android - 如何在 Jetpack Compose 中移动 slider 时移除拖动效果

Question

我想从 slider 刻度中删除拖动效果并移动它。
我不想在下图中出现这个浅紫色圆圈。

我知道 interactionSource Slider 中的参数组件，但我没有正确处理它以删除/禁用拖动效果。
这是我的实际代码:

var sliderWeight by remember { mutableStateOf(0f) }
Text(text = sliderWeight.toString())
Slider(value = sliderWeight, onValueChange = { sliderWeight = it }, interactionSource = remember { MutableInteractionSource() })

Answer 1

没有用于定义光晕颜色或光晕半径的参数，但您可以提供自定义 LocalRippleTheme 覆盖默认行为。
就像是:

CompositionLocalProvider(LocalRippleTheme provides NoRippleTheme) {
    Slider(
        value = sliderWeight,
        onValueChange = { sliderWeight = it },
    )
}

private object NoRippleTheme : RippleTheme {
    @Composable
    override fun defaultColor() = Color.Unspecified

    @Composable
    override fun rippleAlpha(): RippleAlpha = RippleAlpha(0.0f,0.0f,0.0f,0.0f)
}
