event handler not firing

Getting Started Newbie Questions

Hi

I modified the Mapview example to the code shown below, but the program is not getting to the event handler to get the address of my location. Could someone tell me what I am doing wrong please.

Thanks

[code]

–
– Abstract: MapView sample project
– Demonstrates the API for embedded maps and location data (currently iOS-only)

– Version: 1.0

– Sample code is MIT licensed, see http://developer.anscamobile.com/code/license
– Copyright © 2010 ANSCA Inc. All Rights Reserved.

display.setStatusBar( display.HiddenStatusBar )

– Load external Lua libraries (from project directory)
local ui = require( “ui” )

local isAndroid = “Android” == system.getInfo(“platformName”)

if isAndroid then
native.showAlert(“Not supported”, “Maps not yet supported on Android devices.”, {“OK”}, onComplete)
end

local locationNumber = 1 – a counter to display on location labels
local currentLocation, currentLatitude, currentLongitude

local background = display.newImage( “elpasoatnight.png”, true )
background.x = display.contentWidth / 2
background.y = display.contentHeight / 2

–local label = display.newText( “Maps not supported in Corona Simulator.”, 20, 70, native.systemFont, 14 )
–local label2 = display.newText( “(Build for XCode Simulator or iOS device.)”, 20, 95, native.systemFont, 14 )
– Create a native MapView (requires XCode Simulator build or device build)
– You can create multiple maps, if you like…
myMap = native.newMapView( 20, 20, 300, 220 ) – don’t know I need this in order to display buttons
myMap.mapType = “normal” – other mapType options are “satellite” or “hybrid”

– The MapView is just another Corona display object, and can be moved or rotated, etc.
myMap.x = display.contentWidth / 2
myMap.y = 120

– Initialize map to a real location, El Paso, Tx
myMap:setCenter( 31.8470, -106.5892 )

– A function to handle the “mapAddress” event (also known as “reverse geocoding”)
local mapAddressHandler = function( event )
locationText =
"Latitude: " … currentLatitude …
", Longitude: " … currentLongitude …
", Address: " … event.streetDetail … " " … event.street …
", " … event.city …
", " … event.region …
", " … event.country …
", " … event.postalCode

local alert = native.showAlert( “You Are Here”, locationText, { “OK” } )

end

– Create buttons and their functions:

local button2Release = function( event )
– not implemented yet
end

local button1Release = function( event )
– Fetch the user’s current location
currentLocation = myMap:getUserLocation()
currentLatitude = currentLocation.latitude
currentLongitude = currentLocation.longitude
print (“current location”,currentLatitude,currentLongitude) – this prints location fine

– Look up nearest address to this location (this is returned as a “mapAddress” event, handled above)
myMap:nearestAddress( currentLatitude, currentLongitude )

local button2 = ui.newButton{
default = “buttonBlueSmall.png”,
over = “buttonBlueSmallOver.png”,
onRelease = button2Release,
text = “Whos here”,
size = 11,
emboss=true
}
button2.x = display.contentWidth / 8; button2.y = 40

end

local button1 = ui.newButton{
default = “buttonBlueSmall.png”,
over = “buttonBlueSmallOver.png”,
onRelease = button1Release,
text = “U R Here/ck in”,
size = 09,
emboss=true
}

button1.x = display.contentWidth / 8 ; button1.y = 40
– A listener for the address lookup result
Runtime:addEventListener( “mapAddress”, mapAddressHandler ) [import]uid: 95689 topic_id: 17773 reply_id: 317773[/import]

OK, no one seams to be answering any of my posts.

Anyway, I found out it is firing, only I had to build it for the device. Now I have two questions:

  1. I want the address only, no map. Is this possible?

  2. On the “locationText”, I only want the address portion only. I comment out the lat , long and country and zip and it does not run. Can I only get the address from the event handler?

No one seems to be answering any of your posts? That’s not good. Where are your other posts? Links? I’ll try to answer them for you.

Typically if you want someone to provide help with your code you need to provide a plug and play example that people can test.

For the location text, try taking another look at it and see if you get terminal errors - it’s just text so there’s no reason it can’t say anything you like.
