ArcGISMapImageLayer子图层ArcGISMapImageSublayer设置透明度不起作用
ArcGISMapImageSublayer设置透明度不起作用，请问各位大神有知道咋回事的不？
SublayerList sublayers = arcGISMapImageLayer.getSublayers();
ArcGISMapImageSublayer mainMapImageSublayer = (ArcGISMapImageSublayer)sublayers.get(0);
mainMapImageSublayer.setOpacity(0.1f);
mainMapImageSublayer.setVisible(true);
SublayerList sublayers = arcGISMapImageLayer.getSublayers();
ArcGISMapImageSublayer mainMapImageSublayer = (ArcGISMapImageSublayer)sublayers.get(0);
mainMapImageSublayer.setOpacity(0.1f);
mainMapImageSublayer.setVisible(true);
