class KnolagePagerAdapter(val list: List<KonlageEntity.DataBean.ChildrenBean>,fm: FragmentManager?) : FragmentPagerAdapter(fm) {
override fun getItem(position: Int): Fragment {
var fragment = KnolageShowPagerFragment()//向指定的Fragment中传递参数
var bundle = Bundle(http://www.amjmh.com/v/BIBRGZ_558768/)
bundle.putString("wakaka",list.get(position).id)
fragment.arguments = bundle
return fragment

}

override fun getCount(): Int {
return list.size
}

override fun getPageTitle(position: Int): CharSequence? {
return list.get(position).name
}

}
