我有5个item在BottomNavigationBar在MainActivity类中。当打开EarningFragment时，它有FragmentContairView，它从EarningFragment打开MoneyDetailFragment。当我打开这个MoneyDetailFragment时，它打开了。
在这个场景中，当单击BottomNavigationBar上的另一个项目，然后再次单击EarningFragment的项目时，它会记住MoneyDetailFragment中的项目，并打开这个类。我不想让它记起来在哪。我希望它只打开EarningFragment时，点击它在BottomNavigationBar。太复杂了，希望你能理解。
MainActivity.kt

class MainActivity : AppCompatActivity(), NavController.OnDestinationChangedListener,
                     View.OnClickListener {
private lateinit var navHostFragment: NavHostFragment

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
navHostFragment =
            supportFragmentManager.findFragmentById(R.id.nav_host_fragment) as NavHostFragment
 navHostFragment.navController.addOnDestinationChangedListener(this)
}
     private fun setupBottomNavigationView() {
     BottomNavigationViewHelper.setupBottomNavigationView(binding.bottomBar.bottomNavViewBar)
     binding.bottomBar.bottomNavViewBar.setupWithNavController(navHostFragment.navController)
        }
}
