方法removeAllTabs()从Tablayout中无效

我面临着这个问题:每次我从Tablayout的标签都不会被删除

我在里面添加标签 onCreateView 把它们移到里面去 onDetach

但当我回到这里 fragment ,我的标签继续 tabLayout

class ProductsFragment : Fragment(), TabLayout.OnTabSelectedListener {

    private var tabLayout: TabLayout? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ...
        tabLayout = activity!!.findViewById(R.id.tablayout)
        ...
    }

    ...

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        //here I'm adding the tabs to tabLayout
    }

    ...

    override fun onDetach() {
        super.onDetach()
        tabLayout?.removeAllTabs()
    }
}
