Extending the activity to Status bar - (Android Essentials: XML & Java)
Immerse your users more deeply by extending the app's UI to underlay the status bar, creating a seamless look on the screen. The code snippet provided enables your application to display its layout content in a mode where the system's status bar remains overlaid on top of the app's window, extending the app's content all the way to the top edge of the screen.
This effect is achieved by setting flags on the window that instruct the Android system to place the activity's layout in the entire screen, including the areas traditionally reserved for the system UI like the status bar. The flags used are:
FLAG_LAYOUT_IN_SCREEN: This flag lets the window be laid out as if it would fill the entire screen, regardless of actual system decorations like status bars.
FLAG_LAYOUT_NO_LIMITS: With this flag, the system does not restrict the layout of the window to the usual content area. The layout extends beyond the system UI like navigation bars or the status bar, if necessary.
Here’s how you can use this snippet:
Copy the provided code.
Paste it into your Activity's
onCreatemethod or after your
setContentViewmethod call to ensure your UI layout extends beneath the system status bar.
Adjust your layout's padding or margins if necessary to account for the status bar height, to prevent important UI elements from being underlaid and thus, obscured by the status bar.
This setup is ideal for creating an immersive experience with background images or videos that extend to the very edge of the screen, providing a more expansive and visually pleasing user interface.
Note: Be cautious when using these flags as they can lead to UI elements being hidden behind the status bar, which can affect the usability of your app. Always make sure important information and interactive elements are within the visible bounds of the screen.
