapter(movieListAdapter); 
    
        initSwipeLayout(view);
    
        return view;
    }

    

    /**
     * 初始化SwipeRefreshLayout
     * @param view
     */
    public void initSwipeLayout(View view)
    {
        swipeLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_container);
        //swipeLayout.setOnRefreshListener(this);
        //swipeLayout.setOnLoadListener(this);
        swipeLayout.setColorScheme(android.R.color.holo_blue_bright,
                android.R.color.holo_green_light, android.R.color.holo_orange_light,
                android.R.color.holo_red_light);
      // 设置下拉刷新监听器
        swipeLayout.setOnRefreshListener(new OnRefreshListener() {

              @Override
              public void onRefresh() {

            Toast.makeText(getActivity(), "refresh", Toast.LENGTH_SHORT).show();

            swipeLayout.postDelayed(new Runnable() {

                @Override
                public void run() {
              // 更新数据
              //moviesLsit.addAll(MyDataSource.addMovieDataSource());
                    //最新出現的放在前面
              moviesLsit.addAll(0, MyDataSource.addMovieDataSource());
              movieListAdapter.notifyDataSetChanged();
              // 更新完后调用该方法结束刷新
              swipeLayout.setRefreshing(false);
                }
            }, 2000);
              }
          });
        
    
        
    }
    
    
}
