在布局里添加即可：
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 9 <com.maomao.beautymovie.widget.CustomListView 10 android:id="@+id/movielistview" 11 android:layout_width="match_parent" 12 android:layout_height="match_parent" 13 android:choiceMode="singleChoice" 14 android:descendantFocusability="blocksDescendants" 15 android:divider="@null" 16 android:scrollbars="none" > 17 </com.maomao.beautymovie.widget.CustomListView> 18 19 </android.support.v4.widget.SwipeRefreshLayout>
在activity或fragment使用：
1 package com.maomao.beautymovie.fragment; 2 3 public class AllMovieFragment extends Fragment{ 4 5 private static final String TAG = "movieFragment"; 6 private SwipeRefreshLayout swipeLayout; 7 private CustomListView movieListView; 8 private MovieListAdapter movieListAdapter; 9 private List<MovieBean> moviesLsit; 10 11 public AllMovieFragment() 12 { 13 } 14 15 public AllMovieFragment(List<MovieBean> moviesLsit) 16 { 17 this.moviesLsit = moviesLsit; 18 } 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 initListView(); 39 40 41 42 return view; 43 } 44 45 46 47 public void initListView() 48 { 49 movieListView.setOnItemClickListener(new OnItemClickListener() { 50 51 52 @Override 53 public void onItemClick(AdapterView<?> parent, View view, int position, 54 long id) { 55 // 此处传回来的position和mAdapter.getItemId()获取的一致; 56 //parent.getAdapter().getItem(position) 57 MovieBean movieBean = (MovieBean)parent.getAdapter().getItem(position); 58 Toast.makeText(getActivity(), movieBean.getMovieName(), Toast.LENGTH_SHORT).show(); 59 //Toast.makeText(getActivity(), "位置"+Integer.toString(position), Toast.LENGTH_SHORT).show(); 60 61 } 62 }); 63 64 65 movieListView.setOnLoadListener(new OnLoadMoreListener() { 66 67 @Override 68 public void onLoadMore() { 69 // TODO 加载更多 70 Log.e(TAG, "onLoad"); 71 Toast.makeText(getActivity(), "load", Toast.LENGTH_SHORT).show(); 72 73 movieListView.postDelayed(new Runnable() { 74 75 @Override 76 public void run() { 77 moviesLsit.addAll(MyDataSource.addMovieDataSource()); 78 movieListAdapter.notifyDataSetChanged(); 79 // 加载完后调用该方法 80 movieListView.onLoadMoreComplete(); //加载更多完成 81 } 82 }, 5000); 83 84 85 } 86 }); 87 88 89 //CustomListView简单易用，如下代码即可说明，可选择性的开关下拉刷新和加载更多，同时可在设置界面设置是否启动自动加载更多 90 //关闭下拉刷新 91 movieListView.setCanRefresh(false); 92 //启动加载更多 93 movieListView.setCanLoadMore(true); 94 //启动自动加载更多 95 movieListView.setAutoLoadMore(false); 96 97 } 98 99 }
