        public void onDestroy()
        Overrides:

      • onLongPress

        public boolean onLongPress​(org.mapsforge.core.model.LatLong tapLatLong,
                           org.mapsforge.core.model.Point layerXY,
                           org.mapsforge.core.model.Point tapXY)
        GroupLayer does not have a position, layerXY is null.
        Overrides:
        onLongPress in class Layer
        Parameters:
        tapLatLong - the geographic position of the long press.

      • setDisplayModel

        public void setDisplayModel​(DisplayModel displayModel)
        Description copied from class: Layer
        The DisplayModel comes from a MapView, so is generally not known when the layer itself is created. Maybe a better way would be to have a MapView as a parameter when creating a layer.

        Parameters:
        displayModel - the displayModel to use.
