Modify ripple color of IconButton in Jetpack Compose

I don't know if you found a way to make it work for the whole app but I found a way to do so. So I'm posting this incase someone else has a similar issue.

You can set the custom RippleTheme object as described by Gabriele Mariotti's answer then you can pass the CompositionLocalProvider() as content in MaterialTheme. The content from the app's theme can then be set as content for CompositionalLocalProvider().

Take a look here:

private object JetNewsRippleTheme : RippleTheme {
    // Here you should return the ripple color you want
    // and not use the defaultRippleColor extension on RippleTheme.
    // Using that will override the ripple color set in DarkMode
    // or when you set light parameter to false
    @Composable
    override fun defaultColor(): Color = MaterialTheme.colors.primary

    @Composable
    override fun rippleAlpha(): RippleAlpha = RippleTheme.defaultRippleAlpha(
        Color.Black,
        lightTheme = !isSystemInDarkTheme()
    )
}

Then for your app theme it should be:

@Composable
fun JetNewsTheme(
    darkTheme: Boolean = isSystemInDarkTheme(),
    content: @Composable () -> Unit
) {
    MaterialTheme(
        colors = if (darkTheme) DarkColors else LightColors,
        typography = JetNewsTypography,
        shapes = JetNewsShapes
    ) {
        CompositionLocalProvider(
            LocalRippleTheme provides JetNewsRippleTheme,
            content = content
        )
    }
}

This method should work for the whole app unless you explicitly set another RippleTheme directly to Composables below the AppTheme hierarchy. And it doesn't conflict with other types of ComposableLocalProvider values you may set directly to your other Composables.

Currently (1.0.0) your code doesn't work since the Ripple is implemented in a .clickable modifier defined inside the IconButton.

The appearance of the Ripples is based on a RippleTheme and you can define a custom RippleTheme and apply to your composable with the LocalRippleTheme.

Something like:

private object RippleCustomTheme: RippleTheme {

    //Your custom implementation...
    @Composable
    override fun defaultColor() =
        RippleTheme.defaultRippleColor(
            Color.Red, 
            lightTheme = true
        )

    @Composable
    override fun rippleAlpha(): RippleAlpha =
        RippleTheme.defaultRippleAlpha(
            Color.Black,
            lightTheme = true
        )
}

and:

CompositionLocalProvider(LocalRippleTheme provides  RippleCustomTheme) {
    IconButton(
        onClick = { },
    ) {
        Icon(Icons.Filled.Add, "")
    }
}

It's a bit late, but maybe this code will help someone.

To make your code work you need to apply interactionSource to the button itself too.

You can change the color locally in this way. It is important to apply height after calling the indication in order to keep the correct button and ripple dimensions.

Additionally, you need to apply a radius of any size in order to contain the radius inside of the button's shape (this seems to be a bug in Compose 1.2.0-rc03.

val interactionSource = remember { MutableInteractionSource() }
val rippleColor = Color.RED
val shape = RoundedCornerShape(size = 16.dp)

Button(
    modifier = Modifier
        .clip(shape = shape)
        .indication(
            interactionSource = interactionSource,
            indication = rememberRipple(
                color = rippleColor,
                radius = 8.dp
            )
        )
        .height(height = 40.dp),
    shape = shape,
    interactionSource = interactionSource,
)
