Ocultar barras de sistema para o modo imersivo
Mantenha tudo organizado com as coleções
Salve e categorize o conteúdo com base nas suas preferências.
Alguns conteúdos ficam melhores em tela cheia sem indicadores na barra de status ou de navegação. Alguns exemplos são vídeos, jogos, galerias de imagens, livros e slides de apresentação. Isso é chamado de modo imersivo. Esta página mostra como você pode envolver os usuários mais profundamente com
conteúdo em tela cheia.
Figura 1. Exemplo do modo imersivo.
O modo imersivo ajuda os usuários a evitar saídas acidentais durante um jogo e
oferece uma experiência imersiva para aproveitar imagens, vídeos e livros.
No entanto, preste atenção à frequência com que os usuários entram e saem de apps para verificar notificações,
fazer pesquisas de improviso ou realizar outras ações. Como o modo imersivo faz com que os usuários percam o acesso fácil à navegação do sistema, use-o apenas quando o benefício para a experiência do usuário for além do uso de espaço extra na tela.
Use WindowInsetsControllerCompat.hide()
para ocultar as barras de sistema e WindowInsetsControllerCompat.show()
para mostrá-las novamente.
O snippet a seguir mostra um exemplo de configuração de um botão para ocultar e mostrar
as barras de sistema.
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);
});
}
Opcionalmente, você pode especificar o tipo de barras de sistema a serem ocultadas e determinar
o comportamento delas quando um usuário interage com elas.
Especificar quais barras de sistema ocultar
Para especificar o tipo de barras de sistema a serem ocultadas, transmita um dos seguintes parâmetros para WindowInsetsControllerCompat.hide()
.
Especificar o comportamento das barras de sistema ocultas
Use WindowInsetsControllerCompat.setSystemBarsBehavior()
para especificar como as barras de sistema ocultas se comportam quando o usuário interage com elas.

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

{\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."]]
