/**
 * 

* 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 */ @Retention(RetentionPolicy.CLASS) @Target(ElementType.METHOD) public @interface PageScrollStateChanged { /** * The R.id.* fields which refer to the ViewPager. * * @return the ids of the ViewPager. */ int[] value() default ResId.DEFAULT_VALUE; /** * The resource names as a strings which refer to the ViewPagers. * * @return the resource names of the ViewPagers. */ String[] resName() default ""; }
