本文实例为大家分享了SwipeRefreshLayout下拉刷新源码，供大家参考，具体内容如下

1.SwipeRefreshLayout是Google在support v4 19.1版本的library更新的一个下拉刷新组件，实现刷新效果更方便。

弊端:只有下拉

//设置刷新控件圈圈的颜色swipe_refresh_layout.setColorSchemeResources(android.R.color.holo_blue_light, android.R.color.holo_orange_light, android.R.color.holo_red_light, android.R.color.holo_green_light);//设置刷新控件背景色swipe_refresh_layout.setProgressBackgroundColorSchemeColor(getResources().getColor(android.R.color.white));//设置滑动距离swipe_refresh_layout.setDistanceToTriggerSync(100);//设置大小模式swipe_refresh_layout.setSize(SwipeRefreshLayout.DEFAULT);//设置下拉刷新控件状态隐藏swipe_refresh_layout.setRefreshing(false);　　

2.在xml文件中引用android.support.v4.widget.SwipeRefreshLayout控件，在里面可以放置任何一个控件，例如ListView，gridview等。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.v4.widget.SwipeRefreshLayout android:id="@+id/id_swipe_ly" android:layout_width="match_parent" android:layout_height="match_parent" > <ListView android:id="@+id/id_listview" android:layout_width="match_parent" android:layout_height="match_parent" > </ListView> </android.support.v4.widget.SwipeRefreshLayout> </RelativeLayout>

3.Java代码

public class MainActivity extends Activity implements SwipeRefreshLayout.OnRefreshListener { private SwipeRefreshLayout swipeLayout; private ListView listView; private ListViewAdapter adapter; private List<ItemInfo> infoList; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); swipeLayout = (SwipeRefreshLayout) this.findViewById(R.id.swipe_refresh); swipeLayout.setOnRefreshListener(this); // 顶部刷新的样式 swipeLayout.setColorScheme(android.R.color.holo_red_light, android.R.color.holo_green_light, android.R.color.holo_blue_bright, android.R.color.holo_orange_light); infoList = new ArrayList<ItemInfo>(); ItemInfo info = new ItemInfo(); info.setName("coin"); infoList.add(info); listView = (ListView) this.findViewById(R.id.listview); adapter = new ListViewAdapter(this, infoList); listView.setAdapter(adapter); } public void onRefresh() { new Handler().postDelayed(new Runnable() { public void run() { swipeLayout.setRefreshing(false); ItemInfo info = new ItemInfo(); info.setName("coin-refresh"); infoList.add(info); adapter.notifyDataSetChanged(); } }, 500); }}
