Map widget problem(s)

[russel18]

Hello fellow LiveCoders,

I have a problem implementing a map widget for my Android app.
I want to display markers but I just can't get them to show up on the map.
I use the example code provided in the Dictionary.
See my code here:

Code: Select all

 
 on openCard
  local tMarkers, tMarkerData
   set the region of widget "Map" to "55 .9533,-3 .1883, 10, 10"
   set the centerCoordinates of widget "Map" to "55 .9533,-3 .1883"
   put "55 .9533,-3 .1883" into tMarkerData["coordinates"]
   put "Centre of Edinburgh" into tMarkerData["title"]
   put tMarkerData into tMarkers["Edinburgh"]
   set the markers of widget "Map" to tMarkers
   end openCard

I use the spaces inside the coordinates because otherwise the forums wouldn't let me post it, thinking they're external URLs. In my code, the spaces are not there.
As you can see, I'm doing it exactly like in the Dictionary example but neither the marker is shown nor is the map centered at the coordinates that I'm submitting.
I just don't see my mistake here, hope that anyone can help me.

Since the map widget is not opening on an emulator for me, for whatever reason,
I test my application by saving it as standalone and then moving it to my phone.
The map is shown there, but like I said, with no markers and wrongly centered.

What am I missing here?

Hello Russel,

Welcome to the forum.

The map widget did not like the spaces in your coordinates, it did not accept it as numbers.
More precisely the spaces in the coordinates. The dictionary example is correct.
This works for me in LC 9.6.1

Code: Select all

on mouseUp
   local tMarkers, tMarkerData
   set the region of widget "Map" to "55.9533,-3.1883,10,10"
   set the centerCoordinates of widget "Map" to "55.9533,-3.1883"
   put "55.9533,-3.1883" into tMarkerData["coordinates"]
   put "Centre of Edinburgh" into tMarkerData["title"]
   put tMarkerData into tMarkers["Edinburgh"]
   set the markers of widget "Map" to tMarkers
end MouseUp

Please note that polylines stopped working for the map widget starting version LC 9.0.4

We will update you when the status of this report changes.

A year later and still waiting . . . come on.

@Bernd, he said he added the spaces due to forum restrictions on new users.

Maybe an inclusion is missing?

Oh, I missed that he intentionally added the spaces. I can not think of any inclusion that would be needed since the widget does show on his phone but probably with the default coordinates.
I have no idea why it does not work then.

Kind regards

Did you include internet in the app? There is an internet permission in the Android pane in standalone settings, as well as in the inclusions. If you do see a map at all then I'd assume you already have those but double check.

Otherwise I can't imagine what might be wrong.

Hello all,

thank you for your replies.

I got it working by adding a button setting up the markers.
As you can see in my previous code, it was inside the openCard command because I wanted to markers to be shown on opening the card. I don't know why, but it didn't work for me. After adding the button und putting said script inside the mouseUp command, the markers show up correctly. Not exactly my wanted solution but I'm fine with it.

Thank you all

I tested your code in an openCard handler in the IDE and it worked. Maybe some other things in the openCard handler prevents it from working.

You could also try

Code: Select all

on openCard
   -- other code here
   send "doMap" to me  in 20 milliseconds
end openCard

on doMap
   -- your code to set  the map
end doMap

This will give the system a bit of time to do openCard and when it is finished it will set the map.

Maybe that works.

Kind regards
Bernd
