}

补充：在使用过程中出现了向左滑动会出现空白页面的现象，以及IllegalStateException的问题，经过尝试找到了以下解决方法：

LoopPagerAdapter中

 @Overridepublic void destroyItem(ViewGroup container, int position, Object object) {//container.removeView((View) object);//注掉以后就不会出现空白页面}@Overridepublic Object instantiateItem(ViewGroup container, int position) {int realPosition = position%getRealCount();View itemView = findViewByPosition(container,realPosition);<span style="color:#ff0000;"> ViewGroup p = (ViewGroup) itemView.getParent();<span style="white-space:pre">   </span>//防止出现IllegalStateException异常if (p != null) {p.removeView(itemView);}<span style="white-space:pre">          </span></span>container.addView(itemView);return itemView;}
