android - ItemisedOverlay Android を使用した複数のマーカー

Question

私のアプリケーションでは、Web サービスから複数の緯度と経度を取得しています。現時点では、以下のコードを使用してグール マップに 1 つの座標のみを表示できます。

public class CustomMap extends MapActivity {

    MapView mapView;
    List<Overlay> mapOverlays;
    Drawable drawable;
    Drawable drawable2;
    CustomItemizedOverlay<CustomOverlayItem> itemizedOverlay2;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gmap);
        //setContentView(LayoutInflater.from(getParent()).inflate(R.layout.main_ou, null));

        mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);
        mapOverlays = mapView.getOverlays();

        // second overlay
        drawable2 = getResources().getDrawable(R.drawable.red);
        itemizedOverlay2 = new CustomItemizedOverlay<CustomOverlayItem>(drawable2, mapView);
        GeoPoint point3 =  new GeoPoint((int)(-10.224609*1E6),(int)(17.506044*1E6));
        CustomOverlayItem overlayItem3 = new CustomOverlayItem(point3, "Title", 
        "Cliquez here", null);

        itemizedOverlay2.addOverlay(overlayItem3);
        //itemizedOverlay2.onTap(0);

        mapOverlays.add(itemizedOverlay2);

        final MapController mc = mapView.getController();
        mc.animateTo(point3);
        mc.setZoom(16);

    }


    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }




}

今、私は配列を使用して動的に地図に緯度と経度を設定したいと考えています。ArrayList val; を使用しています。データを取得および設定します。クラスを動的にする方法について誰かがヒントをくれますか。

新規更新 以下のコードは 1 つのマーカーしか表示しないが、すべてのマーカーを表示したい
