<!-- 
常用的一些属性:

ptr:ptrMode="both"  设置上拉和下拉都支持。
	可选值为:disabled(禁用下拉刷新), pullFromStart(仅支持下拉刷新), pullFromEnd(仅支持上拉刷新), both(二者都支持), manualOnly(只允许手动触发)
	也可以使用代码设置,在onCreate里面写:mPullRefreshListView.setMode(Mode.BOTH);//设置你需要的模式
	
设置图标 	ptr:ptrDrawable="@drawable/ic_launcher"

设置动画 	ptr:ptrAnimationStyle="flip" 倒置、ptr:ptrAnimationStyle="rotate"旋转

ptrRefreshableViewBackground 设置整个mPullRefreshListView的背景色

ptrHeaderBackground 设置下拉Header或者上拉Footer的背景色

ptrHeaderTextColor 用于设置Header与Footer中文本的颜色

ptrHeaderSubTextColor 用于设置Header与Footer中上次刷新时间的颜色

ptrShowIndicator 如果为true会在mPullRefreshListView中出现icon,右上角和右下角,挺有意思的。

ptrHeaderTextAppearance , ptrSubHeaderTextAppearance分别设置拉Header或者上拉Footer中字体的类型颜色等等。

ptrRotateDrawableWhilePulling 当动画设置为rotate时,下拉是是否旋转。

ptrScrollingWhileRefreshingEnabled 刷新的时候,是否允许ListView或GridView滚动。觉得为true比较好。

ptrListViewExtrasEnabled 决定了Header,Footer以何种方式加入mPullRefreshListView,true为headView方式加入,就是滚动时刷新头部会一起滚动。

注:上述属性很多都可以代码控制,如果有需要可以直接mPullRefreshListView.set属性名 查看
