Android Material3 滑块更改最后一个刻度线的颜色？

Question

Slider(
    value = bankloanamounttopay,
    onValueChange = { newvalue -> bankloanamounttopay = newvalue },
    valueRange = 0f..maxbankloanpayoffamount(),
    steps = numbankslidersteps(),
    colors = SliderDefaults.colors().copy(
        thumbColor = moneyred(),
        activeTrackColor = moneyred(),

        activeTickColor = Color.Transparent,
        inactiveTickColor = Color.Transparent,
    )
)

我知道我可以更改内部刻度线的颜色，但最终的刻度线似乎使用与

activeTrackColor

相同的颜色。有什么方法可以独立于

activeTrackColor

控制最后一个刻度线的颜色吗？

Answer 1

您可以覆盖

track

参数并使用默认的

SliderDefaults.Track

，但覆盖

drawStopIndicator

和

drawTick

参数：

val colors = SliderDefaults.colors().copy(
  thumbColor = moneyred(),
  activeTrackColor = moneyred(),
)
Slider(
    value = bankloanamounttopay,
    onValueChange = { newvalue -> bankloanamounttopay = newvalue },
    valueRange = 0f..maxbankloanpayoffamount(),
    steps = numbankslidersteps(),
    colors = colors,
    track = { state ->
      SliderDefaults.Track(
        sliderState = state,
        colors = colors,
        drawStopIndicator = null,
        drawTick = { _, _ -> },
      )
    }
)
