  1. 这是我的主要活动
package com.ct07.ttn

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import androidx.lifecycle.ViewModelProvider
import androidx.navigation.fragment.NavHostFragment
import androidx.navigation.ui.setupWithNavController
import com.ct07.ttn.databinding.ActivityMainBinding
import com.ct07.ttn.repository.RoomRepository
import com.ct07.ttn.viewmodel.HomeViewModel
import com.ct07.ttn.viewmodel.HomeViewModelProviderFactory

class MainActivity : AppCompatActivity() {

    lateinit var homeViewModel: HomeViewModel
    lateinit var binding: ActivityMainBinding
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        val roomRepository = RoomRepository()
        val viewModelProviderFactory = HomeViewModelProviderFactory(application, roomRepository)
        homeViewModel = ViewModelProvider(this, viewModelProviderFactory).get(HomeViewModel::class.java)

        val navHostFragment = supportFragmentManager.findFragmentById(R.id.homeNavHostFragment) as NavHostFragment
        val navController = navHostFragment.navController
        binding.bottomNavigationView.setupWithNavController(navController)
    }
}
  1. 这是我的acitivity_main.xml
<?xml version="1.0" encoding="utf-8"?>

    </FrameLayout>

        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
  1. 这是我的 room_nav_graph.xml
<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/room_nav_graph"
    app:startDestination="@id/homeFragment">

    <fragment
        android:id="@+id/homeFragment"
        android:name="com.ct07.ttn.fragments.HomeFragment"
        android:label="HomeFragment" >
        <action
            android:id="@+id/action_homeFragment_to_roomFragment"
            app:destination="@id/roomFragment" />
    </fragment>
    <fragment
        android:id="@+id/favoriteFragment"
        android:name="com.ct07.ttn.fragments.FavoriteFragment"
        android:label="FavoriteFragment" >
        <action
            android:id="@+id/action_favoriteFragment_to_roomFragment"
            app:destination="@id/roomFragment" />
    </fragment>
    <fragment
        android:id="@+id/roomFragment"
        android:name="com.ct07.ttn.fragments.RoomFragment"
        android:label="RoomFragment" >
        <argument
            android:name="room"
            app:argType="com.ct07.ttn.models.Room"
            app:nullable="true" />
    </fragment>
</navigation>

我尝试了很多并观看论坛，但我找不到我的问题

Caused by: java.lang.IllegalArgumentException: com.ct07.ttn.models.Room is not Serializable or Parcelable

用于导航参数的自定义类需要实现

或 
Serializable
接口。请参阅文档了解导航参数的有效类型。
