只需使用 aCanvas并繪制 2 個圓圈和 1 條線。
Canvas(Modifier.fillMaxSize()){
val radius = 64f //radius of circles
val strokeWidth = 20f
val lineHeight = 300f
val centerFirstCircle = Offset(100f, 100f)
drawCircle(
color = Color.Red,
radius = radius,
center = centerFirstCircle,
style = Stroke(width = strokeWidth)
)
//calculate the start and end of the vertical line
val xLine = centerFirstCircle.x
val yLine = centerFirstCircle.y radius strokeWidth/2
drawLine(
color = Red,
start = Offset(xLine, yLine),
end = Offset(xLine , yLine lineHeight),
strokeWidth = strokeWidth
)
//calculate the center of the second circle
val centerSecondCircle = Offset( centerFirstCircle.x,
centerFirstCircle.y (radius*2) lineHeight (strokeWidth/2 *2) )
drawCircle(
color = Color.Red,
radius = radius,
center = centerSecondCircle,
style = Stroke(width = strokeWidth)
)
}
