Segmented button Stay organized with collections Save and categorize content based on your preferences.

Use a segmented button to let users choose from a set of options, side-by-side. There are two types of segmented buttons:

• Single-select button: Lets users choose one option.
• Multi-select button: Lets users choose between two and five items. For more complex choices, or more than five items, use chips.

API surface

Use the SingleChoiceSegmentedButtonRow and MultiChoiceSegmentedButtonRow layouts to create segmented buttons. These layouts position and size SegmentedButtons correctly, and share the following key parameters:

• space: Adjusts the overlap between the buttons.
• content: Contains the content of the segmented button row, which is typically a sequence of SegmentedButtons.

Create a single-select segmented button

This example shows how to create a single-select segmented button:

@Composable
fun SingleChoiceSegmentedButton(modifier: Modifier = Modifier) {
    var selectedIndex by remember { mutableIntStateOf(0) }
    val options = listOf("Day", "Month", "Week")

    SingleChoiceSegmentedButtonRow {
        options.forEachIndexed { index, label ->
            SegmentedButton(
                shape = SegmentedButtonDefaults.itemShape(
                    index = index,
                    count = options.size
                ),
                onClick = { selectedIndex = index },
                selected = index == selectedIndex,
                label = { Text(label) }
            )
        }
    }
}

Key points about the code

• Initializes a selectedIndex variable using remember and mutableIntStateOf to track the selected button index.
• Defines a list of options representing the button labels.
• SingleChoiceSegmentedButtonRow lets you select only one button.
• Creates a SegmentedButton for each option, inside the forEachIndexed loop:
  • shape defines the button's shape based on its index and the total count of options using SegmentedButtonDefaults.itemShape.
  • onClick updates selectedIndex with the clicked button's index.
  • selected sets the button's selection state based on selectedIndex.
  • label displays the button label using the Text composable.

Create a multi-select segmented button

This example shows how to create a multi-choice segmented button with icons that lets users select multiple options:

@Composable
fun MultiChoiceSegmentedButton(modifier: Modifier = Modifier) {
    val selectedOptions = remember {
        mutableStateListOf(false, false, false)
    }
    val options = listOf("Walk", "Ride", "Drive")

    MultiChoiceSegmentedButtonRow {
        options.forEachIndexed { index, label ->
            SegmentedButton(
                shape = SegmentedButtonDefaults.itemShape(
                    index = index,
                    count = options.size
                ),
                checked = selectedOptions[index],
                onCheckedChange = {
                    selectedOptions[index] = !selectedOptions[index]
                },
                icon = { SegmentedButtonDefaults.Icon(selectedOptions[index]) },
                label = {
                    when (label) {
                        "Walk" -> Icon(
                            imageVector =
                            Icons.AutoMirrored.Filled.DirectionsWalk,
                            contentDescription = "Directions Walk"
                        )
                        "Ride" -> Icon(
                            imageVector =
                            Icons.Default.DirectionsBus,
                            contentDescription = "Directions Bus"
                        )
                        "Drive" -> Icon(
                            imageVector =
                            Icons.Default.DirectionsCar,
                            contentDescription = "Directions Car"
                        )
                    }
                }
            )
        }
    }
}

Key points about the code

• The code initializes the selectedOptions variable using remember and mutableStateListOf. This tracks the selected state of each button.
• The code uses MultiChoiceSegmentedButtonRow to contain the buttons.
• Inside the forEachIndexed loop, the code creates a SegmentedButton for each option:
  • shape defines the button's shape based on its index and the total count of options.
  • checked sets the button's checked state based on the corresponding value in selectedOptions.
  • onCheckedChange toggles the selected state of the corresponding item in selectedOptions when the button is clicked.
  • icon displays an icon based on SegmentedButtonDefaults.Icon and the button's checked state.
  • label displays an icon corresponding to the label, using Icon composables with appropriate image vectors and content descriptions.
