I am using Canvas Api to draw something. I want to draw line with rounded corner. Line is draw without any problem. But I cannot figure out which attribute for corner radius.

我在用帆布阿皮画东西。我想画圆角的线。划线没有任何问题。但我想不出拐角半径的属性是什么。


val boxSize = 30.dp

Box(modifier = Modifier
.background(Color.LightGray)
.height(height = boxSize)
) {
Canvas(
modifier = Modifier
.fillMaxWidth()
) {
val canvasWidth = size.width
drawLine(
start = Offset(x = 0f, y = (boxSize / 2).toPx()),
end = Offset(x = canvasWidth, y = (boxSize / 2).toPx()),
color = Color.Black,
strokeWidth = 8.dp.toPx()
)

}
}

My view is simple without corner radius.

我的观点很简单,没有拐角半径。

I want my Black line to be corner for each side with specific radius.

我希望我的黑线是角落的每一边与特定的半径。

You need to add the cap argument to drawLine and set it to StrokeCap.Round.

您需要将上限参数添加到DrawLine,并将其设置为StrokeCap.round。


 drawLine(
start = Offset(x = 0f, y = (boxSize / 2).toPx()),
end = Offset(x = canvasWidth, y = (boxSize / 2).toPx()),
color = Color.Black,
strokeWidth = 8.dp.toPx(),
cap = StrokeCap.Round, //add this line for rounded edges
)


Try this

尝尝这个


 Box(
modifier = Modifier.padding(top = 4.dp, bottom = 4.dp).width(40.dp).height(3.dp).clip(shape = RoundedCornerShape(size = 5.dp)).background(Color.Red)
)

How can I specific the radius of cap?

我怎样才能确定盖子的半径呢?

@VivekModi in this case you can't. It is based on the strokeWidth of the line.

@VivekModi在本例中不能。它基于行的strokeWidth。
