Does anyone have a working example of a [react-native-maps] working with JSON feed of the marker locations?
I have the map working with hard coded lat/long markers, but would like to get it populated using JSON.
Many thanks for any assistance!
Here you have an example with markers array:

Tell me if you need more help with this code.

I want to display a list of contacts inside a StandardListItem. The data is retrieved from sql with QArrayBytes representing the Image.
The StandardListItem accepts a title, status, description and an image. But setting the image is not working.
How to set the image bytes in QML inside the StandardListItem.
PS: I don't want to make a custom list item component
Thanks you,
You actually need to use "imageSource" not "image". You can see a working example here: https://developer.blackberry.com/cascades/documentation/device_platform/data_access/using_data_source.html
Been fighting that myself, take a look at this sample it uses the QlistDataModel I've been trying to modify it without much success... The documentation is pretty sucky they don't tell you much in there
I'm trying to get a graph of the elevation of a KML file, that KML file being the only input. Ideally the end result would be pretty much exactly like http://gmaps-samples-v3.googlecode.com/svn/trunk/elevation/elevation-profile.html, where you can move your mouse along the graph and it would travel along the KML path. This also is achievable by uploading your own file on http://www.geocontext.org/publ/2010/04/profiler/en/?import=kml however I need it on my site!
I'm just learning JS and seeing as the majority of the code is there, can anyone give me any clues on how to modify it to
1) Accept a KML file as the source data
2) remove the "driving", "walking", etc directions for only the path data
I'm going to start messing around with the code but any clues would be greatly appreciated! Thanks
My suggestion would be to use a third party KML parser like geoxml3 or geoxml-v3 to render your KML as a native Google Maps API v3 polyline, then use the elevation service on that polyline like the example in the documentation
Working example (using geoxml3)
i am using Google Fusion Tables and Google Maps to display geographical data (e.g. markers). My map needs to have a legend, for example by inserting a div on top of the map and the layer. As i am not used to work with API of any kind, i got stuck with this legend problem.
I tried several example codes (most of them provided by google), but none worked for me. I guess that the problem of displaying divs on a map has got something to do with either the styling of the map canvas, the div implementation within the body of the html document or with the framework used (google appengine). But this is just guessing. As i am not a professional with coding, i maybe missed a important point. Maybe the folks here can help me out?
Every hint is appreciated. Thanks.
You can have a look at the code and my example [here (deleted)]. There example includes a code which should display a div, but it doesn't. I've taken it from here (Stackoverflow).
The code you're using is v2 of the Maps API. You'll want to use code that works with v3 of the Maps API, since that is the version you're using on your site.
Have you tried the sample code here?
https://developers.google.com/fusiontables/docs/samples/legend
Copy and paste the legend code from this example into your initialize method, remove the old legend code. If this doesn't work, let me know.
i want to get the latitude and langitude in order to make annotation in mapkit.
i want to run kml file in objective c but nothing happen all are in javascript.
any suggesion
I did a bit of Googling for you.
Grab the Simple-KML parsing library from GitHub and look at the sample project that comes with it and see how it parses out latitude and longitude (which I believe are SimpleKMLPoints?) and then you will be able to make your annotations into MapKit.
Hopefully I set you in the right direction!
I have used Googlemap using titanium framework for iphone,I am able to dispaly 1 pinpoint/marker for given location using latitude and longitude,but when i am going to display multiple markers/pinpoints , not able to show it on Map.
I have tried to create ARRAY of points to display on the google maps, but it is just showing single pinpoint to display it on Map.
Can anybody help me out for how to display multiple pinpoints to google map using tianium.
Any useful link or code will be appreciated!!
