In Jetpack Compose Glimmer, a Button is an interactive component that's optimized for display glasses input, offering clear visual feedback through its states to guide user actions.

Buttons are built on the Jetpack Compose Glimmer surface system, which automatically handles physical properties like borders and depth.

The standard button contains a text label and optional icons. You can use it for primary or secondary actions. There are also specialized buttons, such as icon buttons and toggle buttons, which are defined as separate components in Jetpack Compose Glimmer.

States

Buttons in Jetpack Compose Glimmer change their appearance to communicate their state.

  • Enabled: The default state for an interactive button.
  • Focused: When focused, the button applies a GlimmerTheme.depthEffectLevels.level1 and a focused border highlight.
  • Pressed: When activated, a semi-transparent white overlay is applied to the surface.
  • Disabled: The button doesn't respond to input and its visual appearance is adjusted.

Button defaults

The following defaults apply to standard buttons:

  • By default, buttons use GlimmerTheme.typography.bodySmall. Make sure that text within buttons is concise and clearly describes the action.
  • The default shape for a button is GlimmerTheme.shapes.large. This consistent rounding helps users identify buttons across the display glasses interface.

Example: Button with text

The following code creates a standard button with text:

@Composable
fun ButtonSample() {
    Button(onClick = {}) { Text("Send") }
}

Example: Buttons with leading and trailing icons

You can also add icons to the start (using leadingIcon) or end (using trailingIcon) of the text to provide additional context.

The following code creates a button with a leading icon:

@Composable
fun ButtonWithLeadingIconSample() {
    Button(onClick = {}, leadingIcon = { Icon(FavoriteIcon, "Localized description") }) {
        Text("Send")
    }
}
