B4A Library GoogleMapsExtras

warwound · Feb 11, 2013

GoogleMapsExtras is an ongoing project to implement more of the Google Maps Android v2 classes in Basic4Android.

Currently the library allows you to create these objects:

Tutorials for each object will be uploaded to the Google Maps Android v2 tutorial thread.

Hi,

I have tested that getting the icons as a resource seems to fix the problem.

Yes it work BUT the icon is crop to 75% :-(
That not look good, how to find a previous version of the google play services jar?

You've put your icon in the res/drawable folder have you?
Have you tried putting it in the res/drawable-nodpi folder instead?

Have a read about the nodpi folder:

No my PNG are in the files folder and when use this code to load then icon on the map that crop

BitmapDescriptor1 = BitmapDescriptorFactory1.FromAsset("current_" & NumberFormat(PointerCenter,1,0) & ".png")

This working very well with the version 21 of google play services jar but got error with version 22
BitmapDescriptor1=BitmapDescriptorFactory1.FromBitmap(LoadBitmap(File.DirAssets, "current_" & NumberFormat(PointerCenter,1,0) & ".png"))

I don't know yet how to load from res folder but i will try to find and try it

Add a callback sub for the Marker Click event and return True from that sub.

HI , i tried to use a panel as view in the InfoWindowsAdapter but it generates an error:

java.lang.IllegalArgumentException: bitmap size exceeds 32bits

any idea ?

how can I hide a value in each marker ? something like a tag property

warwound · Mar 12, 2015

The recommended way is to make use of the Marker id.
Look here: https://developer.android.com/reference/com/google/android/gms/maps/model/Marker.html
See the getId() method?
Each Marker has a unique id - it's of type String.

So create a Map where the Map key is the Marker id and the Map value is this 'tag' object or value that you want to associate with the Marker.

You can now get your 'tag' using the Marker id as a key.

Hi, I would like to realize a info windows like the one I attached. Is it possible?

could you please post an example to get that id?, I can't find that method

warwound · Mar 13, 2015

Look in GoogleMapsExtras - I'm sure there's a method in there somewhere (can't check right now).

Interactive infowindows are not possible.
Have a read of this post: https://www.b4x.com/android/forum/threads/googlemapextra-custom-annotation.30695/#post-230875

An infowindow cannot contain views that individually respond to touch events
You can detect a click on the entire infowindow but not individual views in the infowindow.

OK, but, how the developer of this app did?

https://play.google.com/store/apps/details?id=org.vernazza.androidfuel

Maybe I can put a view upon the map panel, but how can I know the x,y of the pressed marker?

The third screenshot on the Play Store looks like a Panel that drops down from the top of the screen.
It doesn't look like an infowindow to me.
The screenshots that show infowindows all show infowindows with a basic design - no clickable views in them.

GoogleMapsExtras does support the Projection object and you can use it to convert between LatLngs and screen coordinates.

coslad · Mar 14, 2015

You wrong warwound , as you can see in the attached image, clicking on the marker comes up a panel with 3 button.

warwound · Mar 14, 2015

Hmm not sure how that's been achieved...

Maybe he used this workaround:

coslad · Mar 15, 2015

it is just what i search , but , it is too hard to me to implement it , maybe can you insert that capacity into the next update of mapsextra !
