//没少看鸿洋老师的视频，一如既往，鸿洋老师讲解的浅显易懂！
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：
[html]view plaincopy<RelativeLayoutxmlns:android="/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>
题主用的AndroidStudio 1.5,果然和知乎一样酷啊！！
2、MainActivty:
package com.example.ollydebug.swiperefreshlayoutpractice;import android.annotation.SuppressLint;import android.app.Activity;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.support.v4.widget.SwipeRefreshLayout;import android.widget.ArrayAdapter;import android.widget.ListView;import java.util.ArrayList;import java.util.Arrays;import java.util.List;public class MainActivity extends Activity implements SwipeRefreshLayout.OnRefreshListener {private static final int REFRESH_COMPLETE = 0X110;private SwipeRefreshLayout mrefreshLayout;private ListView mlistView;private ArrayAdapter<String>mAdapter;private List<String> mDatas = new ArrayList<String>(Arrays.asList("Java","PHP","Swift","JavaScript","C++","C#"));private Handler mHandler = new Handler(){@Overridepublic void handleMessage(Message msg) {switch (msg.what){case REFRESH_COMPLETE:mDatas.addAll(Arrays.asList("Mysql", "Ajax", "知乎", "掟上今日子的备忘录"));mAdapter.notifyDataSetChanged();mrefreshLayout.setRefreshing(false);break;}}};@SuppressLint("InlinedApi")protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mlistView = (ListView)findViewById(R.id.ListView);mrefreshLayout = (SwipeRefreshLayout)findViewById(R.id.id_swipe_ly);mrefreshLayout.setOnRefreshListener(this);mrefreshLayout.setColorSchemeColors(getResources().getColor(android.R.color.holo_blue_bright),getResources().getColor(android.R.color.holo_green_light),getResources().getColor(android.R.color.holo_orange_light),getResources().getColor(android.R.color.holo_red_light));mAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, mDatas);mlistView.setAdapter(mAdapter);}@Overridepublic void onRefresh() {mHandler.sendEmptyMessageAtTime(REFRESH_COMPLETE,1000);}}
好了，结束，我感觉效果挺好看的，不妨试试。

ok ~
但是博主我的是~~(果然和知乎一样!哈哈)
