Menu in Android (Define,Create,Inflate and Click Handler)

In Android, a **menu** provides options for user actions and navigation in an app. Menus can appear as **options menus** (accessed via the app bar), **context menus** (triggered by long-press), or **popup menus** (small floating lists). They are typically defined in XML using `<menu>` and `<item>` tags and inflated using `MenuInflater` in activities or fragments. Developers handle menu item clicks using `onOptionsItemSelected()` or similar methods. Menus help improve usability by grouping actions in a consistent interface. Common use cases include settings, search, and sharing options, offering a clean and accessible way to enhance app functionality. Menus in Android offer a consistent and user-friendly way to present actions and navigation options within an app. By using options menus for global actions, context menus for specific UI elements, and popup menus for flexible interaction, developers can enhance the overall usability and functionality of their applications. Proper implementation of menus not only organizes actions effectively but also improves the user experience by making key features easily accessible.
