所以我需要在 Jetpack Compose 中实现类似的形状
我正在尝试使用以下代码,但目前还没有成功:
fun clippedCardShape(clipRadius: Float = 30f): Shape {
return object : Shape {
override fun createOutline(
size: androidx.compose.ui.geometry.Size,
layoutDirection: LayoutDirection,
density: Density
): Outline {
val path = Path().apply {
// Top line
lineTo(size.width, 0f)
// Right side clipping
lineTo(size.width, size.height / 2 - clipRadius)
arcTo(
rect = Rect(
left = size.width - clipRadius * 2,
top = size.height / 2 - clipRadius,
right = size.width,
bottom = size.height / 2 + clipRadius
),
startAngleDegrees = 270f,
sweepAngleDegrees = -180f,
forceMoveTo = false
)
lineTo(size.width, size.height)
// Bottom line
lineTo(0f, size.height)
// Left side clipping
lineTo(0f, size.height / 2 + clipRadius)
arcTo(
rect = Rect(
left = 0f,
top = size.height / 2 - clipRadius,
right = clipRadius * 2,
bottom = size.height / 2 + clipRadius
),
startAngleDegrees = 90f,
sweepAngleDegrees = 180f,
forceMoveTo = false
)
lineTo(0f, 0f)
close()
}
return Outline.Generic(path)
}
}
}
代码尝试在中间添加剪辑,但它应该像示例图像一样几乎位于形状的顶部。
结果:
因此,我希望从知道如何处理该问题的人那里看到一个可行的示例,以便我可以学习它并弄清楚如何在不同情况下实现类似形状的逻辑和数学。
更新
取得了一些进展,但仍然存在问题:
val clipRadius = 20f // Radius of the left and right clips
val path = Path().apply {
// Move to the top-left corner
moveTo(0f, 0f)
// Top-left corner
lineTo(0f, 0f)
// Left clip arc
arcTo(
rect = Rect(
left = 0f,
top = (size.height / 2) - clipRadius,
right = clipRadius * 2,
bottom = (size.height / 2) + clipRadius
),
startAngleDegrees = 270f,
sweepAngleDegrees = 180f,
forceMoveTo = false
)
// Bottom-left corner
lineTo(0f, size.height)
// Bottom-left to bottom-right
lineTo(size.width, size.height)
// Right clip arc
arcTo(
rect = Rect(
left = size.width - (clipRadius * 2),
top = (size.height / 2) - clipRadius,
right = size.width,
bottom = (size.height / 2) + clipRadius
),
startAngleDegrees = 90f,
sweepAngleDegrees = 180f,
forceMoveTo = false
)
// Bottom-right corner
lineTo(size.width, 0f)
// Close the shape
close()
}
return Outline.Generic(path)
