Question

I have an android app that takes an array from a website

{“d”:[{“latitude”:-1.0,”longitude”:-1.0,”time”:”07:14 PM 01/18/2038″,”most_recent”:”1″,”user_id”:”4e3f2c6659f25a0f8400000b”},{“latitude”:-1.0,”longitude”:-1.0,”time”:”07:14 PM 01/18/2038″,”most_recent”:”0″,”user_id”:”4e3f2c6659f25a0f8400000b”},{“latitude”:-1.0,”longitude”:-1.0,”time”:”07:14 PM 01/18/2038″,”most_recent”:”0″,”user_id”:”4e3f2c6659f25a0f8400000b”},{“latitude”:34.0608,”longitude”:-118.454,”time”:”07:14 PM 01/18/2038″,”most_recent”:”1″,”user_id”:”4e3da65e59f25a3956000005″},{“latitude”:34.0608,”longitude”:-118.454,”time”:”07:14 PM 01/18/2038″,”most_recent”:”0″,”user_id”:”4e3da65e59f25a3956000005″},{“latitude”:34.0608,”longitude”:-118.454,”time”:”07:14 PM 01/18/2038″,”most_recent”:”0″,”user_id”:”4e3da65e59f25a3956000005″}]}

as you can see each item has a latitude and longitude component as well as an id.

How do I modify this program to show either a green pin R.drawable.greenpin or a blue pin R.drawable.bluepin for “user_id”:”4e3f2c6659f25a0f8400000b” or “user_id”:”4e3da65e59f25a3956000005″ for each of the items in the array ( should be three blue pins and three green pins at these locations)

public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when)
{ 
super.draw(canvas,mapView,shadow);
Point screenPts=new Point();
mapView.getProjection().toPixels(p,screenPts);
Bitmap bmp=BitmapFactory.decodeResource(getResources(),R.drawable.greenpin);
canvas.drawBitmap(bmp,screenPts.x,screenPts.y-50,null);
return true;
}
}

//to add the location marker
MapOverlay mapOverlay=new MapOverlay();
List<Overlay> listOfOVerlays=mapView.getOverlays();
listOfOverlays.clear();
listOfOverlays.add(mapOverlay);

The method that I have confuses me a bit because it draws the point based on the screen point. I would rather add these points by inserting the pins by the longitude and latitude of the arrays.

Answer 1

I don’t understanding what u want but in my case this code work for me, for put marker in appropriate lat,long address.

    myPoint = new GeoPoint(((int) LATITUDE_Add) * 1E6),(int)LONGITUDE_Add) * 1E6));
drawable = getResources().getDrawable(R.drawable.marker_blue);
itemizedoverlay = new MapOverLay(drawable, MapPage.this, mapview);
OverlayItem overlayitem = new OverlayItem(myPoint, address, "");

 itemizedoverlay.addOverlay(overlayitem);
 mapOverlays.add(itemizedoverlay);
 mapview.getController().animateTo(myPoint);

Thnx.
