android - Android kotlin 将 textview 片段添加到 Google Maps Marker

Question

当您单击标记 .title 时，结果应该是带有附加信息的 textview 片段。

我正在使用带有标记悉尼的普通谷歌地图片段的数据绑定。

package com.swedestops.mapss3

import androidx.fragment.app.Fragment

import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.navigation.Navigation



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
import com.google.android.gms.maps.model.LatLng
import com.google.android.gms.maps.model.MarkerOptions

class MapsFragment : Fragment() {

    private val callback = OnMapReadyCallback { googleMap ->
       
        val sydney = LatLng(-34.0, 151.0)
        googleMap.addMarker(MarkerOptions()
            .position(sydney)
            .title("Marker in Sydney"))
        googleMap.moveCamera(CameraUpdateFactory.newLatLng(sydney))

   
    }

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

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        val mapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?
        mapFragment?.getMapAsync(callback)
    }
}
