Android(安卓)UI开发第二十一篇――下拉刷新列表实现（pull to refresh）

android中提供了ListView控件，listview能够为我们展现丰富的内容，有时候我们为了提升用户体检，需要更炫而且更好用户体验的效果，pull to refresh（下拉刷新列表效果）就应运而生了。

pull to refresh更多的应用于获取最新的内容，比如新浪微博、腾讯微博等。目前网上有很多开源的pull to refresh的开源实现，这里也是参考开源代码实现的。

Layout

<!-- The PullToRefreshListView replaces a standard ListView widget. --> <com.markupartist.android.widget.PullToRefreshListView     android:id="@+id/android:list"     android:layout_height="fill_parent"     android:layout_width="fill_parent"     />

Activity

// Set a listener to be invoked when the list should be refreshed. ((PullToRefreshListView) getListView()).setOnRefreshListener(new OnRefreshListener() {     @Override     public void onRefresh() {         // Do work to refresh the list here.         new GetDataTask().execute();     } });  private class GetDataTask extends AsyncTask<Void, Void, String[]> {     ...     @Override     protected void onPostExecute(String[] result) {         mListItems.addFirst("Added after refresh...");         // Call onRefreshComplete when the list has been refreshed.         ((PullToRefreshListView) getListView()).onRefreshComplete();         super.onPostExecute(result);     } }
