I have a Jetpack Compose Text() element that I'd like to outline in black like so .
Anyone know how to do this?
I've tried using the border() modifier, but that just adds a border around the rectangular area containing the text. I've also tried overlaying two text elements, but that doesn't quite work either.
The 1.4.0-alpha01
introduced a DrawStyle
parameter to TextStyle
function that enables drawing outlined text.
You can use something like:
Text(
text = "Sample",
style = TextStyle.Default.copy(
fontSize = 64.sp,
drawStyle = Stroke(
miter = 10f,
width = 5f,
join = StrokeJoin.Round
)
)
)
Before 1.4.0-alpha01
you can use a Canvas
and the drawIntoCanvas
function.
Something like:
Canvas(
modifier = Modifier.fillMaxSize(),
onDraw = {
drawIntoCanvas {
it.nativeCanvas.drawText(
"Sample",
0f,
120.dp.toPx(),
textPaintStroke
)
it.nativeCanvas.drawText(
"Sample",
0f,
120.dp.toPx(),
textPaint
)
}
}
)
with these Paint
:
val textPaintStroke = Paint().asFrameworkPaint().apply {
isAntiAlias = true
style = android.graphics.Paint.Style.STROKE
textSize = 64f
color = android.graphics.Color.BLACK
strokeWidth = 12f
strokeMiter= 10f
strokeJoin = android.graphics.Paint.Join.ROUND
}
val textPaint = Paint().asFrameworkPaint().apply {
isAntiAlias = true
style = android.graphics.Paint.Style.FILL
textSize = 64f
color = android.graphics.Color.WHITE
}
