Android Fragments 如何防止在BottomNavigation的Main fragmet中重新打开碎片？

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)
        }
}

字符串
nav_graph_main.xml

        xmlns:app="http://schemas.android.com/apk/res-auto"

    <fragment
        android:id="@+id/miEarnings"
        android:name="com.mi.ui.earning.EarningFragment"
        android:label="@string/menu_bottom_earnings"
        tools:layout="@layout/fragment_earning">
        <action

        <action
            android:id="@+id/action_to_moneyDetailFragment"
            app:destination="@id/moneyDetailFragment" />
    </fragment>

@DavidWasser非常感谢你。用户为“饼干”命名的第二个链接，我从它解决。我将这些代码添加到MainActivity中，以清除要打开的导航状态。

binding.bottomBar.bottomNavViewBar.setOnItemSelectedListener {
            when (it.itemId) {
                R.id.miHome -> {
                    navHostFragment.navController.navigate(R.id.miHome)
                    true
                }
                R.id.miBarcode -> {
                    navHostFragment.navController.navigate(
                        R.id.miBarcode,
                        null,
                        NavOptions.Builder()
                            .setPopUpTo(R.id.miBarcode, true)
                            .build())
                    true
                }
                R.id.miEarnings -> {
                    navHostFragment.navController.navigate(
                        R.id.miEarnings,
                        null,
                        NavOptions.Builder()
                            .setPopUpTo(R.id.miEarnings, true)
                            .build())
                    true
                }
                R.id.miProfil -> {
                    navHostFragment.navController.navigate(
                        R.id.miProfil,
                        null,
                        NavOptions.Builder()
                            .setPopUpTo(R.id.miProfil, true)
                            .build())
                    true
                }
                else -> {
                    navHostFragment.navController.navigate(R.id.miHome)
                    true
                }
            }
        }
