NavigationDrawer navigation drawer) is a panel that transitions from the left edge of the screen and displays the main navigation operations of the app.
Show Navigation Drawer
You can slide the slider from the left edge of the screen or click the icon on the ActionBar of the app to display the Navigation Drawer to the screen.
As an extension of NavigationDrawer, it overwrites the main content except ActionBar. When the navigation drawer is fully expanded, ActionBar replaces the ActionBar with the current app name and removes all views dominated by the navigation drawer. The overflow menu of standard operation items with Setting and Help operations is still displayed.
Because they are short-lived, navigation drawers reduce view confusion. You can also use them to lower levels in the navigation level, allowing users to switch from anywhere in the app to other important pages.
