Base level Wear Material3 FilledTonalButton that offers a single slot to take any content. Used as the container for more opinionated FilledTonalButton components that take specific content such as icons and labels.

The FilledTonalButton is Stadium-shaped by default and has a max height designed to take no more than two lines of text of Typography.labelMedium style. With localisation and/or large font sizes, the text can extend to a maximum of 3 lines in which case, the FilledTonalButton height adjusts to accommodate the contents. The FilledTonalButton can have an icon or image horizontally parallel to the two lines of text.

FilledTonalButton takes the ButtonDefaults.filledTonalButtonColors color scheme by default, with muted background, contrasting content color and no border. This is a medium-emphasis button for important actions that don't distract from other onscreen elements, such as final or unblocking actions in a flow with less emphasis than Button.

Other recommended buttons with ButtonColors for different levels of emphasis are: Button which defaults to ButtonDefaults.buttonColors, OutlinedButton which defaults to ButtonDefaults.outlinedButtonColors and ChildButton which defaults to ButtonDefaults.childButtonColors. For a background image, see the overload of Button with a containerPainter parameter.

FilledTonalButton can be enabled or disabled. A disabled button will not respond to click events.

Example of a FilledTonalButton:

import androidx.compose.ui.semantics.onClick
import androidx.wear.compose.material3.Button
import androidx.wear.compose.material3.FilledTonalButton
import androidx.wear.compose.material3.Text

FilledTonalButton(
    onClick = { /* Do something */ },
    label = { Text("Filled Tonal Button") },
    modifier = modifier,
)

Parameters
onClick: () -> Unit	Will be called when the user clicks the button
modifier: Modifier = Modifier	Modifier to be applied to the button
onLongClick: (() -> Unit)? = null	Called when this button is long clicked (long-pressed). When this callback is set, onLongClickLabel should be set as well.
onLongClickLabel: String? = null	Semantic / accessibility label for the onLongClick action.
enabled: Boolean = true	Controls the enabled state of the button. When false, this button will not be clickable
shape: Shape = ButtonDefaults.shape	Defines the button's shape. It is strongly recommended to use the default as this shape is a key characteristic of the Wear Material3 Theme
colors: ButtonColors = ButtonDefaults.filledTonalButtonColors()	ButtonColors that will be used to resolve the background and content color for this button in different states. See ButtonDefaults.filledTonalButtonColors.
border: BorderStroke? = null	Optional BorderStroke that will be used to resolve the border for this button in different states.
contentPadding: PaddingValues = ButtonDefaults.ContentPadding	The spacing values to apply internally between the container and the content
interactionSource: MutableInteractionSource? = null	an optional hoisted MutableInteractionSource for observing and emitting Interactions for this button. You can use this to change the button's appearance or preview the button in different states. Note that if null is provided, interactions will still happen internally.
transformation: SurfaceTransformation? = null	Transformation to be used when button appears inside a container that needs to dynamically change its content separately from the background.
content: @Composable RowScope.() -> Unit	Slot for composable body content displayed on the Button

Wear Material3 FilledTonalButton 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 FilledTonalButton is stadium-shaped by default and its standard height is designed to take 2 lines of text of Typography.labelMedium style - either a two-line label or both a single line label and a secondary label. With localisation and/or large font sizes, the FilledTonalButton height adjusts to accommodate the contents. The label and secondary label should be consistently aligned.

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.

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.

FilledTonalButton takes the ButtonDefaults.filledTonalButtonColors color scheme by default, with muted background, contrasting content color and no border. This is a medium-emphasis button for important actions that don't distract from other onscreen elements, such as final or unblocking actions in a flow with less emphasis than Button.

Other recommended buttons with ButtonColors for different levels of emphasis are: Button which defaults to ButtonDefaults.buttonColors, OutlinedButton which defaults to ButtonDefaults.outlinedButtonColors and ChildButton which defaults to ButtonDefaults.childButtonColors. For a background image, see the overload of Button with a containerPainter parameter.

FilledTonalButton can be enabled or disabled. A disabled button will not respond to click events.
