How to display label infomation

zijianzhu — Tue, 20 May 2014 07:14:13 GMT

Hello,
I am currently doing an Android project which shows the plan of networks. I have an online mapservice and feature service which contains the label infomation. But neither of them can display the label information in the map. Could someone tell me how to do it?

Hi Zijian,

Generally speaking, there are two methods to this:

If you want the map service to automatically show labels, you need to set up labels in your data in ArcMap before you publish it as a map service. Labels are only supported on map services. For details on making a map with labels in ArcMap, see http://resources.arcgis.com/en/help/main/10.2/index.html#/Essential_labeling_concepts/00s80000000t000000/.

However, if you wish to pull in attribute information from the feature service to setup and draw the label in android, check out this: https://developers.arcgis.com/android/api-reference/reference/com/esri/core/map/LabelingInfo.html

Hope it helps point your project in the right direction.

Cheers,
Raymond

As there is a huge number of geomotrys, I think the second one is not so good. But if I use the first one, I can not edit the attribut of the geometry. So if I can use the featureLayer(featureService) to display the plan and mapsercive to display the label info, the problem will be solved. But how to only display the label info? I have the mapservice, how can I use it, the ArcGISTiledMapServiceLayer doesn't work, neither featureLayer, is there any other way? Thanks for your helping

Hi Zijian,

Yes, you can use Feature Service to support editing functionalities while using the Map Service to display the label as per my previous suggestion from Method 1, that is, author the map with proper labelling. Whenever a geometry's attribute is added/updated through the Feature Service, the Map Server will be able to render new map images with the updated information.

For this to happen, you cannot use a TileMapServiceLayer which lets you to work with a cached map service resource exposed by the ArcGIS Server REST API. A cached service accesses tiles from a cache instead of dynamically rendering images. For dynamic map services, see https://developers.arcgis.com/android/api-reference/reference/com/esri/android/map/DynamicLayer.html.

Let me know if I understood you correctly.

Cheers,
Raymond

Hi Raymond,

Your suggestion is really helpful, now I want to use ArcGISDynamicMapServiceLayer to display the label info, but the problem is how I can only display the label info without the symbols. This is my code.

This is the map service

DynamicLayer li = new ArcGISDynamicMapServiceLayer(this.getResources()
    .getString(R.string.feature_url));
  mMapView.addLayer(li);

I can display neither symbol nor label info. That is really strange. When I use the featureLayer, I can at least display symbols.

Thanks for your help.

Hi Zijian,

Can you share your Map Service and Feature Service URL for us to check the service parameters?

Hello,

Ive only seen labelingInfo being cast on dynamiclayer (by using DrawingInfo) in android apps. Any advices how can I cast it on ArcGISFeatureLayer? Thanks!
