There is no ripple effect when I click on MyBox()
I've added MyTheme(){} to main @Composable screen but it doesn't work. Is something missing?
@Composable
private MyBox(onClickInvoked: () -> Unit) {
MyAppTheme(isSystemInDarkTheme()) {
Box(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight()
.clip(RoundedCornerShape(10.dp))
.background(MaterialTheme.colors.onBackground)
.clickable(onClick = { onClickInvoked.invoke() })
.padding(horizontal = 10.dp, vertical = 15.dp)
) {
Text(
text = "My text",
modifier = Modifier
.align(Alignment.CenterStart)
.padding(end = 95.dp)
.wrapContentWidth()
.wrapContentHeight(),
color = MaterialTheme.colors.primary
)
Image(
painter = painterResource(R.drawable.icon),
modifier = Modifier
.align(Alignment.CenterEnd)
.padding(end = 20.dp)
.size(60.dp)
)
}
}
}
With compose 1.0.5, I see the default indication
after set clickable
is LocalIndication.current
. And LocalIndication.current
is PlatformRipple
. Therefore, after you set clickable
to your Box
, it will have ripple effect.
In your case, I think the ripple effect won't display because your Box background is too dark (normally MaterialTheme.colors.onBackground
is black on Light theme)
I think you can change the ripple effect color to make it easy to see.
Surface(
onClick = { onClickInvoked.invoke() },
modifier = Modifier.fillMaxWidth(),
shape = RoundedCornerShape(10.dp),
color = MaterialTheme.colors.onBackground, // normally it is black on Light theme
indication = rememberRipple(color = Color.White) // color for your ripple, you can use other suitable MaterialTheme.colors for your case to support Light/Dark mode
) {
Box(modifier = Modifier.padding(horizontal = 10.dp, vertical = 15.dp)) {
// your Box content
...
}
}
There is a Modifier.indication
but after testing I see it not working with Modifier.clickable
so I use Surface
I don't really know if there is a problem with your theme. I try to pass the material theme, and the ripples will display normally
MaterialTheme() {
Box(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight()
.clip(RoundedCornerShape(10.dp))
.background(MaterialTheme.colors.secondary)
.clickable(onClick = { t = "My text" })
.padding(horizontal = 10.dp, vertical = 15.dp)
) {
Text(
text = t,
modifier = Modifier
.align(Alignment.CenterStart)
.padding(end = 95.dp)
.wrapContentWidth()
.wrapContentHeight(),
color = MaterialTheme.colors.primary
)
Image(
painter = painterResource(R.drawable.ic_launcher_foreground),
modifier = Modifier
.align(Alignment.CenterEnd)
.padding(end = 20.dp)
.size(60.dp),
contentDescription = ""
)
}
}
