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. ...
