Hey guys I am using RoundedCornerShape(4.dp)
to my Surface
which looks fine. When I tried to click on the item it not showing me 4dp
corner in Surface. I tried this stack overflow 1 and stack overflow 2 but nothing works.
binding.itemComposable.setContent {
Column(modifier = Modifier.fillMaxSize(), verticalArrangement = Arrangement.spacedBy(12.dp)) {
val options = getOptions()
options.forEachIndexed { _, optionText ->
val interactionSource = remember { MutableInteractionSource() }
val isPressed by interactionSource.collectIsPressedAsState()
val backgroundColor = if (isPressed) DuckEggBlue else OffWhite
val textColor = if (isPressed) TealBlue else Slate
val borderWidth = if (isPressed) 1.dp else 0.dp
val borderColor = if (isPressed) Aqua else OffWhite
val clickable = Modifier.clickable(
interactionSource = interactionSource,
indication = rememberRipple(true)
) {
println("Item Click")
}
Surface(
modifier = Modifier
.then(clickable)
.border(borderWidth, borderColor),
shape = RoundedCornerShape(4.dp)
) {
Text(
modifier = Modifier
.fillMaxWidth()
.background(backgroundColor)
.padding(16.dp),
text = optionText,
style = Typography.h3,
fontWeight = FontWeight.Medium,
color = textColor
)
}
}
}
}
Without click on item corner is 4 dp
When I click it's not changing corner
Create a variable for shape
val shape = RoundedCornerShape(4.dp)
Use it in Modifier.clip()
and Modifier.border()
like this,
Surface(
modifier = Modifier
.clip(shape)
.border(
width = borderWidth,
color = borderColor,
shape = shape,
)
.then(clickable),
// shape = shape,
)
shape
in border()
specifies the shape of the border which by default is RectangleShape
. Hence, you are seeing the rectangle border.
shape
in clip()
changes the shape of the composable before the click action is added. This is to make the ripple effect appear only on the given shape.
Note : Order of modifiers are important.
The shape
in the Surface
may not be needed after these changes.
If youre using Surface to wrapping the content, try to add a container inside the content for example Box or Column. Then use your Surface only as a shape mask, the background and other content will be flexible as you want.
This is the example
Surface(
modifier = Modifier
.then(clickable)
.border(borderWidth, borderColor),
shape = RoundedCornerShape(4.dp)
) {
Box(modifier = Modifier
.fillMaxWidth()
.fillMaxHeight()
.background(Color.Green)){
Text(
modifier = Modifier
.fillMaxWidth()
.padding(16.dp),
text = optionText,
style = Typography.h3,
fontWeight = FontWeight.Medium,
color = textColor
)
}
}
If you want to handle the click on a Surface
you have to use the function that accepts an onClick()
:
Surface(
onClick = {},
shape = RoundedCornerShape(4.dp),
border = BorderStroke(borderWidth,borderColor),
interactionSource = interactionSource
)
