我有一个问题，我的导航，首先我有一个碎片，其中有一个回收视图，当我使用导航移动到另一个碎片（B片段），回到我的A片段，我似乎无法点击回收器视图中包含的项目，它引发了我“查看androidx.constraintlayout.widget.constraintLayout{1f 8 e1 b2 V.E............. 0，0- 1080，1823}没有NavController集””。如果我不在Beetween片段中移动（停留在片段中），它工作得很好。
适配器上的onItemClicked调用findNavController（）。

class MainActivity : AppCompatActivity() {
    private lateinit var binding: ActivityMainMenuBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        startUI()

        val navHostFragment = supportFragmentManager.findFragmentById(R.id.nav_host) as NavHostFragment
        navController = navHostFragment.navController

    private fun replaceFragment(fragment : Fragment){

        val fragmentManager = supportFragmentManager
        val fragmentTransaction = fragmentManager.beginTransaction()
        fragmentTransaction.replace(R.id.nav_host,fragment)
        fragmentTransaction.commit()

这是我如何在RecipeListingFragment中初始化我的适配器：
'

private val adapter by lazy {
    RecipeListingAdapter(
        onItemClicked = {pos,item ->

            findNavController().navigate(R.id.action_receitaListingFragment_to_receitaDetailFragment,Bundle().apply {

                putParcelable("note",item)
            })
        },
        this.authModel
    )
}

'
这是我如何在RecipeListingFragment中设置我的适配器：
'

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    binding.recyclerView.adapter = adapter
}
