在Google Map Application上弹出Android菜单

Question

I am doing my graduation thesis and I have to do an Android application which shows my location on Google Maps (something I have done), and when I click some pins in the university will pop up some informations for the buildings and if I could when i click them they will redirect to a url.I have done it with Toast but it doesn't fullfill my needs.I have searched and found NooYawk pop up.Here is my code if anyone can help I will be grateful. Ps I am amateur

public class TGpsActivity extends MapActivity {

 MapView mapView=null;
 MapController mapController=null;
 MyLocationOverlay whereAmI=null;

 @Override
 protected boolean isLocationDisplayed(){
        return whereAmI.isMyLocationEnabled();
 }

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



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

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

    Drawable marker=getResources().getDrawable(R.drawable.pushpin);
    marker.setBounds((int) (-marker.getIntrinsicWidth()/2),-marker.getIntrinsicHeight(),(int) (marker.getIntrinsicWidth()/2),0);        
    mapController=mapView.getController();
    mapController.setZoom(15);

    InterestingLocations funPlaces= new InterestingLocations(marker);
    mapView.getOverlays().add(funPlaces);

    GeoPoint pt=funPlaces.getCenterPt();
    int latSpan=funPlaces.getLatSpanE6();
    int lonSpan=funPlaces.getLonSpanE6();
    Log.v("Overlays", "Lat span is " + latSpan);
    Log.v("Overlays", "Lon span is " + lonSpan);

    MapController mc = mapView.getController();
    mc.setCenter(pt);
    mc.zoomToSpan((int) (latSpan*1.5), (int)(lonSpan*1.5));


    whereAmI= new MyLocationOverlay(this, mapView);
    mapView.getOverlays().add(whereAmI);
    mapView.postInvalidate();

}
public class InterestingLocations extends ItemizedOverlay{
    private ArrayList<OverlayItem> locations = new ArrayList<OverlayItem>();
    private GeoPoint center=null;

    public InterestingLocations(Drawable marker){
        super(marker);

        GeoPoint headOffice = new GeoPoint((int)(37.97897823618044*1000000) ,(int)(23.6723855137825*1000000));

            int westEdge=   180000000;
            Iterator<OverlayItem> iter=locations.iterator();
            while(iter.hasNext()){
                GeoPoint pt=iter.next().getPoint();

            center=new GeoPoint((int)((northEdge+southEdge)/2),(int)((westEdge+eastEdge)/2));

        }
        return center;

}

        mapView.setTraffic(false);
        break;
    }
    }
}

[update]

Something more the code for pop up menu is this but i dont want to show the l

@Override
protected boolean onTap(int i) {
  OverlayItem item=getItem(i);
  GeoPoint geo=item.getPoint();
  Point pt=map.getProjection().toPixels(geo, null);

  View view=panel.getView();

  ((TextView)view.findViewById(R.id.latitude))
    .setText(String.valueOf(geo.getLatitudeE6()/1000000.0));
  ((TextView)view.findViewById(R.id.longitude))
    .setText(String.valueOf(geo.getLongitudeE6()/1000000.0));
  ((TextView)view.findViewById(R.id.x))
                          .setText(String.valueOf(pt.x));
  ((TextView)view.findViewById(R.id.y))
                          .setText(String.valueOf(pt.y));

  panel.show(pt.y*2>map.getHeight());

  return(true);
}

@Override
public int size() {
  return(items.size());}}
class PopupPanel {
View popup;
boolean isVisible=false;

PopupPanel(int layout) {
  ViewGroup parent=(ViewGroup)map.getParent();

  popup=getLayoutInflater().inflate(layout, parent, false);

  popup.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
      hide();
    }
  });
}

View getView() {
  return(popup);
}

void show(boolean alignTop) {
  RelativeLayout.LayoutParams lp=new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT
  );

  if (alignTop) {
    lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    lp.setMargins(0, 20, 0, 0);
  }
  else {
    lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    lp.setMargins(0, 0, 0, 60);
  }

  hide();

  ((ViewGroup)map.getParent()).addView(popup, lp);
  isVisible=true;
}

void hide() {
  if (isVisible) {
    isVisible=false;
    ((ViewGroup)popup.getParent()).removeView(popup);
  }
}

尝试在您的位置上添加OnTouchListener并使用Layout Inflator来显示包含您要显示的信息的自定义布局。
