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>

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。
