Masquer les barres système pour le mode immersif
Restez organisé à l'aide des collections
Enregistrez et classez les contenus selon vos préférences.
Certains contenus sont plus agréables à regarder en plein écran, sans indicateurs dans la barre d'état ni dans la barre de navigation. Il peut s'agir, par exemple, de vidéos, de jeux, de galeries d'images, de livres ou de diapositives de présentation. Il s'agit du mode immersif. Cette page explique comment engager davantage les utilisateurs avec du contenu en plein écran.
Figure 1 : Exemple de mode immersif.
Le mode immersif aide les utilisateurs à éviter les sorties accidentelles pendant un jeu et offre une expérience immersive pour profiter des images, des vidéos et des livres.
Toutefois, tenez compte de la fréquence à laquelle les utilisateurs passent d'une application à une autre pour consulter des notifications, effectuer des recherches impromptues ou effectuer d'autres actions. Étant donné que le mode immersif empêche les utilisateurs d'accéder facilement à la navigation système, n'utilisez ce mode que lorsque l'expérience utilisateur en bénéficie plus que si vous utilisiez simplement un espace d'écran supplémentaire.
Utilisez WindowInsetsControllerCompat.hide()
pour masquer les barres système et WindowInsetsControllerCompat.show()
pour les afficher à nouveau.
L'extrait de code suivant montre comment configurer un bouton pour masquer et afficher les barres système.
Kotlin
override fun onCreate(savedInstanceState: Bundle?) {
...
val windowInsetsController =
WindowCompat.getInsetsController(window, window.decorView)
// Configure the behavior of the hidden system bars.
windowInsetsController.systemBarsBehavior =
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
// Add a listener to update the behavior of the toggle fullscreen button when
// the system bars are hidden or revealed.
ViewCompat.setOnApplyWindowInsetsListener(window.decorView) { view, windowInsets ->
// You can hide the caption bar even when the other system bars are visible.
// To account for this, explicitly check the visibility of navigationBars()
// and statusBars() rather than checking the visibility of systemBars().
if (windowInsets.isVisible(WindowInsetsCompat.Type.navigationBars())
|| windowInsets.isVisible(WindowInsetsCompat.Type.statusBars())) {
binding.toggleFullscreenButton.setOnClickListener {
// Hide both the status bar and the navigation bar.
windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())
}
} else {
binding.toggleFullscreenButton.setOnClickListener {
// Show both the status bar and the navigation bar.
windowInsetsController.show(WindowInsetsCompat.Type.systemBars())
}
}
ViewCompat.onApplyWindowInsets(view, windowInsets)
}
}
Java
@Override
protected void onCreate(Bundle savedInstanceState) {
...
WindowInsetsControllerCompat windowInsetsController =
WindowCompat.getInsetsController(getWindow(), getWindow().getDecorView());
// Configure the behavior of the hidden system bars.
windowInsetsController.setSystemBarsBehavior(
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
);
// Add a listener to update the behavior of the toggle fullscreen button when
// the system bars are hidden or revealed.
ViewCompat.setOnApplyWindowInsetsListener(
getWindow().getDecorView(),
(view, windowInsets) -> {
// You can hide the caption bar even when the other system bars are visible.
// To account for this, explicitly check the visibility of navigationBars()
// and statusBars() rather than checking the visibility of systemBars().
if (windowInsets.isVisible(WindowInsetsCompat.Type.navigationBars())
|| windowInsets.isVisible(WindowInsetsCompat.Type.statusBars())) {
binding.toggleFullscreenButton.setOnClickListener(v -> {
// Hide both the status bar and the navigation bar.
windowInsetsController.hide(WindowInsetsCompat.Type.systemBars());
});
} else {
binding.toggleFullscreenButton.setOnClickListener(v -> {
// Show both the status bar and the navigation bar.
windowInsetsController.show(WindowInsetsCompat.Type.systemBars());
});
}
return ViewCompat.onApplyWindowInsets(view, windowInsets);
});
}
Vous pouvez éventuellement spécifier le type de barres système à masquer et déterminer leur comportement lorsqu'un utilisateur interagit avec elles.
Spécifier les barres système à masquer
Pour spécifier le type de barres système à masquer, transmettez l'un des paramètres suivants à WindowInsetsControllerCompat.hide()
.
Spécifier le comportement des barres système masquées

[null,null,["Dernière mise à jour le 2025/08/27 (UTC)."],[],[],null,["Some content is best experienced in fullscreen without any indicators on the\nstatus bar or the navigation bar. Some examples are videos, games, image\ngalleries, books, and presentation slides. This is referred to as\n*immersive mode*. This page shows how you can engage users more deeply with\ncontent in fullscreen. \n**Figure 1.** Example of immersive mode.\n\nImmersive mode helps users avoid accidental exits during a game and\ndelivers an immersive experience for enjoying images, videos, and books.\nHowever, be mindful of how often users jump in and out of apps to check notifications,\nto conduct impromptu searches, or to take other actions. Because immersive mode\ncauses users to lose easy access to system navigation, use immersive mode only\nwhen the benefit to the user experience goes beyond simply using extra screen\nspace.\n\nUse [`WindowInsetsControllerCompat.hide()`](/reference/androidx/core/view/WindowInsetsControllerCompat#hide(int))\nto hide the system bars and [`WindowInsetsControllerCompat.show()`](/reference/androidx/core/view/WindowInsetsControllerCompat#show(int))\nto bring them back.\n\nThe following snippet shows an example of configuring a button to hide and show\nthe system bars. \n\nKotlin \n\n```kotlin\noverride fun onCreate(savedInstanceState: Bundle?) {\n ...\n\n val windowInsetsController =\n WindowCompat.getInsetsController(window, window.decorView)\n // Configure the behavior of the hidden system bars.\n windowInsetsController.systemBarsBehavior =\n WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE\n\n // Add a listener to update the behavior of the toggle fullscreen button when\n // the system bars are hidden or revealed.\n ViewCompat.setOnApplyWindowInsetsListener(window.decorView) { view, windowInsets -\u003e\n // You can hide the caption bar even when the other system bars are visible.\n // To account for this, explicitly check the visibility of navigationBars()\n // and statusBars() rather than checking the visibility of systemBars().\n if (windowInsets.isVisible(WindowInsetsCompat.Type.navigationBars())\n || windowInsets.isVisible(WindowInsetsCompat.Type.statusBars())) {\n binding.toggleFullscreenButton.setOnClickListener {\n // Hide both the status bar and the navigation bar.\n windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())\n }\n } else {\n binding.toggleFullscreenButton.setOnClickListener {\n // Show both the status bar and the navigation bar.\n windowInsetsController.show(WindowInsetsCompat.Type.systemBars())\n }\n }\n ViewCompat.onApplyWindowInsets(view, windowInsets)\n }\n}\n```\n\nJava \n\n```java\n@Override\nprotected void onCreate(Bundle savedInstanceState) {\n ...\n\n WindowInsetsControllerCompat windowInsetsController =\n WindowCompat.getInsetsController(getWindow(), getWindow().getDecorView());\n // Configure the behavior of the hidden system bars.\n windowInsetsController.setSystemBarsBehavior(\n WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE\n );\n\n // Add a listener to update the behavior of the toggle fullscreen button when\n // the system bars are hidden or revealed.\n ViewCompat.setOnApplyWindowInsetsListener(\n getWindow().getDecorView(),\n (view, windowInsets) -\u003e {\n // You can hide the caption bar even when the other system bars are visible.\n // To account for this, explicitly check the visibility of navigationBars()\n // and statusBars() rather than checking the visibility of systemBars().\n if (windowInsets.isVisible(WindowInsetsCompat.Type.navigationBars())\n || windowInsets.isVisible(WindowInsetsCompat.Type.statusBars())) {\n binding.toggleFullscreenButton.setOnClickListener(v -\u003e {\n // Hide both the status bar and the navigation bar.\n windowInsetsController.hide(WindowInsetsCompat.Type.systemBars());\n });\n } else {\n binding.toggleFullscreenButton.setOnClickListener(v -\u003e {\n // Show both the status bar and the navigation bar.\n windowInsetsController.show(WindowInsetsCompat.Type.systemBars());\n });\n }\n return ViewCompat.onApplyWindowInsets(view, windowInsets);\n });\n}\n```\n\nOptionally, you can specify the type of system bars to hide and determine\ntheir behavior when a user interacts with them.\n\nSpecify which system bars to hide\n\nTo specify the type of system bars to hide, pass one of the following parameters\nto `WindowInsetsControllerCompat.hide()`.\n\n- Use [`WindowInsetsCompat.Type.systemBars()`](/reference/kotlin/androidx/core/view/WindowInsetsCompat.Type#systembars) to\n hide both system bars.\n\n- Use [`WindowInsetsCompat.Type.statusBars()`](/reference/kotlin/androidx/core/view/WindowInsetsCompat.Type#statusbars) to\n hide only the status bar.\n\n- Use [`WindowInsetsCompat.Type.navigationBars()`](/reference/kotlin/androidx/core/view/WindowInsetsCompat.Type#navigationbars) to\n hide only the navigation bar.\n\nSpecify behavior of hidden system bars\n\nUse [`WindowInsetsControllerCompat.setSystemBarsBehavior()`](/reference/androidx/core/view/WindowInsetsControllerCompat#setSystemBarsBehavior(int))\nto specify how hidden system bars behave when the user interacts with them.\n\n- Use [`WindowInsetsControllerCompat.BEHAVIOR_SHOW_BARS_BY_TOUCH`](/reference/androidx/core/view/WindowInsetsControllerCompat#BEHAVIOR_SHOW_BARS_BY_TOUCH())\n to reveal hidden system bars on *any* user interactions on the corresponding\n display.\n\n- Use [`WindowInsetsControllerCompat.BEHAVIOR_SHOW_BARS_BY_SWIPE`](/reference/androidx/core/view/WindowInsetsControllerCompat#BEHAVIOR_SHOW_BARS_BY_SWIPE())\n to reveal hidden system bars on any system gestures, such as swiping from\n the edge of the screen where the bar is hidden from.\n\n- Use [`WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE`](/reference/androidx/core/view/WindowInsetsControllerCompat#BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE())\n to temporarily reveal hidden system bars with system gestures, such as\n swiping from the edge of the screen where the bar is hidden from. These\n transient system bars overlay your app's content, might have some degree of\n transparency, and are automatically hidden after a short timeout."]]
