Android Mapbox Marker Labels
I'm trying to figure out how to make a dynamically generated list of markers display a dynamic text label on the map (not in the infoWindow). I know it's possible because I've used this feature in Mapbox Studio - I just can't figure out how to do it on Android! I considered creating a static Bitmap icon with the text incorporated, but that doesn't seem very flexible compared to the Mapbox Studio version, so I'd like to avoid it if I can! Any suggestions?

You're trying to do what's called data-driven styling
You should use a SymbolLayer
to show text on a map. If the text you want to show is based on GeoJSON Features in your data set, then use the get
expression in the textField
property of a SymbolLayer
.
FeatureCollection featureCollection = FeatureCollection.fromFeatures();
GeoJsonSource geoJsonSource = new GeoJsonSource("source-id", featureCollection);
mapboxMap.addSource(geoJsonSource);
SymbolLayer symbolLayer = new SymbolLayer("layer-id", "source-id")
.withProperties(PropertyFactory.textField(Expression.get("FEATURE-PROPERTY-KEY")));
mapboxMap.addLayer(symbolLayer);
The Annotation Plugin simplifies some of this. Also for reference to see how SymbolLayer
s are used, there is the Mapbox Android demo app.
You can also create a separateSymbolLayer
for the markers. Reference the same GeoJson source as for your text. But for the marker layer, use theiconImage
PropertyFactory method. Bitmap icon = BitmapFactory.decodeResource( Actvity.this.getResources(), R.drawable.marker_image); mapboxMap.addImage("marker-image", icon); then later: SymbolLayer markerLayer = new SymbolLayer("marker-layer-id", "source-id") .withProperties(PropertyFactory.iconImage("marker-image")); mapboxMap.addLayer(markerLayer);

Thanks, this is just what I'm after I think! Do I have an alternative if my source is a dynamically compiled list of marker points in Java? I have a database of locations, and want to add them to a list of markers based on a set of information (so static source files aren't an option, unless I can dynamically draw a few points from such a source?). Thanks for the help! I'm curious about your second suggestion - what's the benefit of doing it this way? Seems a bit more complicated?

Ahh, nevermind my question! That annotation symbolManager is exactly what I needed. I'll just use SymbolOptions for each marker. :) Thanks so much! I'm curious about the negative to my question - am I asking something stupid?

@JakeMadden, not sure what you mean by "I'm curious about the negative to my question" Anyways, sounds like you're figuring things out. Once a GeoJsonSource is added to the map, any number of layers can reference the unique source id in the layer constructor.

@JakeMadden , hard to help 'cause idk what your data looks like. If you can get the lat/long from each location in your database, do List<Feature> featureList = new ArrayList<>(); for (int x = 0; x < listOfLocationsFromDatabase.size; x++) { Point singlePoint = Point.fromLngLat(listOfLocationsFromDatabase.get(x).getLongitude(), listOfLocationsFromDatabase.get(x).getLongitude()); featureList.add(Feature.fromGeometry(singlePoint)); } FeatureCollection featureCollection = FeatureCollection.fromFeatures(featureList);
