视图下拉刷新的功能

视图下拉刷新的功能,在各种View中加入下拉刷新(pull to refresh)功能。下拉刷新时,在视图View上方的ActionBar会被刷新的动画所代替,等刷新加载完毕,才重新显示ActionBar。 ActionBar-PullToRefresh provides an easy way to add a modern version of the pull-to-refresh interaction to your application. Please note that this is not an update to Android-PullToRefresh, this has been created from new. You should think of this as Android-PullToRefresh s younger, leaner cousin.
