  /**
   * <p>
   * This annotation is intended to be used on methods to receive events defined
   * by
   * <code>android.support.v4.view.ViewPager.OnPageChangeListener.OnPageScrolled</code>
   * when the current page is scrolled, either as part of a programmatically
   * initiated smooth scroll or a user initiated touch scroll.
   * </p>
   * <p>
   * 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.
   * </p>
   * <p>
   * The method MAY have multiple parameters, but the order must be following :
   * </p>
   * <ul>
   * <li>A ViewPager parameter to know which view has targeted this event.</li>
   * <li>An int parameter named position to get position index of the first page
   * currently being displayed. Page position+1 will be visible if positionOffset
   * is nonzero.</li>
   * <li>A float parameter is value from [0,1) indicating the offset from the page
   * at position.</li>
   * <li>An int parameter named positionOffsetPixels is value in pixels indicating
   * the offset from position.</li>
   * </ul>
   *
   * <blockquote>
   *
   * Examples :
   *
   * <pre>
   * &#064;PageScrolled(<b>R.id.viewpager</b>)
   * void onPageScrolled(ViewPager view, int position, float positionOffset, int positionOffsetPixels) {
   * 	// Something Here
   * }
   *
   * &#064;PageScrolled
   * void viewPager(ViewPager view) {
   * 	// Something Here

   * &#064;PageScrolled(<b>{R.id.viewpager, R.id.viewpager2}</b>)
