Question

i’m trying to make a map in my application which the latitude and longitude from my database MySQL.

that’s my screenshot listview when click i want to show on map.

and here’s my activity :

public class Map_TokoBengkel extends MapActivity {
    private MapView mapView;
    private LocationManager locManager;
    private LocationListener locListener;
    Entity_BikeShopRepair entity;
    private ArrayList<Entity_BikeShopRepair> list_lokasi = new ArrayList<Entity_BikeShopRepair>();

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_shoprepair);

        final ActionBar actionBar = (ActionBar) findViewById(R.id.actionbar);
        actionBar.setTitle(getString(R.string.app_name));

        actionBar.setHomeAction(new IntentAction(this, new Intent(this,
                Home_Activity.class), R.drawable.home));

        initLokasi();
        initMap();
        initLocationManager();
    }

    /**
     * Initialize the map to the Data Location.
     */
    private void initLokasi() {
        list_lokasi.add(entity.getLat(), entity.getLng(), 1, entity.getShop_Name());
    }

    /**
     * Initialize the map to the LinearLayout.
     */
    private void initMap() {
        mapView = (MapView) findViewById(R.id.map_view);
        mapView.displayZoomControls(true);
        mapView.setBuiltInZoomControls(true);
        mapView.getController().setZoom(15);
    }

    /**
     * Initialize the location manager.
     */
    private void initLocationManager() {
        locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        locListener = new LocationListener() {
            // method ini akan dijalankan apabila koordinat GPS berubah
            public void onLocationChanged(Location newLocation) {
                tampilkanPosisikeMap(newLocation);
            }

            public void onProviderDisabled(String arg0) {
            }

            public void onProviderEnabled(String arg0) {
            }

            public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
            }
        };
        locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                1000, locListener);

    }

    /**
     * This method will be called when current position changed is submitted via
     * the GPS.
     * 
     * @param newLocation
     */
    protected void tampilkanPosisikeMap(Location newLocation) {
        List<Overlay> overlays = mapView.getOverlays();

        // first remove old overlay
        if (overlays.size() > 0) {
            for (Iterator iterator = overlays.iterator(); iterator.hasNext();) {
                iterator.next();
                iterator.remove();
            }
        }

        // transform the location to a geopoint
        GeoPoint geopoint = new GeoPoint(
                (int) (newLocation.getLatitude() * 1E6),

        GeoPoint myposition = geopoint;

        // initialize icon
        Drawable icon = getResources().getDrawable(R.drawable.marker);
        icon.setBounds(0, 0, icon.getIntrinsicWidth(),
                icon.getIntrinsicHeight());

        // create my overlay and show it
        MyItemizedOverlay overlay = new MyItemizedOverlay(icon, this);
        OverlayItem item = new OverlayItem(geopoint, "My Location", "Lat:"
                + locationA.getLatitude() + "\nLng:" + locationA.getLongitude());
        overlay.addItem(item);
        mapView.getOverlays().add(overlay);
        for (int i = 0; i < list_lokasi.size(); i++) {
            geopoint = new GeoPoint((int) (list_lokasi.get(i).lat * 1E6),
                    (int) (list_lokasi.get(i).lng * 1E6));
            locationB.setLatitude(geopoint.getLatitudeE6() / 1E6);
            locationB.setLongitude(geopoint.getLongitudeE6() / 1E6);

            double distance = locationA.distanceTo(locationB);

            if (list_lokasi.get(i).category == 1) {
                icon = getResources().getDrawable(R.drawable.bicycle_shop);
            } else if (list_lokasi.get(i).category == 2) {
                icon = getResources().getDrawable(R.drawable.bicycle_shop);
            } else if (list_lokasi.get(i).category == 3) {
                icon = getResources().getDrawable(R.drawable.bicycle_shop);
            }

            icon.setBounds(0, 0, icon.getIntrinsicWidth(),
                    icon.getIntrinsicHeight());
            overlay = new MyItemizedOverlay(icon, this);
            item = new OverlayItem(geopoint, list_lokasi.get(i).lokname, "Lat:"
                    + list_lokasi.get(i).lat + "\nLng:"
                    + list_lokasi.get(i).lng + "\n Jarak:" + distance + "m");
            overlay.addItem(item);
            mapView.getOverlays().add(overlay);
        }

        // move to location
        mapView.getController().animateTo(myposition);

        // redraw map
        mapView.postInvalidate();
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

but at that code there is something error in

private void initLokasi() {
    list_lokasi.add(entity.getLat(), entity.getLng(), 1, entity.getShop_Name());
} 

and the error message is:

The method add(int, Entity_BikeShopRepair) in the type ArrayList<Entity_BikeShopRepair> is not applicable for the arguments (double, double, int, String)`.

can somebody help me solved my problem?

Answer 1

The problem is right there in the error

The method add(int, Entity_BikeShopRepair) in the type
ArrayList is not applicable for the arguments
(double, double, int, String)

The compiler is telling you that it is expecting you to give it an int and an Entity_BikeShopRepair and instead you’re giving it four parameters so it doesn’t know what to do.

list_lokasi.add(entity.getLat(), entity.getLng(), 1, entity.getShop_Name()); 

It looks like you just need to do

list_lokasi.add(1, entity);

or, if you don’t care what position in the list the entity is added,

list_lokasi.add(entity);
