Buttons

Use a Button component for actions that are well understood by users and don’t need a text label. Buttons are distinguished from chips by their circular shape.

Anatomy

A. Content

Buttons have a single slot reserved for an icon or text. Choose an icon that is relevant to the action the button performs. You can use text with a maximum of three characters if an icon is unable to describe the relevant action. Consider the use of a Chip component if an icon can’t clearly describe the action

B. Container

Button containers are limited to a single solid color fill.

Toggle buttons

Toggle buttons enable users to toggle between two states.

Compact buttons

Compact buttons appear smaller but have a larger tappable area. The default tappable area is 48x48dp.

Hierarchy

High emphasis

High emphasis buttons are distinguished by their fill. They contain actions that are primary to the app. For high emphasis buttons use Primary or Secondary colors for the container and On Primary and On Secondary colors for the content. For more information see Wear Material Theming.

Medium emphasis

Medium emphasis buttons are distinguished by a less contrasting color fill. They contain actions that are less important than the primary actions. Use the Surface color for the container and the On Surface color for the content.

Low emphasis (icon only)

Low emphasis buttons are distinguished by having no fill. They are best suited for smaller areas on the watch face where a compact arrangement is needed. Use the On Surface colour for the content.

Sizes

Use buttons of different sizes to emphasize or de-emphasize actions.

Usage

Use standard buttons to enable the user to take a single action such as accepting or declining a call, or starting a timer.

Use toggle buttons to allow the user to turn an option on or off, such as selecting and deselecting days of the week or pausing and restarting a timer.
