Class GeoJsonLayer

  • 
public class GeoJsonLayer
extends Layer

    A class that allows the developer to import GeoJSON data, style it and interact with the imported data.

    To create a new GeoJsonLayer from a resource stored locally {@code GeoJsonLayer layer = new GeoJsonLayer(getMap(), R.raw.resource, * getApplicationContext());}

    To render the imported GeoJSON data onto the layer {@code layer.addLayerToMap();}

    To remove the rendered data from the layer {@code layer.removeLayerFromMap();}

    • Method Detail

      • addLayerToMap

         void addLayerToMap()

        Adds all the GeoJsonFeature objects parsed from the given GeoJSON data onto the map

      • addFeature

         void addFeature(GeoJsonFeature feature)

        Adds a GeoJsonFeature to the layer. If the point, linestring or polygon style is set tonull, the relevant default styles are applied.

        Parameters:
        feature - GeoJsonFeature to add to the layer

      • removeFeature

         void removeFeature(GeoJsonFeature feature)

        Removes the given GeoJsonFeature from the layer

        Parameters:
        feature - feature to remove

      • getBoundingBox

         LatLngBounds getBoundingBox()

        Gets the LatLngBounds containing the coordinates of the bounding box for theFeatureCollection. If the FeatureCollection did not have a bounding box or if the GeoJSONfile did not contain a FeatureCollection then null will be returned.
