Pengontrol navigasi adalah salah satu konsep utama dalam navigasi. Pengontrol
ini menyimpan grafik navigasi dan menampilkan metode yang memungkinkan aplikasi Anda berpindah
antar-tujuan dalam grafik.
Saat menggunakan komponen Navigation, Anda membuat pengontrol navigasi
menggunakan class NavController. NavController adalah API
navigasi pusat. API ini melacak tujuan yang telah dikunjungi pengguna, dan memungkinkan
pengguna berpindah-pindah antar-tujuan. Panduan ini menunjukkan cara membuat
NavController di aplikasi Anda.
Untuk informasi tentang cara menambahkan grafik navigasi ke NavController, lihat
Mendesain grafik navigasi. NavController menyediakan beberapa cara
untuk menavigasi ke tujuan dalam grafiknya. Untuk mengetahui selengkapnya, lihat Menavigasi ke
tujuan.
Compose
Untuk membuat NavController saat menggunakan Jetpack Compose, panggil
rememberNavController():
valnavController=rememberNavController()
Anda harus membuat NavController tinggi dalam hierarki composable. Posisinya
harus cukup tinggi sehingga semua composable yang perlu mereferensikannya dapat
melakukannya.
Dengan begitu, Anda dapat menggunakan NavController sebagai satu sumber tepercaya untuk
mengupdate composable di luar layar. Hal ini mengikuti prinsip
pengangkatan status.
View
Jika menggunakan framework UI View, Anda dapat mengambil NavController
menggunakan salah satu dari metode berikut, bergantung pada konteksnya.

ke NavController yang berisi semua tujuan di aplikasi Anda.

It\nholds the navigation graph and exposes methods that allow your app to move\nbetween the destinations in the graph.\n\nWhen using the [Navigation component](/reference/androidx/navigation/package-summary), you create a navigation controller\nusing the [`NavController`](/reference/androidx/navigation/NavController) class. [`NavController`](/reference/androidx/navigation/NavController) is the central\nnavigation API. It tracks which destinations the user has visited, and allows\nthe user to move between destinations. This guide demonstrates how to create a\n`NavController` in your app.\n\nFor information on how to add a navigation graph to your `NavController`, see\n[Design your navigation graph](/guide/navigation/design). `NavController` provides a few different ways\nto navigate to the destinations in its graph. For more, see [Navigate to a\ndestination](/guide/navigation/use-graph/navigate).\n| **Note:** Each `NavHost` you create has its own corresponding `NavController`. The `NavController` provides access to the `NavHost`'s graph.\n\nCompose\n-------\n\nTo create a `NavController` when using Jetpack Compose, call\n[`rememberNavController()`](/reference/kotlin/androidx/navigation/compose/package-summary#rememberNavController(kotlin.Array)): \n\n val navController = rememberNavController()\n\nYou should create the `NavController` high in your composable hierarchy. It\nneeds to be high enough that all the composables that need to reference it can\ndo so.\n\nDoing so lets you to use the `NavController` as the single source of truth for\nupdating composables outside of your screens. This follows the principles of\n[state hoisting](/jetpack/compose/state#state-hoisting).\n\nViews\n-----\n\nIf you are using the Views UI framework, you can retrieve your NavController\nusing one of the following methods depending on the context:\n\n**Kotlin:**\n\n- [`Fragment.findNavController()`](/reference/kotlin/androidx/navigation/fragment/package-summary#(androidx.fragment.app.Fragment).findNavController())\n- [`View.findNavController()`](/reference/kotlin/androidx/navigation/package-summary#%28android.view.View%29.findNavController%28%29)\n- [`Activity.findNavController(viewId: Int)`](/reference/kotlin/androidx/navigation/package-summary#(android.app.Activity).findNavController(kotlin.Int))\n\n**Java:**\n\n- [`NavHostFragment.findNavController(Fragment)`](/reference/androidx/navigation/fragment/NavHostFragment#findNavController(androidx.fragment.app.Fragment))\n- [`Navigation.findNavController(Activity, @IdRes int viewId)`](/reference/androidx/navigation/Navigation#findNavController(android.app.Activity,%20int))\n- [`Navigation.findNavController(View)`](/reference/androidx/navigation/Navigation#findNavController(android.view.View))\n\nTypically, you first get a `NavHostFragment`, and then retrieve the\n`NavController` from the fragment. The following snippet demonstrates this: \n\n### Kotlin\n\n val navHostFragment =\n supportFragmentManager.findFragmentById(R.id.nav_host_fragment) as NavHostFragment\n val navController = navHostFragment.navController\n\n### Java\n\n NavHostFragment navHostFragment =\n (NavHostFragment) getSupportFragmentManager().findFragmentById(R.id.nav_host_fragment);\n NavController navController = navHostFragment.getNavController();\n\n| **Warning:** You can encounter problems when creating the `NavHostFragment` using `FragmentContainerView` or when manually adding the `NavHostFragment` to your activity using a `FragmentTransaction`. If you do so, you can cause `Navigation.findNavController(Activity, @IdRes int)` to fail if you attempt to retrieve the `NavController` in `onCreate()`. You should retrieve the `NavController` directly from the `NavHostFragment` instead, as in the preceding example.\n\nFurther reading\n---------------\n\n- **[Design your navigation graph](/guide/navigation/design):** A guide detailing how to add a graph to your `NavController` that contains all the destinations in your app.\n- **[Navigate to a destination](/guide/navigation/use-graph/navigate):** A guide detailing how to use the `NavController` to move between destinations in your navigation graph."]]
