如何将 Android 版 Google 地图中的可见区域放入更小的框中？

问：

我的屏幕上有一张带有路线的地图，还有一个抽屉。当我拉起抽屉以覆盖屏幕的 50%（近似数字）时，我希望我的地图缩小并向上移动，以便用户仍然可以看到路线。

我试过什么：

1. 移动地图，但我不知道缩放数：

      // Calculate the dimensions of the visible portion
        val visibleWidth = binding.mapView.width
        val visibleHeight = binding.mapView.height - binding.bottomSheet.root.height

        // Get the LatLng coordinates of the visible region
        val visibleTopLeft = googleMap.projection.fromScreenLocation(Point(0, 0));
        val visibleBottomRight = googleMap.projection.fromScreenLocation(Point(visibleWidth, visibleHeight))

        // Calculate the new camera position based on the visible region
        val newCenter = LatLng(
            (visibleTopLeft.latitude + visibleBottomRight.latitude) / 2,
            (visibleTopLeft.longitude + visibleBottomRight.longitude) / 2
        )
        val newZoomLevel = googleMap.cameraPosition.zoom //this should be something else

        // Create a new CameraPosition and update the camera
        val cameraPosition = CameraPosition.Builder()
            .target(newCenter)
            .zoom(newZoomLevel)
            .build();

        googleMap.moveCamera(CameraUpdateFactory.newCameraPosition(cameraPosition))

2. 再次添加路线坐标，并设置 CameraFactory.newLatLngBounds（） 宽度和高度以及填充：

        val builder = LatLngBounds.builder()
        coordinates.forEach { builder.include(it) }
        googleMap.moveCamera(
            CameraUpdateFactory.newLatLngBounds(
                builder.build(),
                binding.root.width.toPx(),
                calculatedHeight, //this doesn't work
                100.toPx()
            )
        )
