How do I get the extents for all sublayer?

jackcrawford — Sat, 11 Dec 2021 20:05:18 GMT

I'm new to the Java runtime. I'm trying to get the extent for each sublayer which I assumed would be available by calling

getMapServiceSublayerInfo().getExtent() 

butgetMapServiceSublayerInfo()

always returns null.

I've tried with our map service and the ESRI sample service

http://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer

Guidance would be much appreciated.

Hi Jack: You are explicitly loading the `ArcGISMapImageLayer` but not the sublayer.

ArcGISMapImageLayer mapImageLayer = new ArcGISMapImageLayer("http://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer");
        
mapImageLayer.loadAsync();
mapImageLayer.addDoneLoadingListener(() -> {

    final ArcGISMapImageSublayer testSublayer = (ArcGISMapImageSublayer) mMapImageLayer.getSublayers().get(0);
    testSublayer.loadAsync();

    testSublayer.addDoneLoadingListener(() -> {

        ArcGISMapServiceSublayerInfo testInfo = testSublayer.getMapServiceSublayerInfo();

    });

});‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
