如何解决使标记带有自定义信息，以供单击时使用（Android，Google Maps v2）？

定义一个以 *

public class AlertVIEwOnMap extends Activity {

    //declarations
    ArrayList<String> dateCreatedAtList = new ArrayList<String>();

    TextVIEw busnumberTextVIEw;
    TextVIEw descriptiontextVIEw;
    TextVIEw alertTimeTextVIEw;

    DateFormat dateFormat = new SimpleDateFormat("HH:mm");
    private HashMap<Marker,Alert> markerDataMap;


    protected voID onCreate(Bundle savedInstanceStatE) {
        // Todo auto-generated method stub
        super.onCreate(savedInstanceStatE);
        this.setContentVIEw(com.fourBox.bocterapp.R.layout.details_design);

        busnumberTextVIEw = (TextVIEw) findVIEwByID(R.ID.textVIEwAlertBusnumber);
        descriptiontextVIEw = (TextVIEw) findVIEwByID(R.ID.textVIEwAlertDescription);
        alertTimeTextVIEw = (TextVIEw) findVIEwByID(R.ID.textVIEwAlertTimE);

        busnumber = geTintent().getIntextra("busnumber", 0);
        description = geTintent().getStringExtra("description");
        coordinatesLatitude =  geTintent().getDoubleExtra("coordinatesLatitude", 0);
        coordinatesLongitude = geTintent().getDoubleExtra("coordinatesLongitude", 0);

        alertTime.setTime(geTintent().getLongExtra("createdAt", 0));

        busnumberList = geTintent().getStringArrayListExtra("busnumberList");
        descriptionList = geTintent().getStringArrayListExtra("descriptionList");
        coordinatesLatitudeList =     geTintent().getStringArrayListExtra("coordinatesLatitudeList");
        coordinatesLongitudeList =     geTintent().getStringArrayListExtra("coordinatesLongitudeList");

        GoogleMap mMap;
        mMap = ((MapFragment)     getFragmentManager().findFragmentByID(com.fourBox.bocterapp.R.ID.mapFragment)).getMap();
        reunitealertListFromGetExtra();
        placeAllMarkersOnMap(mMap, alertsList);

        LatLng latLng = new LatLng(coordinatesLatitude, coordinatesLongitudE);

        Cameraposition cameraposition = new Cameraposition.builder()
                .target(latLng) // Center Set

                .tilt(30)                   // Tilt of the camera to 30 degrees
                .build();                   // Creates a Cameraposition from the builder
        mMap.animateCamera(CameraupdateFactory.newCameraposition(cameraposition));

        busnumberTextVIEw.setText(String.valueOf(busnumber));
        descriptiontextVIEw.setText(description);
        alertTimeTextVIEw.setText(String.valueOf(dateFormat.format(alertTimE)));
    }

    public voID placeAllMarkersOnMap(GoogleMap mMap, ArrayList<Alert> alertsList) {
        markerDataMap = new HashMap<Marker, Alert>();
        for(int i=0; i<alertsList.size(); i++) {
            markerDataMap.put(mMap.addMarker(new MarkerOptions()
                    .position(new     LatLng(alertsList.get(i).getCoordinates().getLatitude(),     alertsList.get(i).getCoordinates().getLongitude()))
                    .title(alertsList.get(i).getDescription())
                    .snippet(String.valueOf(alertsList.get(i).getBusnumber())
                    )),alertsList.get(i));

        }
    }

    public voID reunitealertListFromGetExtra() {

        for (int i =0; i<busnumberList.size(); i++) {

            Alert alert = new Alert();
            ParseGeoPoint parseGeoPoint = new ParseGeoPoint();

            parseGeoPoint.setLatitude(Double.valueOf(coordinatesLatitudeList.get(i)));
            parseGeoPoint.setLongitude(Double.valueOf(coordinatesLongitudeList.get(i)));

            alert.setBusnumber(Integer.valueOf(busnumberList.get(i)));
            alert.setDescription(descriptionList.get(i));
            alert.setCoordinates(parseGeoPoint);
            alert.setCreatedAt(new Date(Long.valueOf(dateCreatedAtList.get(i))));

            alertsList.add(alert);
        }
    }

    public GoogleMap.onMarkerClickListener geTinfoMarkerClickListener() {
        return new GoogleMap.onMarkerClickListener() {

            public Boolean onMarkerClick(Marker marker) {
                Alert alert = markerDataMap.get(marker);
                busnumberTextVIEw.setText(alert.getDescription());
                descriptiontextVIEw.setText(alert.getBusnumber());
                alertTimeTextVIEw.setText(dateCreatedAtList.get(alert.getID()));
                marker.showInfoWindow();
                return true;
            }
        };
    }
}

            alertsList.add(alert);
        }
    }

    public GoogleMap.onMarkerClickListener geTinfoMarkerClickListener() {
        return new GoogleMap.onMarkerClickListener() {
            @Override
