Android dynamic display and hide status bar details and examples

Android dynamically shows and hides the status bar

1. View.SYstem_ UI_ FLAG_ Visible: the status bar is displayed, and the activity is not displayed in full screen (restored to the normal condition with status). 2. View.invisible: hide the status bar, and the activity will be displayed in full screen. 3. View.SYstem_ UI_ FLAG_ Fullscreen: the activity is displayed in full screen, and the status bar is hidden and overwritten. 4.
