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>

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。
