ScrollableTabRow

Composable Component

When a set of tabs cannot fit on screen, use scrollable tabs. Scrollable tabs can use longer text labels and a larger number of tabs. They are best used for browsing on touch interfaces.

Common

@Composable
fun ScrollableTabRow(
    selectedTabIndex: Int,
    modifier: Modifier = Modifier,
    backgroundColor: Color = MaterialTheme.colors.primarySurface,
    contentColor: Color = contentColorFor(backgroundColor),
    edgePadding: Dp = TabRowDefaults.ScrollableTabRowPadding,
    indicator: @Composable @UiComposable (tabPositions: List<TabPosition>) -> Unit =
        @Composable { tabPositions ->
            TabRowDefaults.Indicator(Modifier.tabIndicatorOffset(tabPositions[selectedTabIndex]))
        },
    divider: @Composable @UiComposable () -> Unit = @Composable { TabRowDefaults.Divider() },
    tabs: @Composable @UiComposable () -> Unit,
)

Parameters


selectedTabIndex	the index of the currently selected tab
modifier	optional `Modifier` for this ScrollableTabRow
backgroundColor	The background color for the ScrollableTabRow. Use `Color.Transparent` to have no color.
contentColor	The preferred content color provided by this ScrollableTabRow to its children. Defaults to either the matching content color for `backgroundColor`, or if `backgroundColor` is not a color from the theme, this will keep the same value set above this ScrollableTabRow.
edgePadding	the padding between the starting and ending edge of ScrollableTabRow, and the tabs inside the ScrollableTabRow. This padding helps inform the user that this tab row can be scrolled, unlike a `TabRow`.
indicator	the indicator that represents which tab is currently selected. By default this will be a `TabRowDefaults.Indicator`, using a `TabRowDefaults.tabIndicatorOffset` modifier to animate its position. Note that this indicator will be forced to fill up the entire ScrollableTabRow, so you should use `TabRowDefaults.tabIndicatorOffset` or similar to animate the actual drawn indicator inside this space, and provide an offset from the start.
divider	the divider displayed at the bottom of the ScrollableTabRow. This provides a layer of separation between the ScrollableTabRow and the content displayed underneath.
tabs	the tabs inside this ScrollableTabRow. Typically this will be multiple `Tab`s. Each element inside this lambda will be measured and placed evenly across the TabRow, each taking up equal space.
