/**
*
* This annotation is intended to be used on methods to receive events defined
* by
* android.support.v4.view.ViewPager.OnPageChangeListener.onPageScrollStateChanged
* when the scroll state changes.
*
*
* The annotation value should be one or several R.id.* fields that refers to
* ViewPager or subclasses of ViewPager. If not set, the method name will be
* used as the R.id.* field name.
*
*
* The method MAY have multiple parameter :
*
*
* - A ViewPager parameter to know which view has targeted this event
* - An int parameter is to get new scroll state.
*
*
*
*
* Examples :
*
*
* @PageScrollStateChanged(R.id.viewpager)
* void onPageScrollStateChanged(ViewPager view, int state) {
* // Something Here
* }
*
* @PageScrollStateChanged
* void viewPager(ViewPager view) {
* // Something Here
* }
*
* @PageScrollStateChanged({R.id.viewpager, R.id.viewpager2})
* void onPageScrollStateChangedOnMultipleViewPager(ViewPager v, int anything) {
* // Something Here
* }
*
* @PageScrollStateChanged(R.id.viewpager)
* void onPageScrollStateChangedNoParam() {
* // Something Here
* }
*
*
*
*
* @see PageScrolled
* @see PageSelected
