Handle tap events on overlay icons Override

indicating that we have captured the relevant information about the overlay item. In a more serious
application one could replace the Toast with display of a customized view with the title,
snippet text, and additional features like an embedded image, video, or sound, or links to additional
information. The lat and lon variables return the coordinates of the icon that was clicked, which could
be used for custom positioning of a display view.

Methods to set map overlays. In this case we will place a small overlay image at a specified location. Place the marker image as a png file in res drawable- .
For example, the reference to R.drawable.knifefork_small below is to an image file called knifefork_small.png in the project folder res drawable-hdpi.
Can only use lower case letters a-z, numbers 0-9, ., and _ in these image file names. In this example the single overlay item is specified by drawable and the
location of the overlay item is specified by overlayitem. Display food location overlay. If not already displayed, clicking button displays
all food overlays. If already displayed successive clicks remove items one by one.
This illustrates ability to change individual overlay items dynamically at runtime.

foodIsDisplayed = foodIsDisplayed; Remove each item successively with button clicks
} else { itemizedOverlay1.removeItemitemizedOverlay1.size-1;
ifitemizedOverlay1.size 1 foodIsDisplayed = false; }
Added symbols will be displayed when map is redrawn so force redraw now mapView.postInvalidate;
} Display accessibility overlay. If not already displayed, successive button clicks
display each of the three icons successively, then the next removes them all. This illustrates the
ability to change individual overlay items dynamically at runtime.
public void setOverlay2{ int accessLength = accessItem.length;
Create itemizedOverlay2 if it doesnt exist ifitemizedOverlay2 == null {
mapOverlays = mapView.getOverlays; drawable2 = this.getResources.getDrawableR.drawable.marker;
itemizedOverlay2 = new MyItemizedOverlaydrawable2; }
Add items with each click ifitemizedOverlay2.size accessLength{

Method to read route data from server as XML Overlay a route. This method is only executed after loadRouteData completes
on background thread. Class to implement single task on background thread without having to manage
the threads directly. Launch with new RouteLoader.executenew URLurlString. Must be launched from the UI thread and may only be invoked once. Adapted from
example in Ch. 10 of Android Wireless Application Development. Use this to do data load from network on separate thread from main user interface to prevent locking
main UI if there is network delay. public boolean onCreateOptionsMenuMenu menu {
