PullToRefreshListView类图

控制下拉刷新和上拉加载的显示和动画运动

PullToRefreshWebView

+ attribute1:type = defaultValue+ attribute2:type- attribute3:type

IPullToRefresh

LoadingLayout

ProgressBar mHeaderProgress;ImageView mHeaderImage;+TextView mHeaderText;

+ void reset()void onPullImpl(float var1)；void pullToRefreshImpl();void refreshingImpl();void releaseToRefreshImpl();void resetImpl();

FlipLoadingLayout

构建一个旋转加载动画

ILoadingLayout

void setLastUpdatedLabel(CharSequence var1); void setLoadingDrawable(Drawable var1); void setPullLabel(CharSequence var1); void setRefreshingLabel(CharSequence var1); void setReleaseLabel(CharSequence var1); void setTextTypeface(Typeface var1);

ProgressBar

系统类

FrameLayout

系统类，帧布局

InternalListViewSDK9

PullToRefreshListView

具体开始调用子类

ListView createRefreshableView()LoadingLayoutProxy createLoadingLayoutProxy

PullToRefreshBase

T mRefreshableView ; listView对象

PullToRefreshGridView

gridView子类

加载中控件，该类中只是进行了页面加载初始化等简单操作，具体业务都是调用抽象方法OnPullImpl()...

OverscrollHelper

根据滚动的位置更新刷新状态调用setState(）

PullToRefreshScrollView

PullToRefreshHorizontalScrollView

PullToRefreshAdapterViewBase

-OnScrollListener mOnScrollListener;//该类中的onScroll()会回到listener中的方法

-convertEmptyViewLayoutParams()+boolean getShowIndicator()+void onScroll()//父类中的ListView对象回调该方法+void onScrollStateChanged(）//父类中的ListView对象回调该方法+void setAdapter(ListAdapter adapter)给父类中的listView对象设置adapter+void setEmptyView(）+void onPullToRefresh()执行下拉动画和加载动画+void onRefreshing()滚动到指定位置，然后调用刷新完成回调+void onReleaseToRefresh()执行释放刷新动画

PullToRefreshExpandableListView

listview扩展类添加了空视图

帧动画loading实现了父类的开始和停止动画方法，并填充了动画类型

适配器类，给AbsListView子类使用

FrameAnimationLoadingLayout

- AnimationDrawable animationDrawable;

pullToRefreshImpl()void resetImpl()

OnScrollListener

滚动接口

LinearLayout

系统类线性布局

子类继承了该类，可以包含listView、gridView、scrollView、等子视图，给这些子视图添加刷新状态

InternalListView

-boolean mAddedLvFooter = false

+ void setEmptyView(View emptyView)
