Hi everyone, Good morning/afternoon, #compose #jetpack-compose #android

I have a dimen file where I have text sizes. I need to access in my Composable function. I tried with dimensionResource() but receiving error as "Type mismatch" Is there a way we can achieve in Jetpack compose.
Please find below code with error

<?xml version="1.0" encoding="utf-8"?>
<resources>

<dimen name="text_size_small">12sp</dimen>

</resources>


I tried to access as below:

val Typography.cguxTextFieldH1: TextStyle
@Composable
get() {
return TextStyle(
fontFamily = FontFamily(Font(R.font.roboto_regular)),
fontWeight = FontWeight(400),
fontStyle = FontStyle.Normal,
fontSize = dimensionResource(R.dimen.text_size_small)
)
}


Error Received:

Type mismatch.
Required:
TextUnit
Found:
Dp

fontSize uses SP, not DP, so font could be scaled without scaling UI

[B Chandrasaimohan]

Yes . But is there a way can we access SP from dimen.xml similar to dPs?

[gildor]

I think the only way is to get value and convert it to SP

[gildor]

it’s actually a good question

[B Chandrasaimohan]

I can try as below , but not sure whether its correct approach:

[B Chandrasaimohan]

dimensionResource(id = R.dimen.cgux_text_size_big).value.sp

[gildor]

should be fine, because dp resolved value in pixels from resources using current configuration, converted to dp and you just convert it back to sp

[gildor]

when you resolve it from resources you always get value in pixels, it doesn’t distinguish dimension points, though I agree that semantically it doesn’t look right, but result should be correct

[B Chandrasaimohan]

ok sure. Thanks Andrey . I will follow this approach and check how it renders on UI. Thanks for your suggestions 🙂

[gildor]

Just realised that never had this case in our code, specifically with SP

[B Chandrasaimohan]

Then how are you handling Textsizes in composables ? Are you directly providing as 16.sp or 5.sp like that instead of referring from dimen.xml ?
