How to Enable Full-Screen Mode in Android?

In this article, we are going to learn how to enable full screen in Android Studio. Like if we are especially viewing an image then we want to view that on full screen. Here what we are going to implement is that we are basically hiding the navigation, status bar, and enabling the full-screen mode. We are going to discuss 4 different methods for doing this task.

Method 1

Following is the code to hide the navigation and enabling full-screen mode.

// This is the code to hide the navigation and enabling full screen mode
View.SYSTEM_UI_FLAG_IMMERSIVE
                            // Set the content to appear under the system bars so that the
                            // content doesn't resize when the system bars hide and show.
                            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            // Hide the nav bar and status bar
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN);
