我遇到以下问题：我在 Google 地图上有多个标记。我已经使用一个 For 循环来完成此操作，该循环遍历我的对象数组并为每个对象添加一个标记。标记显示标题和地址。但现在我需要制作可点击的 InfoWindow（或只是可点击的标记），它将显示一个包含附加信息（描述）的 AlertDialog。但我无法让它工作。或者，数据不需要显示在 AlertDialog 中，我也可以显示在 TextView 中。

这是显示标记的部分代码（这是一个 FragmentActivity）：

...

Double longitude, latitude;
static LatLng coordinates;
GoogleMap supportMap;
String title, address;
BitmapDescriptor bdf;
ArrayList<GasStations> listGas = new ArrayList<GasStations>();

SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    supportMap = fm.getMap();
...

if (listGas != null) {
        for (int i = 0; i < listGas.size(); i++) {
            longitude = listGas.get(i).getLongitude();
            latitude = listGas.get(i).getLatitude();
            naslov = listGas.get(i).getTitle();
            adresa = listGas.get(i).getAddress() + " "
                    + listGas.get(i).getLocation();
            koordinate = new LatLng(latitude, longitude);

            supportMap.addMarker(new MarkerOptions().position(koordinate)
                    .title(title).snippet(address).icon(bdf));
            supportMap.moveCamera(CameraUpdateFactory.newLatLngZoom(
                    coordinates, 10));
        }
    }

标记显示得很好，它们的 InfoWindows 显示正确的数据。但现在我想根据单击的 InfoWindow 显示其他信息。如果这不能通过 InfoWindow 完成，是否可以通过单击特定标记来完成？

您可以创建自定义信息窗口

GoogleMap googleMap;

    Map.setInfoWindowAdapter(new InfoWindowAdapter() {


        @Override
        public View getInfoWindow(Marker arg0) {
            return null;
        }


        @Override
        public View getInfoContents(Marker arg0) {

            // Getting view from the layout file custom_window
            View v = getLayoutInflater().inflate(R.layout.custom_window, null);

            // Getting the position from the marker
            LatLng latLng = arg0.getPosition();


            TextView tvLat = (TextView) v.findViewById(R.id.lat);


            TextView tvLng = (TextView) v.findViewById(R.id.lng);

            tvLat.setText("Lat:" + latLng.latitude);


            return v;

        }
    });
