android-studio - 如何从抽屉菜单标题项导航到特定片段

Question

我正在使用导航组件进行导航

这是主屏幕

此处的主要活动代码：

lateinit var appBarConfiguration: AppBarConfiguration
lateinit var navController: NavController

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

    Utils.setStatusBarGradiant(this)
    setContentView(R.layout.activity_main)
    supportActionBar?.setBackgroundDrawable(getDrawable(R.drawable.gradient_theme))


   // bottom navigation
   navController = findNavController(R.id.nav_host_fragment)
   bottomNavigationView.setupWithNavController(navController)

   //Navigation UP Button
   appBarConfiguration = AppBarConfiguration(navController.graph, drawer_Layout)
   //create arrow button
   NavigationUI.setupActionBarWithNavController(this, navController, drawer_Layout)

  //Drawer Navigation
  NavigationUI.setupWithNavController(nav_view, navController)
}

 // click on arrow button ( back to home fragment function)
  override fun onSupportNavigateUp(): Boolean {
  return NavigationUI.navigateUp(navController, appBarConfiguration)

}

此处的主要活动 XML 文件：

这是导航抽屉菜单图片

我的问题是：当我点击导航抽屉菜单中的订单时，我想转到主活动中的订单片段
