Cannot turn on individual layer in group layer in DynamicMapServiceLayer

ClementLau — Thu, 22 Dec 2011 23:30:58 GMT

I have a DynamicMapServiceLayer as follow
Group Layer Name (0)
   Individual Layer Name1 (1)
   Individual Layer Name2 (2)
   Individual Layer Name3 (3)

When I turn Group Layer Name (0) on, all Individual Layers are on (shown in MapView). When I turn Group Layer Name (0) off, all Individual Layers are off. How can I only display an Individual layer?

Use ArcGISDynamicMapServiceLayers' getAllLayers() method or getLayers() method to get ArcGISLayerInfo instance, and use ArcGISLayerInfo to control sub_layers individually.

Thank you fengyunshen,

I had done this.

I had try:
ArcGISDynamicMapServiceLayer.getAllLayers()[0].setVisible(true);
ArcGISDynamicMapServiceLayer.getAllLayers()[1].setVisible(false);
ArcGISDynamicMapServiceLayer.getAllLayers()[2].setVisible(true);
ArcGISDynamicMapServiceLayer.getAllLayers()[3].setVisible(false);
-> three sub-layers are shown in MapView.

ArcGISDynamicMapServiceLayer.getAllLayers()[0].setVisible(false);
ArcGISDynamicMapServiceLayer.getAllLayers()[1].setVisible(false);
ArcGISDynamicMapServiceLayer.getAllLayers()[2].setVisible(true);
ArcGISDynamicMapServiceLayer.getAllLayers()[3].setVisible(false);
-> three sub-layers are not shown in MapView.

You can try the following code.

ESRI_DEV2011,

The sample can help you to spot out the problem?

I think that is sth set by design. If you turn the group layer on, all the layers in the group will be turned on. If you turn the group layer off, all the layers in the group will be off. So how to turn on/off certain layers? I think that you don't need to worry about the group layer, just turn on/off the certain layers should work. At least this is my experience with ArcGIS Desktop. I think this should hold true for java script api too. Please try my idea and see if it works.

For what it's worth I'm having the same problem. If the GROUP is set to visible then all layers in the group are displaying, regardless of what I set the individual layers as. If the GROUP is set to invisible then no layers in the group display.

I'm using ARCGIS for android API version 1.01.

There is some useful information regarding the handling of layers visibility (GroupLayers) through the REST API, that may shed some light on this question. Please look at the following documentation link for more information.
