Compose Action Menu

This library provides an easy-to-use action menu for Compose, since Compose doesn't offer this by default.

Features

• Icons (optional);
• Selectable/checkable items;
• Nested sub menus;
• Automatic overflow for items that don't fit the specified maximum.

Installation

repositories {
    google()
    maven { url "https://jitpack.io" }
}
dependencies {
    implementation "com.github.jacobras:ComposeActionMenu:1.0.0"
}

Usage

val toolbarActions = listOf(
    RegularActionItem(
        key = "settings",
        titleResId = R.string.settings,
        onClick = { /* TODO: Open settings screen */ }
    )
)

TopAppBar(
    actions = { ActionMenu(items = toolbarActions) }
)

Supported item types

Several different type of actions can be used. These are all sub classes of ActionItem.

• Regular item: RegularActionItem;
• Checkable item: CheckableActionItem;
• Radio-toggleable item: RadioActionItem;
• Groups: GroupActionItem.

Creating a group

Is as simple as:

val subOption1 = RegularActionItem(key = "subOption1", /* ... */)
val subOption2 = RegularActionItem(key = "subOption2", /* ... */)
val subOption3 = RegularActionItem(key = "subOption3", /* ... */)

val group = GroupActionItem(
    key = "myGroup",
    title = R.string.group_title,
    childOptions = listOf(subOption1, subOption2, subOption3)
)

Customisation

ActionMenu takes some parameters:

• maxNumberOfIcons Number of icons to show, including overflow menu icon (if needed);
• colors Optional color configuration.

ActionItems can be customised too:

• Use iconVector or iconDrawable to show an icon next to the item's title;
• Set showAsAction to change if an item will be shown as an icon or in the overflow menu.

Testing

Every menu item has a test tag attached to it which is a combination of a "ActionMenu" prefix and the item's key. Example test usage:

// Menu configuration:
val item = RegularActionItem(key = "myKey", /* ... */)

// Test:
composeTestRule.onNodeWithTag("ActionMenu#myKey").performClick()

There's a reserved key for the overflow icon: "ActionMenu#overflow".

Production example

Here's a production example to check out: the next update of my note taking app uses ComposeActionMenu. It's not released yet but when it is, this text will be updated.
