If you are using MapView:

class MapOverlay extends Overlay
{
    @Override
    public boolean draw(Canvas canvas, MapView mapView, 
    boolean shadow, long when) 
    {
       //...
    }

    @Override
    public boolean onTouchEvent(MotionEvent event, MapView mapView) 
    {   

        if (event.getAction() == 1) {                
            GeoPoint p = mapView.getProjection().fromPixels(
                (int) event.getX(),
                (int) event.getY());
                // send the intent from here to your next activity with the GeoPoint coords.
                Toast.makeText(getBaseContext(), 
                    p.getLatitudeE6() / 1E6 + "," + 
                    p.getLongitudeE6() /1E6 , 
                    Toast.LENGTH_SHORT).show();
        }                            
        return false;
    }        
}

u mean i can set this as a background of my activity, and then launch an intent using those co-ordinates? – Pratik Bhat Oct 31 '11 at 06:41
Perhaps you need to [try out this tutorial to really understand this code](http://mobiforge.com/developing/story/using-google-maps-android) – Reno Oct 31 '11 at 06:44
this works, but it wil giv a toast even when u lift a finger after dragging, to solve that, i made an overlay class and override the onTap function in it – Pratik Bhat Nov 01 '11 at 04:51

I am not sure if I got your question right. But if your question is how to get the user's location correctly here is a similar question.
