如何解决 setOnPlaceSelectedListener 没有工作？

Question

我想使用谷歌地图创建两点的方向。 如果设置了源点，我想在 Logcat 中看到 aaaaabbbbb 消息。 但我看不到它。

有人可以告诉我吗？

    // Initialize the AutocompleteSupportFragment
    val autoCompleteFragment_s = supportFragmentManager.findFragmentById(R.id.autocomplete_fragment_source) as AutocompleteSupportFragment
    val autoCompleteFragment_d = supportFragmentManager.findFragmentById(R.id.autocomplete_fragment_destination) as AutocompleteSupportFragment

    // Specify the types of place data to return
    autoCompleteFragment_s.setPlaceFields(mutableListOf(Place.Field.ID, Place.Field.NAME))
    autoCompleteFragment_d.setPlaceFields(mutableListOf(Place.Field.ID, Place.Field.NAME))


    Log.i(javaClass.simpleName,"aaaaa")
    // Set up a PlaceSelectionListener to handle the response.
    autoCompleteFragment_s.setOnPlaceSelectedListener(object: PlaceSelectionListener {

        override fun onPlaceSelected(place: Place){

            Log.i(javaClass.simpleName, "aaaaabbbbb")
            Log.i(javaClass.simpleName, "Place: " + place.getName() + ", " + place.getId())
            val latLngDest = LatLng(10.311794, 123.915863)
            googleMap!!.addMarker(MarkerOptions().position(latLngDest).title("Ehime City"))

        }

        override fun onError(status: Status) {
            Log.i(javaClass.simpleName, "aaaaabbbbb")
            Log.i(javaClass.simpleName, "An error occurred: " + status)
        }
    })

使用此方法将地图缩放到该位置：

public void animateMapCamera(LatLng point, int zoom) {
    if (googleMap != null) {
        CameraUpdate cu = CameraUpdateFactory.newLatLngZoom(point, zoom);
        googleMap.animateCamera(cu);
    }
}



    override fun onPlaceSelected(place: Place){

        Log.i(javaClass.simpleName, "aaaaabbbbb")
        Log.i(javaClass.simpleName, "Place: " + place.getName() + ", " + place.getId())
        val latLngDest = LatLng(10.311794, 123.915863)
        googleMap!!.addMarker(MarkerOptions().position(latLngDest).title("Ehime City"))


            animateMapCamera(latLngDest, 17);

    }
