'How to convert TextUnit to Dp in Jetpack Compose?
I know the difference between them. I want to calculate the text height base on lineHeight. The value of lineHeight is in TextUnit so I want to convert it into Dp.
Solution 1:[1]
You need to grab the current Density from the LocalDensity—so this will only work in composition, within a @Composable function—and use that to convert to Dp:
val lineHeightSp: TextUnit = 12.sp
val lineHeightDp: Dp = with(LocalDensity.current) {
lineHeightSp.toDp()
}
Solution 2:[2]
private fun Int.textDp(density: Density): TextUnit = with(density) {
[email protected]()
}
val Int.textDp: TextUnit
@Composable get() = this.textDp(density = LocalDensity.current)
Solution 3:[3]
I'm using these global functions for this:
functions:
@Composable
fun Float.dp() = with(LocalDensity.current) { Dp(this@dp).toSp() }
@Composable
fun Int.dp() = with(LocalDensity.current) { Dp([email protected]()).toSp() }
usage:
Text(
text = lorem(2),
color = Color.Red, maxLines = 1000, fontSize = 20f.dp()
)

To convert Dp to Sp TextUnit use this extension from @yong wei's answer
@Composable
fun Dp.textSp() = with(LocalDensity.current) {
[email protected]()
}
val Dp.textSp: TextUnit
@Composable get() = with(LocalDensity.current) {
[email protected]()
}
Solution 5:[5]
You can:
Text(fontSize = 20.dpTextUnit,
text = "good good")
val Int.dpTextUnit: TextUnit
@Composable
get() = with(LocalDensity.current) { [email protected]() }
