Android应用引导界面-ViewPages使用

        // 初始化引导图片列表
        view1 = inflater.inflate(R.layout.page_one, null);
        view2 = inflater.inflate(R.layout.page_two, null);
        view3 = inflater.inflate(R.layout.page_three, null);
        viewList = new ArrayList<View>();// 将要分页显示的View装入数组中
        viewList.add(view1);
        viewList.add(view2);
        viewList.add(view3);
        viewPager = (ViewPager) findViewById(R.id.viewpager);
        // 初始化Adapter,重写PagerAdapter
        PagerAdapter pagerAdapter = new PagerAdapter() {
            @Override
            public boolean isViewFromObject(View view, Object object) {
                return view == object;//该object其实就是viewPager添加的view
            }
            @Override
            public int getCount() {
                return viewList.size();
            }
            @Override
            public void destroyItem(ViewGroup container, int position, Object object) {
                container.removeView(viewList.get(position));
            }
            @Override
            public int getItemPosition(Object object) {
                return super.getItemPosition(object);
            }
            @Override
            public CharSequence getPageTitle(int position) {
                return super.getPageTitle(position);
            }
            @Override
            public Object instantiateItem(View container, int position) {
                ((ViewPager)container).addView(viewList.get(position))；
                 return viewList.get(position);
            }
        };
        viewPager.setAdapter(pagerAdapter);
        // 绑定回调
