ViewPager添加删除数据后刷新页面方法

覆写PagerAdapter的getItemPosition方法

    /**
     * 覆写此函数，才能使得删除数据后UI及时刷新
     */
    override fun getItemPosition(obj: Any): Int {
        return POSITION_NONE
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {

        View view = (View) object;
        container.removeView(view);
        view = null;
//        container.removeView(mViewList.get(position));
    }
