以下App基本都有下拉刷新的功能，曾经基本都使用XListView或者自己写一个下拉刷新，最近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已经使用这样的下拉刷新了）。

Google也在官方站点给出了V4的兼容包：

顺便看一眼API呗：

和XlistView差点儿相同，还是非常方便使用的，大概就这4个经常使用的方法，以下贴个简单的样例。

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>

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);

	}
}

效果图：
