SwipeRefreshLayout
public class SwipeRefreshLayout
extends ViewGroup implements NestedScrollingParent, NestedScrollingChild

java.lang.Object
↳ android.view.View
↳ android.view.ViewGroup

↳android.support.v4.widget.SwipeRefreshLayout

API doc：http://developer.android.com/reference/android/support/v4/widget/SwipeRefreshLayout.html

主要方法

setOnRefreshListener(OnRefreshListener): 为布局添加一个Listener
setRefreshing(boolean): 显示或隐藏刷新进度条
isRefreshing(): 检查是否处于刷新状态
setColorScheme(): 设置进度条的颜色主题，最多能设置四种

布局：在最外层加上SwipeRefreshLayout，他的child是可滚动的view即可，如ScrollView或者ListView

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"android:id="@+id/swipe_refresh_layout">    <ScrollView        android:layout_width="match_parent"        android:layout_height="wrap_content">    <TextView        android:id="@+id/refresh"        android:layout_width="wrap_content"        android:layout_height="wrap_content"         android:layout_gravity="center"        android:textSize="24sp"        android:text="下拉刷新" />    </ScrollView></android.support.v4.widget.SwipeRefreshLayout>

在代码中使用：

public class MainActivity extends ActionBarActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);//requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);final TextView mTextView = (TextView)findViewById(R.id.refresh);final SwipeRefreshLayout mSwipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.swipe_refresh_layout);mSwipeRefreshLayout.setColorSchemeResources(android.R.color.holo_blue_bright, android.R.color.holo_blue_light, android.R.color.holo_green_light, android.R.color.holo_orange_light);mSwipeRefreshLayout.setOnRefreshListener(new OnRefreshListener(){@Override               public void onRefresh() {  mTextView.setText("正在刷新");                 // TODO Auto-generated method stub  //boolean android.os.Handler.postDelayed(Runnable r, long delayMillis)                  new Handler().postDelayed(new Runnable() {                                          @Override                    public void run() {                         // TODO Auto-generated method stub                     mTextView.setText("刷新完成");                     mSwipeRefreshLayout.setRefreshing(false);                     }                 }, 5000);            }});}}
