RadioButton

Composable Component

The Wear Material RadioButton offers slots and a specific layout for an icon, a label and a secondaryLabel. The icon and secondaryLabel are optional. The items are laid out in a row with the optional icon at the start, a column containing the two label slots in the middle and the selection control at the end.

Android

public fun RadioButton(
    selected: Boolean,
    onSelect: () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    shape: Shape = RadioButtonDefaults.radioButtonShape,
    colors: RadioButtonColors = RadioButtonDefaults.radioButtonColors(),
    contentPadding: PaddingValues = RadioButtonDefaults.ContentPadding,
    interactionSource: MutableInteractionSource? = null,
    transformation: SurfaceTransformation? = null,
    icon: @Composable (BoxScope.() -> Unit)? = null,
    secondaryLabel: @Composable (RowScope.() -> Unit)? = null,
    label: @Composable RowScope.() -> Unit,
)

Parameters


selected	Boolean flag indicating whether this button is currently selected.
onSelect	Callback to be invoked when this button has been selected by clicking.
modifier	Modifier to be applied to the `RadioButton`.
enabled	Controls the enabled state of the button. When `false`, this button will not be clickable.
shape	Defines the button's shape. It is strongly recommended to use the default as this shape is a key characteristic of the Wear Material Theme.
colors	`RadioButtonColors` that will be used to resolve the background and content color for this button in different states.
contentPadding	The spacing values to apply internally between the container and the content.
interactionSource	an optional hoisted `MutableInteractionSource` for observing and emitting `Interaction`s for this radio button. You can use this to change the radio button's appearance or preview the radio button in different states. Note that if `null` is provided, interactions will still happen internally.
transformation	Transformation to be used when button appears inside a container that needs to dynamically change its content separately from the background.
icon	An optional slot for providing an icon to indicate the purpose of the button. The contents are expected to be center-aligned, both horizontally and vertically, and should be an icon of size 24.dp.
secondaryLabel	A slot for providing the button's secondary label. The contents are expected to be text which is "start" aligned.
label	A slot for providing the button's main label. The contents are expected to be text which is "start" aligned.
