Android SwipeRefreshLayout 官方下拉刷新控件介绍

转载：http://blog.csdn.net/lmj623565791/article/details/24521483

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="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>

2、MainActivty:

 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 Thread

         mHandler.sendEmptyMessageDelayed(REFRESH_COMPLETE, 2000);

     }
 }

好了，结束，我感觉效果挺好看的，不妨试试。
