MapsGL Android - Map Controller

A map controller provides the interface between your map view, which is created using Mapbox, and the functionality available within the MapsGL SDK. Therefore, you will be working with a map controller instance most of the time when managing data sources and layers.

The following example demonstrates how to set up a map controller using Mapbox:


// Read in the Xweather account and access keys for the SDK that you set in strings.xml
var xweatherAccount = XweatherAccount(
    getString(R.string.xweather_client_id),
    getString(R.string.xweather_client_secret)
)
 
var mapView = binding.mapView
 
// Create the mapcontroller once the all the layout elements are loaded:
binding.mapView.viewTreeObserver.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {
    override fun onGlobalLayout() {
        binding.mapView.viewTreeObserver.removeOnGlobalLayoutListener(this)
 
        // Create a map controller that corresponds to the selected mapping library,
        // passing in your `mapView` and `xweatherAccount` instances.
        mapController = MapboxMapController(mapView, baseContext, xweatherAccount, this@MainActivity)
 
        with(mapController) {
            // Set the map to mercator mode:
            mapboxMap.setProjection(projection(ProjectionName.MERCATOR))
 
            // Listen for the loading of the map to finish:
            mapboxMap.subscribeMapLoaded(mapLoadedCallback)
        }
    }
})

With a map controller created and the map loaded, you can start adding data to your map. To do so, you can quickly add our pre-configured weather layers to your map without needing to create the data sources and layers directly.


// After the map has finished loading, add your weather layers
val mapLoadedCallback = MapLoadedCallback {
    mapController.addWeatherLayer(WeatherService.Temperatures(mapController.service))
}
