ViewPager报UnsupportedOperationException: Required method instantiateItem was not overridden错误

写一个简单的viewpager出现了下面这个报错信息。

提示我们需要重写 instantiateItem方法：

解决问题：adapter里边重写instantiateItem方法并改为如下所示。

public class PicCarouseVpAdapter extends PagerAdapter {private List<View> pageList;public PicCarouseVpAdapter(List<View> pageList) {this.pageList = pageList;}@Overridepublic int getCount() {// TODO Auto-generated method stub// 返回要展示的图片数量return pageList.size();}@Overridepublic boolean isViewFromObject(View arg0, Object arg1) {// TODO Auto-generated method stub// 刚开始用viewpager就直接写“return arg0 == arg1;”就好啦return arg0 == arg1;}@Overridepublic Object instantiateItem(ViewGroup container, int position) {container.addView(pageList.get(position));//每次滑动的时候把视图添加到viewpagerreturn pageList.get(position);}@Overridepublic void destroyItem(ViewGroup container, int position, Object object) {// TODO Auto-generated method stub// 将当前位置的View移除container.removeView(pageList.get(position));}
}
