Android开发实用Navigation怎么改变导航栏图标、字体颜色，如何去掉标题栏？请看这里。

1、废话不多，直接上代码：

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

        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)
        supportActionBar?.hide()

        val navView: BottomNavigationView = binding.navView

        val navController = findNavController(R.id.nav_host_fragment_activity_main)

        val appBarConfiguration = AppBarConfiguration(
            setOf(
                R.id.navigation_home, R.id.navigation_dashboard, R.id.navigation_notifications
            )
        )
        setupActionBarWithNavController(navController, appBarConfiguration)
        navView.setupWithNavController(navController)
        @SuppressLint("ResourceType")
        val colorState: ColorStateList = resources.getColorStateList(
            R.drawable.ic_notifications_black_24dp,
            resources.newTheme()
