Systemleisten für immersiven Modus ausblenden
Mit Sammlungen den Überblick behalten
Sie können Inhalte basierend auf Ihren Einstellungen speichern und kategorisieren.
Einige Inhalte werden am besten im Vollbildmodus ohne Anzeigen in der Statusleiste oder der Navigationsleiste wiedergegeben. Dazu gehören zum Beispiel Videos, Spiele, Bildergalerien, Bücher und Präsentationsfolien. Das wird als Immersivmodus bezeichnet. Auf dieser Seite wird beschrieben, wie Sie Nutzer mit Inhalten im Vollbildmodus stärker einbinden können.
Abbildung 1. Beispiel für den immersiven Modus
Immersiver Modus hilft Nutzern, versehentliches Beenden während eines Spiels zu vermeiden, und bietet ein immersives Erlebnis beim Ansehen von Bildern, Videos und Büchern.
Achten Sie jedoch darauf, wie oft Nutzer Apps öffnen und schließen, um Benachrichtigungen zu prüfen, spontane Suchanfragen durchzuführen oder andere Aktionen auszuführen. Da Nutzer im Immersive-Modus keinen einfachen Zugriff auf die Systemnavigation haben, sollten Sie ihn nur verwenden, wenn die Vorteile für die Nutzer über die Nutzung von zusätzlichem Bildschirmplatz hinausgehen.
Verwenden Sie WindowInsetsControllerCompat.hide()
, um die Systemleisten auszublenden, und WindowInsetsControllerCompat.show()
, um sie wieder einzublenden.
Das folgende Snippet zeigt ein Beispiel für die Konfiguration einer Schaltfläche zum Ein- und Ausblenden der Systemleisten.
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);
});
}
Optional können Sie den Typ der zu verbergenden Systemleisten angeben und ihr Verhalten festlegen, wenn ein Nutzer mit ihnen interagiert.
Festlegen, welche Systemleisten ausgeblendet werden sollen
Um den Typ der Systemleisten anzugeben, die ausgeblendet werden sollen, übergeben Sie einen der folgenden Parameter an WindowInsetsControllerCompat.hide()
.
Verhalten ausgeblendeter Systemleisten festlegen
Verwenden Sie WindowInsetsControllerCompat.setSystemBarsBehavior()
, um anzugeben, wie sich ausgeblendete Systemleisten verhalten, wenn der Nutzer mit ihnen interagiert.

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."]]
