How to set full screen android with top bar năm 2024

Some content is best experienced in fullscreen without any indicators on the status bar or the navigation bar. Some examples are videos, games, image galleries, books, and presentation slides. This is referred to as immersive mode. This page shows how you can engage users more deeply with content in fullscreen.

Figure 1. Example of immersive mode.

Immersive mode helps users avoid accidental exits during a game and delivers an immersive experience for enjoying images, videos, and books. However, be mindful of how often users jump in and out of apps to check notifications, to conduct impromptu searches, or to take other actions. Because immersive mode causes users to lose easy access to system navigation, use immersive mode only when the benefit to the user experience goes beyond simply using extra screen space.

Use to hide the system bars and to bring them back.

The following snippet shows an example of configuring a button to hide and show the system bars.

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.
window.decorView.setOnApplyWindowInsetsListener { 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())
        }
    }
    view.onApplyWindowInsets(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.
getWindow().getDecorView().setOnApplyWindowInsetsListener((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 view.onApplyWindowInsets(windowInsets);
});

Optionally, you can specify the type of system bars to hide and determine their behavior when a user interacts with them.

Specify which system bars to hide

To specify the type of system bars to hide, pass one of the following parameters to WindowInsetsControllerCompat.hide().

• Use to hide both system bars.
• Use to hide only the status bar.
• Use to hide only the navigation bar.

Specify behavior of hidden system bars

Use to specify how hidden system bars behave when the user interacts with them.

• Use to reveal hidden system bars on any user interactions on the corresponding display.
• Use to reveal hidden system bars on any system gestures, such as swiping from the edge of the screen where the bar is hidden from.
• Use to temporarily reveal hidden system bars with system gestures, such as swiping from the edge of the screen where the bar is hidden from. These transient system bars overlay your app’s content, might have some degree of transparency, and are automatically hidden after a short timeout.
