如何制作 RTL appBarConfiguration androidx.navigation？

Question

我想制作 RTL appBarConfiguration。这是我的 MainActivity 代码。有什么方法可以帮助我在不使用自定义工具栏或进行一些自定义操作的情况下做到这一点？我搜索并发现这是 android 文档：[navigation-ui][1] 但如果有这样的东西，我会寻找像布局方向这样简单的东西

主要活动class:


    private lateinit var drawerLayout: DrawerLayout
    private lateinit var appBarConfiguration: AppBarConfiguration

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val binding =
            DataBindingUtil.setContentView<ActivityMainBinding>(this, R.layout.activity_main)
        drawerLayout = binding.drawerLayout

        val navController = this.findNavController(R.id.navHostFragment)
        appBarConfiguration = AppBarConfiguration(navController.graph, drawerLayout)
        NavigationUI.setupActionBarWithNavController(this, navController, drawerLayout)

        navController.addOnDestinationChangedListener { nc: NavController, nd: NavDestination, _: Bundle? ->
            if (nd.id == nc.graph.startDestination) {
                drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED)
            } else {
                drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED)
            }
        }

        NavigationUI.setupWithNavController(binding.navView, navController)
    }



    override fun onSupportNavigateUp(): Boolean {
        val navigationController = findNavController(R.id.navHostFragment)
        return navigationController.navigateUp(appBarConfiguration) || super.onSupportNavigateUp()
    }


    override fun onBackPressed() {
        if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
            drawerLayout.closeDrawer(GravityCompat.START)
        } else {
            return super.onBackPressed()
        }
    }
}

这里 activity_main.xml:

<layout xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>

    </data>

<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawerLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layoutDirection="rtl"
    tools:openDrawer="start"
    tools:context=".MainActivity">

    <fragment
        android:id="@+id/navHostFragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:defaultNavHost="true"
        app:navGraph="@navigation/navigation"/>


    <com.google.android.material.navigation.NavigationView
        android:id="@+id/navView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:menu="@menu/drawer_menu"
        app:headerLayout="@layout/fragment_cart"
        />



</androidx.drawerlayout.widget.DrawerLayout>
</layout>```

我可以通过在 activity_main.xml 和 MainActivity.kt

中添加此部分来修复它

activity_main.xml

<layout xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>

    </data>

<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawerLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layoutDirection="rtl"
    tools:openDrawer="start"
    tools:context=".MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.Dark" />

    <fragment
        android:id="@+id/navHostFragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:defaultNavHost="true"
        app:navGraph="@navigation/navigation"/>
    </LinearLayout>

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/navView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:menu="@menu/drawer_menu"
        app:headerLayout="@layout/fragment_cart"
        />



</androidx.drawerlayout.widget.DrawerLayout>
</layout> ```

MainActivity.kt:

``` class MainActivity : AppCompatActivity() {

    private lateinit var drawerLayout: DrawerLayout
    private lateinit var appBarConfiguration: AppBarConfiguration
    private lateinit var toolbar: androidx.appcompat.widget.Toolbar

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val binding =
            DataBindingUtil.setContentView<ActivityMainBinding>(this, R.layout.activity_main)
        drawerLayout = binding.drawerLayout
        toolbar = binding.toolbar


        setSupportActionBar(toolbar)
        //supportActionBar?.setDisplayHomeAsUpEnabled(true)
        //supportActionBar?.setDisplayShowHomeEnabled(true)

        val navController = this.findNavController(R.id.navHostFragment)
        appBarConfiguration = AppBarConfiguration(navController.graph, drawerLayout)
        NavigationUI.setupActionBarWithNavController(this, navController, drawerLayout)

        navController.addOnDestinationChangedListener { nc: NavController, nd: NavDestination, _: Bundle? ->
            if (nd.id == nc.graph.startDestination) {
                drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED)
            } else {
                drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED)
            }
        }

        NavigationUI.setupWithNavController(binding.navView, navController)
    }



    override fun onSupportNavigateUp(): Boolean {
        val navigationController = findNavController(R.id.navHostFragment)
        return navigationController.navigateUp(appBarConfiguration) || super.onSupportNavigateUp()
    }


    override fun onBackPressed() {
        if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
            drawerLayout.closeDrawer(GravityCompat.START)
        } else {
            return super.onBackPressed()
        }
    }
} ```

I hope this help someone.
