Ripple with rounded corners Jetpack Compose

Question

In this answer I got wrong ripple animation. Do you know how to create ripple with rounded corners using Jetpack Compose?

With default ripple I have this:

Code:

Card(shape = RoundedCornerShape(30.dp),
        border = BorderStroke(width = 2.dp, color = buttonColor(LocalContext.current)),
        backgroundColor = backColor(LocalContext.current),
        modifier = Modifier
            .fillMaxWidth()
            .padding(10.dp)
            .clickable(
                interactionSource = remember { MutableInteractionSource() },
                indication = rememberRipple(radius = 30.dp)
            ) { show = !show }
    ) { ... } //Show is animation of other element.

//If I put radius of ripple 200 dp(it's a height of card) ripple works not normal.

Starting with M2 1.0.0-beta08 you can solve this issue using the onClick lambda parameter in the Card instead of the clickable modifier:

Card(
    shape = RoundedCornerShape(30.dp),
    modifier = Modifier
        .fillMaxWidth()
        .padding(10.dp),
    onClick = { show = !show }
){
  //card content
} 

If you need the clickable or the combinedClickable modifier you have to use the variant without the onClick parameter and to apply also the clip modifier to the Card using the same Card shape:

val shape = RoundedCornerShape(30.dp)

Card(
    shape = shape,
    modifier = Modifier
        //...height, width, padding
        .clip(shape)
        .combinedClickable(
            onLongClick =  { /** do something */ },
            onClick = { /** do something */ }
        )
){
   //card content
}

With M3 Card you can do the same.

Until 1.0.0-beta07 applying a .clickable modifier to the Card the ripples aren't clipped by the bounds of the layout.

As workaround you can apply the .clickable modifier to the content of the Card (for example a Box):

    Card(
        shape = RoundedCornerShape(30.dp),
        border = BorderStroke(width = 2.dp, color = Color.Blue),
        backgroundColor = Color.White,
        modifier = Modifier
            .fillMaxWidth()
            .padding(10.dp)

    ) {
        Box(Modifier
              .clickable(
                  onClick = { /* ...*/ }
              )
        ){
            Text("Text")
        }
    }

Answer 2

I've so far identified 2 options:

1. In addition to setting the shape, use .clip modifier to clip the Card using the same shape:

Card(
    shape = RoundedCornerShape(30.dp),
    modifier = Modifier
        .clip(RoundedCornerShape(30.dp))
        .clickable {
                //do something
        }
) {
    Box {
        Text("Text")
    }
}

The downside of this approach is that the elevation shadow gets clips as well, so your Card loses it's shadow.

2. Set the .clickable on the Card content composable:

 Card(
    shape = RoundedCornerShape(30.dp)
) {
    Box(
        modifier = Modifier.clickable {
                //do something
        }
    ) {
        Text("Text")
    }
}

Answer 3

I checked the sources of Card/Surface composables and found out that you need to have background and clip modifiers with the same shape. So for example the following Box has rounded corner shape and click ripple is cut with the same bounds:

val shape = RoundedCornerShape(16.dp)
Box(
    modifier = Modifier
        .background(
            color = Color.Yellow,
            shape = shape
        )
        .clip(shape)
        .clickable { onClick() },
) {
 // your content here
}

Answer 4

Hope this will grant you the easiest solution

Just add .clip(RoundedCornerShape(30.dp)) in the modifier parameter

Here is the full code :

Card(modifier = Modifier
    .padding(30.dp)
    .size(100.dp)
    .clip(RoundedCornerShape(30.dp))
    .clickable {
        // After clip //
    }) { }

Answer 5

using rememberRipple(bounded = false) will give a circular ripple effect around the clicked component. It can be used as ->

Modifier.clickable(
             indication = rememberRipple(bounded = false),
             interactionSource = remember {
                        MutableInteractionSource()
                    }
            ) { }
                

Answer 6

When you use long press or other gesture,you can use modifier.indication

val interactionSource = remember { MutableInteractionSource() }

Card(
    modifier = Modifier
      .padding(12.dp, 6.dp)
      .fillMaxWidth()
      .clip(RoundedCornerShape(12.dp))
      .indication(interactionSource, LocalIndication.current)
      .pointerInput(Unit) {
        detectTapGestures(
          onPress = { offset ->
            val press = PressInteraction.Press(offset)
            interactionSource.emit(press)
            tryAwaitRelease()
            interactionSource.emit(PressInteraction.Release(press))
          },
          onLongPress = {},
          onTap = {}
        )
      }
  )
