Answer 1

Yes it is possible you should design our self info window for display information over tap in map i am supply code to you if you are understand that please replay me.

public class MapLocationOverlay  extends Overlay  {

    private boolean isNameAddHold=true;

     private Bitmap bitmap,bitCross,bitMoreInformation;
    int testX,testY,count=0;
    int infoWindowOffsetX,infoWindowOffsetY;
    public String name,address,argName,argAddress,argid;
    //  Store these as global instances so we don't keep reloading every time
    private Bitmap bubbleIcon, shadowIcon;

    private MapLocationViewer mapLocationViewer;
    double toLat, toLng;

    private Paint   innerPaint, borderPaint, textPaint;
    private boolean isRemovePriorPopup=false;
    private boolean temp=true,first=true, firstDraw = true;
    public boolean tempDefaule=true;
    public MoreInformation myMoreInformation;
    public PantryLocation location;

    //  The currently selected Map Location...if any is selected.  This tracks whether an information  
    //  window should be displayed & where...i.e. whether a user 'clicked' on a known map location
    private PantryLocation selectedMapLocation;  

    public MapLocationOverlay(MapLocationViewer mapLocationViewer,PantryLocation arglocation) {

        this.mapLocationViewer = mapLocationViewer;
        location=arglocation;
        bubbleIcon = BitmapFactory.decodeResource(mapLocationViewer.getResources(),R.drawable.bubble);
        shadowIcon = BitmapFactory.decodeResource(mapLocationViewer.getResources(),R.drawable.shadow);
        bitmap = BitmapFactory.decodeResource(mapLocationViewer.getResources(),R.drawable.infowindow);
        bitCross = BitmapFactory.decodeResource(mapLocationViewer.getResources(),R.drawable.crass);
        bitMoreInformation = BitmapFactory.decodeResource(mapLocationViewer.getResources(),R.drawable.more_informations_new);
    }

    @Override
    public boolean onTouchEvent(MotionEvent e, MapView mapView) {
        // TODO Auto-generated method stub
         if (e.getAction() == 0)
         {
             this.tempDefaule=false;
         }
         if (e.getAction() == 1)
         {
             this.tempDefaule=false;
         }
         if (e.getAction() == 2)
         {
             this.tempDefaule=false;
         }
        return super.onTouchEvent(e, mapView);
    }       

    @Override
    public boolean onTap(GeoPoint p, MapView    mapView)  {
        //this.tempDefaule=false;
        //  Store whether prior popup was displayed so we can call invalidate() & remove it if necessary.

        //  Next test whether a new popup should be displayed

            selectedMapLocation = getHitMapLocation(mapView,p);

            mapView.invalidate();       

        //  Lastly return true if we handled this onTap()
        return selectedMapLocation != null;
    }

    @Override
    public void draw(Canvas canvas, MapView mapView, boolean shadow) {

        drawMapLocations(canvas, mapView, shadow);

        }

}

In this code i have design a function draw infowindow
