I have the following code:

public class AlertViewOnMap extends Activity {

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

    TextView busNumberTextView;
    TextView descriptionTextView;
    TextView alertTimeTextView;

    DateFormat dateFormat = new SimpleDateFormat("HH:mm");


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");
dateCreatedAtList = getIntent().getStringArrayListExtra("dateCreatedAtList");

    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
            .zoom(18.0f)                // Zoom
            .bearing(0)                // Orientation of the camera to east
            .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) {

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

            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())
                    ));
        }
    }

    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() {
            @Override
            public boolean onMarkerClick(Marker marker) {

                busNumberTextView.setText(marker.getSnippet());
                descriptionTextView.setText(marker.getTitle());
                alertTimeTextView.setText(dateCreatedAtList.get(marker.getId()));
                marker.showInfoWindow();
                return true;
            }
        };
    }    
}

My question is: I want to add custom data to be stored in my marker, such that when i click it, "alerTimeTextView" would get the marker creation hour, from "dateCreatedAtList"?

Try this way,hope,this will help you to solve your problem.

Define one HashMap with Marker as key and Alert as value and when you create new Marker to add on map at time add this Marker as key in HashMap and respective Alert data from alertsList,get specific Alert data from HashMap when particular Marker info window clicked.

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");
        dateCreatedAtList = getIntent().getStringArrayListExtra("dateCreatedAtList");

        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
                .zoom(18.0f)                // Zoom
                .bearing(0)                // Orientation of the camera to east
                .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() {
            @Override
            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;
            }
        };
    }
}
