Functions

@Composable
fun Chip(
    onClick: () -> Unit,
    colors: ChipColors,
    border: ChipBorder,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    contentPadding: PaddingValues = ChipDefaults.ContentPadding,
    shape: Shape = MaterialTheme.shapes.large,
    interactionSource: MutableInteractionSource? = null,
    role: Role? = Role.Button,
    content: @Composable RowScope.() -> Unit
): Unit

Base level Wear Material Chip that offers a single slot to take any content.

Is used as the container for more opinionated Chip components that take specific content such as icons and labels.

The Chip is Stadium shaped and has a max height designed to take no more than two lines of text of Typography.button style. The Chip can have an icon or image horizontally parallel to the two lines of text. With localisation and/or large font sizes, the Chip height adjusts to accommodate the contents.

The Chip can have different styles with configurable content colors, background colors including gradients, these are provided by ChipColors implementations.

The recommended set of ChipColors styles can be obtained from ChipDefaults, e.g. ChipDefaults.primaryChipColors to get a color scheme for a primary Chip which by default will have a solid background of Colors.primary and content color of Colors.onPrimary.

Chips can be enabled or disabled. A disabled chip will not respond to click events.

For more information, see the Chips guide.

Parameters
onClick: () -> Unit

Will be called when the user clicks the chip

colors: ChipColors

ChipColors that will be used to resolve the background and content color for this chip in different states. See ChipDefaults.chipColors.

border: ChipBorder

ChipBorder that will be used to resolve the border for this chip in different states. See ChipDefaults.chipBorder.

modifier: Modifier = Modifier

Modifier to be applied to the chip

enabled: Boolean = true

Controls the enabled state of the chip. When false, this chip will not be clickable

contentPadding: PaddingValues = ChipDefaults.ContentPadding

The spacing values to apply internally between the container and the content

shape: Shape = MaterialTheme.shapes.large

Defines the chip's shape. It is strongly recommended to use the default as this shape is a key characteristic of the Wear Material Theme

interactionSource: MutableInteractionSource? = null

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this chip. You can use this to change the chip's appearance or preview the chip in different states. Note that if null is provided, interactions will still happen internally.

role: Role? = Role.Button

The type of user interface element. Accessibility services might use this to describe the element or do customizations

content: @Composable RowScope.() -> Unit

Slot for composable body content displayed on the Chip

@Composable
fun Chip(
    label: @Composable RowScope.() -> Unit,
    onClick: () -> Unit,
    modifier: Modifier = Modifier,
    secondaryLabel: (@Composable RowScope.() -> Unit)? = null,
    icon: (@Composable BoxScope.() -> Unit)? = null,
    colors: ChipColors = ChipDefaults.primaryChipColors(),
    enabled: Boolean = true,
    interactionSource: MutableInteractionSource? = null,
    contentPadding: PaddingValues = ChipDefaults.ContentPadding,
    shape: Shape = MaterialTheme.shapes.large,
    border: ChipBorder = ChipDefaults.chipBorder()
): Unit

Wear Material Chip that offers three slots and a specific layout for an icon, label and secondaryLabel. The icon and secondaryLabel are optional. The items are laid out with the icon, if provided, at the start of a row, with a column next containing the two label slots.

The Chip is Stadium shaped and has a max height designed to take no more than two lines of text of Typography.button style. If no secondary label is provided then the label can be two lines of text. The label and secondary label should be consistently aligned. With localisation and/or large font sizes, the Chip height adjusts to accommodate the contents.

If a icon is provided then the labels should be "start" aligned, e.g. left aligned in ltr so that the text starts next to the icon.

The Chip can have different styles with configurable content colors, background colors including gradients, these are provided by ChipColors implementations.

The recommended set of ChipColors styles can be obtained from ChipDefaults, e.g. ChipDefaults.primaryChipColors to get a color scheme for a primary Chip which by default will have a solid background of Colors.primary and content color of Colors.onPrimary.

Chips can be enabled or disabled. A disabled chip will not respond to click events.

Will be called when the user clicks the chip

modifier: Modifier = Modifier

Modifier to be applied to the chip

secondaryLabel: (@Composable RowScope.() -> Unit)? = null

icon: (@Composable BoxScope.() -> Unit)? = null

A slot for providing the chip's icon. The contents are expected to be a horizontally and vertically aligned icon of size ChipDefaults.IconSize or ChipDefaults.LargeIconSize. In order to correctly render when the Chip is not enabled the icon must set its alpha value to LocalContentAlpha.
