Android touch

try to use itemized overlay to draw image and to draw at certain point override the OntouchEvent Method and pass it the lat and long and you will get Image on the touched location if you need some example u can see here

The Android standard View class support touch events. You can react touch events in your custom views and your activities. Android supports multiple pointers, e.g. fingers which are interacting with the screen.

Android touch

The base class for touch support is the MotionEvent class which is passed to Views via the onTouchEvent() method. To react to touch events you override the onTouchEvent() method. The MotionEvent class contains the touch related information.e.g. the number of pointers, the X/Y coordinates and size and pressure of each pointer.

This method returns true if the touch event has been handled by the view. Android tries to find the deepest view which returns true to handles the touch event. If the view is part of another view (parent view), the parent can claim the event by returning true from the onInterceptTouchEvent() method. This would send an MotionEvent.ACTION_CANCEL event to the view which received previously the touch events.

To react to touch events in an activity, register an OnTouchListener for the relevant Views.
