ViewPager的使用方法和实现过程

看图先：

页面中填充内容是随机关键词飞入和飞出动画效果，随后会更新，现在请先无视吧

首先是 导入jar包   下载地址： android-support-v4.jar

布局文件里添加viewPager布局

public class ViewPagerAdapter extends PagerAdapter{    List<View> viewLists;        public ViewPagerAdapter(List<View> lists)    {        viewLists = lists;    }    @Override    public int getCount() {                                                                 //获得size        // TODO Auto-generated method stub        return viewLists.size();    }    @Override    public boolean isViewFromObject(View arg0, Object arg1) {                                 // TODO Auto-generated method stub        return arg0 == arg1;    }        @Override    public void destroyItem(View view, int position, Object object)                       //销毁Item    {        ((ViewPager) view).removeView(viewLists.get(position));    }        @Override    public Object instantiateItem(View view, int position)                                //实例化Item    {        ((ViewPager) view).addView(viewLists.get(position), 0);                return viewLists.get(position);    }    }
