=== 10. Add Mapping Option ===
10.1. Add the Map Option to the manu:<br/>
<source lang="java">
//Show the address on the map
ImageMenuItem mapItem = new ImageMenuItem("Address on Map", 500, 5, MENU_MAP);
_mainScreen.addMenuItem(mapItem);
</source>
10.2. Implement address locator:
<source lang="java">
mapItem.setCommand(new Command(new CommandHandler(){
public void execute(ReadOnlyCommandMetadata metadata, Object context)
{
Student student = (Student) _keywordFilterField.getSelectedElement();
if(student != null)
{
try
{
String address = student.getAddress();
Coordinates co = new Coordinates(45.423488, -75.697929, 0);
Landmark[] landm = Locator.geocode(address, co);
double lon = landm[0].getQualifiedCoordinates().getLongitude()*100000.0 ;
double lat = landm[0].getQualifiedCoordinates().getLatitude()*100000.0;
StringBuffer document = new StringBuffer("<location-document><location lon='");
document.append(lon).append("' lat='").append(lat).append("' label='").append(address);
document.append("' description='Student Address' zoom='10'/></location-document>");
// Invoke maps application for current Contact
Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments(MapsArguments.ARG_LOCATION_DOCUMENT, document.toString()));
} catch(LocatorException ex){
Dialog.alert("cannot get location: " + ex.getMessage());
} catch(Exception ex){
Dialog.alert("map application is not available: "+ ex.getMessage());
}
}
}
}));
