下面App基本都有下拉刷新的功能，以前基本都使用XListView或者自己写一个下拉刷新，近期Google提供了一个官方的下拉刷新控件SwipeRefreshLayout，我感觉还不错啊，见惯了传统的下拉刷新，这个反而给人耳目一新的感觉（貌似知乎的APP已经使用这种下拉刷新了）。
Google也在官方网站给出了V4的兼容包：
顺便看一眼API呗：
和XlistView差不多，还是很方便使用的，大概就这4个常用的方法，下面贴个简单的例子。
1、布局文件：
<RelativeLayout xmlns:android="/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent" ><android.support.v4.widget.SwipeRefreshLayoutandroid:id="@+id/id_swipe_ly"android:layout_width="match_parent"android:layout_height="match_parent" ><ListViewandroid:id="@+id/id_listview"android:layout_width="match_parent"android:layout_height="match_parent" ></ListView></android.support.v4.widget.SwipeRefreshLayout></RelativeLayout>
2、MainActivty:
/** Created by Storm Zhang, Mar 31, .*/package com.zhy.swiperefreshlayoutdemo;import java.util.ArrayList;import java.util.Arrays;import java.util.List;import android.annotation.SuppressLint;import android.app.Activity;import android.os.Bundle;import android.os.Handler;import android.support.v4.widget.SwipeRefreshLayout;import android.util.Log;import android.widget.ArrayAdapter;import android.widget.ListView;public class MainActivity extends Activity implements SwipeRefreshLayout.OnRefreshListener{private static final int REFRESH_COMPLETE = 0X110;private SwipeRefreshLayout mSwipeLayout;private ListView mListView;private ArrayAdapter<String> mAdapter;private List<String> mDatas = new ArrayList<String>(Arrays.asList("Java", "Javascript", "C++", "Ruby", "Json","HTML"));private Handler mHandler = new Handler(){public void handleMessage(android.os.Message msg){switch (msg.what){case REFRESH_COMPLETE:mDatas.addAll(Arrays.asList("Lucene", "Canvas", "Bitmap"));mAdapter.notifyDataSetChanged();mSwipeLayout.setRefreshing(false);break;}};};@SuppressLint("InlinedApi")protected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mListView = (ListView) findViewById(R.id.id_listview);mSwipeLayout = (SwipeRefreshLayout) findViewById(R.id.id_swipe_ly);mSwipeLayout.setOnRefreshListener(this);mSwipeLayout.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);mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mDatas);mListView.setAdapter(mAdapter);}public void onRefresh(){// Log.e("xxx", Thread.currentThread().getName());// UI ThreadmHandler.sendEmptyMessageDelayed(REFRESH_COMPLETE, 2000);}}
好了，结束，我感觉效果挺好看的，不妨试试。
