这篇文章主要为大家详细解析了Android SwipeRefreshLayout下拉刷新源码,具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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);
}
}
