使用Modifier.clickable或PointerEventScope.detectTapGestures，您无法将手势传播到后代或父代，因为它们调用PointeEventChange.consume()，您可以在Jetpack Compose中查看有关手势和手势传播的答案。但在你的情况下，它看起来像你试图传播的事件，这是不可能的，和一个坏的设计，在我看来。
对于任何想要将手势传递给父母而不是兄弟姐妹的人，您可以使用awaitEachGesture轻松编写自定义的上下检测手势。

        .border(2.dp, Color.Red)
        .pointerInput(Unit) {
//            detectTapGestures {
//                Toast.makeText(context, "Parent tapped", Toast.LENGTH_SHORT).show()

            awaitEachGesture {
                val down: PointerInputChange = awaitFirstDown()
                val up: PointerInputChange? = waitForUpOrCancellation()
                Toast.makeText(context, "Parent tapped", Toast.LENGTH_SHORT).show()
            }
        }
    ) {
        Box(modifier = Modifier
            .background(Color.Red)
            .fillMaxSize()
            .zIndex(1f)
            .pointerInput(Unit) {
//                detectTapGestures {
//                    Toast.makeText(context, "Box1 tapped", Toast.LENGTH_SHORT).show()
//                }
                awaitEachGesture {
                    val down: PointerInputChange = awaitFirstDown()
                    val up: PointerInputChange? = waitForUpOrCancellation()
                    Toast.makeText(context, "Box1 tapped", Toast.LENGTH_SHORT).show()
                }
            }
        )
        Box(modifier = Modifier
            .background(Color.Black.copy(alpha = .5f))
            .fillMaxSize()
            .zIndex(2f)
            .pointerInput(Unit) {
//                detectTapGestures {
//                    Toast.makeText(context, "Box2 tapped", Toast.LENGTH_SHORT).show()
//                }
                awaitEachGesture {
                    val down: PointerInputChange = awaitFirstDown()
                    val up: PointerInputChange? = waitForUpOrCancellation()
                    Toast.makeText(context, "Box2 tapped", Toast.LENGTH_SHORT).show()
                }
            }
        )
    }
}

根据Box1和Box2的zIndex，您将看到该事件将为zIndex较大的一个触发，如果两个都为零（默认为零），则将为第二个Box触发，然后传播到父级。您可以通过使用这些PointerInputChange中的任何一个来选择性地更改它。
在OP情况下，不需要第二个盒子。带有圆形剪辑的黑色透明层可以使用Modifier.drawWithContent绘制，并基于触摸位置触发该层或任何组件中的单击事件。
你可以看到，当点击手势被消耗时，除非你消耗手势，否则手势会被传播。
