Introduction

In this lesson, we’ll learn about menus in Android. You can create options menus, context menus, and popup menus in your Android apps, and each of these menus serves specific use cases.

Options menu

The options menu is considered the main menu for the activity. It should be used for allowing access to primary functionalities of the activity, such as “Search,” “Settings,” and “Help.” Let’s learn how to create an options menu in an Android app.

First, we need to define the layout for the menu containing the menu items, with the title and icon specified. Create a resource file called menu_options_menu.xml in res/menu and add the following contents to it.

    <item android:id="@+id/help"
        android:icon="@drawable/ic_help"
        android:title="@string/help" />

It tells Android to show this menu item in the action bar if there’s sufficient space, but otherwise, it shows it in the menu.

Step 2: Inflate the menu
