直接看代码：

private class ViewPagerAdapter extends PagerAdapter {

    // 获取要滑动的控件的数量
    @Override
    public int getCount() {
        return images.size();
    }

    // 来判断显示的是否是同一个view
    @Override
    public boolean isViewFromObject(View arg0, Object arg1) {
        return arg0 == arg1;
    }

    @Override
    public void destroyItem(ViewGroup view, int position, Object object) {
        view.removeView(images.get(position));
    }

    @Override
    public Object instantiateItem(ViewGroup view, int position) {
        view.addView(images.get(position));
        return images.get(position);
    }
}
