问题描述：

我正在使用新的 Jetpack Android导航与抽屉布局"结合使用.当在Drawer XML中使用相同的ID并与Navigation Graph中的Fragments一起使用时，一切都按预期进行.我设置了所有内容:

I am using the new Jetpack Android Navigation in combination with a Drawer Layout. Everything is working as expected when using the same IDs in the Drawer XML in combination with Fragments in the Navigation Graph. I set everything up with:

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

        val navController = findNavController(R.id.navigation_host_fragment)
        setupActionBarWithNavController(navController, find(R.id.drawer_layout))
        val navigationView = findViewById<NavigationView>(R.id.nav_view)
        navigationView.setupWithNavController(findNavController(R.id.navigation_host_fragment))
}

     true
