从Kotlin中的googlemaps获取相机缩放级别

import com.google.android.gms.maps.CameraUpdateFactory
import com.google.android.gms.maps.GoogleMap
import com.google.android.gms.maps.OnMapReadyCallback
import com.google.android.gms.maps.SupportMapFragment

class MapsFragment : Fragment(), OnMapReadyCallback {

    private lateinit var mMap: GoogleMap

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val rootView = inflater.inflate(R.layout.fragment_maps, container, false)

        val mapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment
        mapFragment.getMapAsync(this)

        return rootView
    }

    override fun onMapReady(googleMap: GoogleMap) {
        mMap = googleMap

        // 获取相机缩放级别
        val zoomLevel = mMap.cameraPosition.zoom

        // 在控制台打印相机缩放级别
        Log.d("MapsFragment", "相机缩放级别: $zoomLevel")
    }
}
