Functions

CompactChip

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

A compact Wear Material Chip that offers two slots and a specific layout for an icon and label. Both the icon and label are optional however it is expected that at least one will be provided.

The CompactChip is Stadium shaped and has a max height designed to take no more than one line of text of Typography.caption1 style and/or one icon. The default max height is ChipDefaults.CompactChipHeight. This includes a visible chip height of 32.dp and 8.dp of padding above and below the chip in order to meet accessibility guidelines that request a minimum of 48.dp height and width of tappable area.

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 items are laid out as follows.

  1. If a label is provided then the chip will be laid out with the optional icon at the start of a row followed by the label with a default max height of ChipDefaults.CompactChipHeight.

  2. If only an icon is provided it will be laid out vertically and horizontally centered with a default height of ChipDefaults.CompactChipHeight and the default width of ChipDefaults.IconOnlyCompactChipWidth

If neither icon nor label is provided then the chip will displayed like an icon only chip but with no contents and ChipColors.background() color.

The CompactChip 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.

Example of a CompactChip with icon and single line of label text:

import androidx.compose.foundation.layout.size
import androidx.compose.ui.Modifier
import androidx.compose.ui.res.painterResource
import androidx.compose.ui.text.style.TextOverflow
import androidx.wear.compose.material.Chip
import androidx.wear.compose.material.ChipDefaults
import androidx.wear.compose.material.CompactChip
import androidx.wear.compose.material.Icon
import androidx.wear.compose.material.Text

CompactChip(
    onClick = { /* Do something */ },
    enabled = true,
    // CompactChip label should be no more than 1 line of text
    label = { Text("Single line label", maxLines = 1, overflow = TextOverflow.Ellipsis) },
    icon = {
        Icon(
            painter = painterResource(id = R.drawable.ic_airplanemode_active_24px),
            contentDescription = "airplane",
            modifier = Modifier.size(ChipDefaults.SmallIconSize),
        )
    },
)

Example of a CompactChip with a label, note that the text is center aligned:

import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.ui.Modifier
import androidx.compose.ui.text.style.TextAlign
import androidx.compose.ui.text.style.TextOverflow
import androidx.wear.compose.material.Chip
import androidx.wear.compose.material.CompactChip
import androidx.wear.compose.material.Text

CompactChip(
    onClick = { /* Do something */ },
    enabled = true,
    // CompactChip label should be no more than 1 line of text
    label = {
        Text(
            text = "Single line label",
            maxLines = 1,
            overflow = TextOverflow.Ellipsis,
            textAlign = TextAlign.Center,
            modifier = Modifier.fillMaxWidth(),
        )
    },
)

Example of a CompactChip with an icon only, note that the recommended icon size is 24x24 when only an icon is displayed:

import androidx.compose.foundation.layout.size
import androidx.compose.ui.Modifier
import androidx.compose.ui.res.painterResource
import androidx.wear.compose.material.Chip
import androidx.wear.compose.material.ChipDefaults
import androidx.wear.compose.material.CompactChip
import androidx.wear.compose.material.Icon

CompactChip(
    onClick = { /* Do something */ },
    enabled = true,
    icon = {
        Icon(
            painter = painterResource(id = R.drawable.ic_airplanemode_active_24px),
            contentDescription = "airplane",
            modifier = Modifier.size(ChipDefaults.IconSize),
        )
    },
)

For more information, see the Chips guide.

Parameters
onClick: () -> Unit

Will be called when the user clicks the chip
modifier: Modifier = Modifier

Modifier to be applied to the chip
label: (@Composable RowScope.() -> Unit)? = null

A slot for providing the chip's main label. The contents are expected to be text which is "start" aligned if there is an icon preset and "center" aligned if not.
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.SmallIconSize when used with a label or ChipDefaults.IconSize when used as the only content in the CompactChip. In order to correctly render when the Chip is not enabled the icon must set its alpha value to LocalContentAlpha.
colors: ChipColors = ChipDefaults.primaryChipColors()

ChipColors that will be used to resolve the background and content color for this chip in different states. See ChipDefaults.chipColors. Defaults to ChipDefaults.primaryChipColors
enabled: Boolean = true

Controls the enabled state of the chip. When false, this chip will not be clickable
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.
contentPadding: PaddingValues = ChipDefaults.CompactChipContentPadding

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
border: ChipBorder = ChipDefaults.chipBorder()

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