Question

我刚刚开始使用Android NavigationUI通过抽屉菜单实现片段导航。尽管它确实有点像魔术，但我有一个主要问题。也就是说，菜单中有一个logout项目，该项目不应该导航到任何“片段”，而应该导航到“动作”。尽管我在这里找到了类似的问题，例如this，但我还没有找到明确的答案。以下是我当前用于设置导航的功能：

private fun setupNav() {
    val binding: ActivityMainMenuBinding = DataBindingUtil.setContentView(this,
            R.layout.activity_main_menu)
    drawerLayout = binding.drawerLayout
    navController = Navigation.findNavController(this, R.id.content_frame)
    appBarConfiguration = AppBarConfiguration(navController.graph, drawerLayout)

    // Set up ActionBar
    setSupportActionBar(binding.toolbar)
    setupActionBarWithNavController(navController, appBarConfiguration)
    binding.navView.setupWithNavController(navController)
}

如果您对我的处理方法有任何建议，可以与您分享，我们将不胜感激。

您只需要添加以下提到的代码

    nav_view.menu.findItem(R.id.nav_logout).setOnMenuItemClickListener {
            Log.e("=>"," You clicked on logout !!! ")
            true
        }

这是我的完整代码

    class NavigationDrawerActivity : AppCompatActivity() {

    private lateinit var appBarConfig: AppBarConfiguration

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_navigation_drawer)
        setSupportActionBar(toolbar)

        val navController: NavController = findNavController(R.id.nav_host_fragment)

        appBarConfig = AppBarConfiguration(
            setOf(
                R.id.nav_home,
                R.id.nav_gallery,
                R.id.nav_slideshow,
                R.id.nav_tools,
                R.id.nav_share,
                R.id.nav_send
            )
            , drawer_layout
        )

        setupActionBarWithNavController(navController, appBarConfig)
        nav_view.setupWithNavController(navController)

        //For log out button related stuff
        nav_view.menu.findItem(R.id.nav_logout).setOnMenuItemClickListener {
            Log.e("=>"," You clicked on logout !!! ")
            true
        }
    }

    override fun onSupportNavigateUp(): Boolean {
        return findNavController(R.id.nav_host_fragment).navigateUp(appBarConfig)
                || super.onSupportNavigateUp()
    }
}
