Добавление информацииЗакрыть верхнюю часть маркера Google Map

Question

Я хочу добавить информационное окно поверх каждого маркера, когда пользователь нажимает маркер. Вот мой код. Маркер отлично, мне нужно, чтобы поверх него появилось только инфоуправление. Как я могу добиться этого, вот мой код

public class MainActivity extends MapActivity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     MapView mapView = (MapView) findViewById(R.id.mapview); 
     mapView.setBuiltInZoomControls(true); 
     mapView.setSatellite(true); 

     Drawable makerDefault = this.getResources().getDrawable(R.drawable.marker_default); 
     MyItemizedOverlay itemizedOverlay = new MyItemizedOverlay(makerDefault); 

     Drawable windmill = getResources().getDrawable(R.drawable.windmill); 
     Drawable bigBen = getResources().getDrawable(R.drawable.big_ben); 
     Drawable eiffelTower = getResources().getDrawable(R.drawable.eiffel_tower); 

     itemizedOverlay.addOverlayItem(52372991, 4892655, "Amsterdam", windmill); 
     itemizedOverlay.addOverlayItem(51501851, -140623, "London", bigBen); 
     itemizedOverlay.addOverlayItem(48857522, 2294496, "Paris", eiffelTower); 

     mapView.getOverlays().add(itemizedOverlay); 

     MapController mc = mapView.getController(); 
     mc.setCenter(new GeoPoint(51035349, 2370987)); // Dunkerque, Belgium 
     mc.zoomToSpan(itemizedOverlay.getLatSpanE6(), itemizedOverlay.getLonSpanE6()); 

    } 

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

    private class MyItemizedOverlay extends ItemizedOverlay<OverlayItem> { 

     private List<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); 

     public MyItemizedOverlay(Drawable defaultMarker) { 
      super(boundCenterBottom(defaultMarker)); 
     } 

     public void addOverlayItem(int lat, int lon, String title, Drawable altMarker) { 
      GeoPoint point = new GeoPoint(lat, lon); 
      OverlayItem overlayItem = new OverlayItem(point, title, null); 
      addOverlayItem(overlayItem, altMarker); 
     } 

     public void addOverlayItem(OverlayItem overlayItem) { 
      mOverlays.add(overlayItem); 
      populate(); 
     } 

     public void addOverlayItem(OverlayItem overlayItem, Drawable altMarker) { 
      overlayItem.setMarker(boundCenterBottom(altMarker)); 
      addOverlayItem(overlayItem); 
     } 

     @Override 
     protected OverlayItem createItem(int i) { 
      return mOverlays.get(i); 
     } 

     @Override 
     public int size() { 
      return mOverlays.size(); 
     } 

     @Override 
     protected boolean onTap(int index) { 
      Toast.makeText(MainActivity.this, getItem(index).getTitle(), Toast.LENGTH_LONG).show(); 
      return true; 
     } 

    } 

}

SitesOverlay.class

private class SitesOverlay extends ItemizedOverlay<CustomItem> { 
      private List<CustomItem> items; 
      private View view = null; 

      public SitesOverlay() { 
       super(null); 
       items = new ArrayList<CustomItem>(); 
       items.add(new CustomItem(pt, busName, "Bendigo", marker)); 
       boundCenter(marker); 
       populate(); 
      } 

      @Override 
      protected CustomItem createItem(int i) { 
       return (items.get(i)); 
      } 

      @Override 
      public void draw(Canvas canvas, MapView mapView, boolean shadow) { 
       if (!shadow) { 
        super.draw(canvas, mapView, false); 
       } 

      } 

      @Override 
      public int size() { 
       return (items.size()); 
      } 

      public void refresh() { 
       populate(); 
      } 

      public void clear() { 
       items.clear(); 
       resetLastFocuesIndex(); 
      } 

      public void resetLastFocuesIndex() { 
       setLastFocusedIndex(-1); 
      } 

      @Override 
      protected boolean onTap(final int index) { 
       if (view != null) { 
        view.setVisibility(View.GONE); 
        getMapView().removeView(view); 
        getMapView().invalidate(); 
        view = null; 
       } 
       view = getLayoutInflater().inflate(R.layout.balloon_overlay, null); 
       LinearLayout layout = (LinearLayout) view 
         .findViewById(R.id.balloon_main_layout); 
       layout.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 
         LayoutParams.WRAP_CONTENT)); 
       view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 
         LayoutParams.WRAP_CONTENT)); 
       view.setBackgroundResource(R.drawable.balloon_overlay_bg_selector); 
       ImageView image = (ImageView) view 
         .findViewById(R.id.balloon_disclosure); 
       TextView text = (TextView) view 
         .findViewById(R.id.balloon_item_title); 
       text.setText(items.get(index).getTitle()); 

       Projection projection = getMapView().getProjection(); 
       Point point = new Point(); 
       projection.toPixels(items.get(index).getPoint(), point); 

       int x = (int) (view.getWidth()/2f); 
       int y = -marker.getIntrinsicHeight() - 3; 

       MapView.LayoutParams lp = new MapView.LayoutParams(
         ViewGroup.LayoutParams.WRAP_CONTENT, 
         ViewGroup.LayoutParams.WRAP_CONTENT, items.get(index) 
           .getPoint(), x, y + 50, 
         MapView.LayoutParams.BOTTOM_CENTER); 
       getMapView().removeView(view); 
       getMapView().invalidate(); 
       getMapView().addView(view, lp); 
       getMapView().invalidate(); 

       view.setOnClickListener(new OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         if (!items.isEmpty()) { 
          if (view != null) { 
           view.setVisibility(View.GONE); 
           getMapView().invalidate(); 
    //       Intent intent=new Intent(MapLocationActivity.this,); 

          } 
         } 
         getMapView().invalidate(); 
        } 
       }); 
       return true; 
      } 
     } 

     class CustomItem extends OverlayItem { 
      Drawable marker = null; 

      CustomItem(GeoPoint pt, String name, String snippet, Drawable marker) { 
       super(pt, name, snippet); 
       this.marker = marker; 
      } 

      @Override 
      public Drawable getMarker(int stateBitset) { 
       Drawable result = marker; 
       setState(result, stateBitset); 
       return (result); 
      } 

     } 

установить Overlay mapview.getOverlays() добавить (новый SitesOverlay()).

если есть множественный маркер, то

for (int i = 0; i < arrayList.size(); i++) { 
        slat = Double.parseDouble(arrayList.get(i).getLat()); 
        vlong = Double.parseDouble(arrayList.get(i).getvLong()); 
        pt = new GeoPoint((int) (slat * 1E6), (int) (vlong * 1E6)); 
        Log.e("lat long", "--- "+slat); 
        MapviewActivity.this.mc.animateTo(pt); 
        items.add(new CustomItem(pt, arrayList.get(i).getBuissnessName(), "Bendigo", marker)); 
        boundCenter(marker); 
       }
