Click on marker -> getInfoContents not show my custom widget

Question

Android studio:

implementation 'com.google.android.gms:play-services-maps:17.0.0'

in my activity:

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

private lateinit var mMap: GoogleMap

 mMap.setInfoWindowAdapter(object : GoogleMap.InfoWindowAdapter {
            override fun getInfoWindow(marker: Marker): View? {
                return null
            }

            // Important! Not work with "androidx.constraintlayout.widget.ConstraintLayout"
            override fun getInfoContents(marker: Marker): View? {
                val markerLatLng = marker.position
                val selectGazStation =
                    gazStationsList.first { it.latitude == markerLatLng.latitude && it.longitude == markerLatLng.longitude }
                Debug.d(TAG, "getInfoContents: selectGazStation = $selectGazStation")
                val agentSummaryInfoWidget = AgentSummaryInfoWidget(application, selectGazStation)
                return agentSummaryInfoWidget
            }
        })
    }

Here my custom widget AgentSummaryInfoWidget

class AgentSummaryInfoWidget(context: Context, selectGazStation: GazStation) :
    LinearLayout(context) {

    init {
        init(context, selectGazStation)
    }

    companion object {

        private val TAG = AgentSummaryInfoWidget::class.java.name
    }

    private fun init(context: Context, selectGazStation: GazStation) {
        val mapMarkerInfoContentLayoutBinding =
            MapMarkerInfoContentLayoutBinding.inflate(LayoutInflater.from(context));
        mapMarkerInfoContentLayoutBinding.addressValueTextView.setText(selectGazStation.address)
        var workingHours = "24/24"
        if (!selectGazStation.workingHours?.contains("NON-STOP", true)!!) {
            workingHours = selectGazStation.workingHours!!
        }
        mapMarkerInfoContentLayoutBinding.workingHoursValueTextView.setText(workingHours)
        mapMarkerInfoContentLayoutBinding.phoneValueTextView.setText(selectGazStation.phone)
    }
}

Here xml map_marker_info_content_layout:

Answer 1

You cannot float custom view directly on the markers, you can achieve by using custom markers (location icon with above your custom layout both included) and use this layout on the map and write onclick listeners to show and hide
