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): 為布局添加一個Listener

setRefreshing(boolean): 顯示或隱藏刷新進(jìn)度條

isRefreshing(): 檢查是否處于刷新狀態(tài)

setColorScheme(): 設(shè)置進(jìn)度條的顏色主題，最多能設(shè)置四種

布局：在最外層加上SwipeRefreshLayout，他的child是可滾動的view即可，如ScrollView或者ListView

在代碼中使用：

public?class?MainActivity?extends?ActionBarActivity?{

	@Override
	protected?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);
			????????????}
		});
	}

	
}
