This sample demonstrates how to identify features on a map across different layers present in the map.
Tap on map to get features at that location. The features are returned from different layers in the map.
- MapView
- ArcGISMapImageLayer
- FeatureLayer
- FeatureTable
MapView has a identifyLayersAsync(screenLocation, tolerance, returnPopupsOnly, maximumResults) method that is used in the sample. The method takes a screen location, tolerance, boolean for returning (a pop-up/pop-up and geo-element), and maximum results per layer, which results in a ListenableFuture<List<IdentifyLayerResult>>.
Layer name and a count of identified features held by each IdentifyLayerResult in the ListenableFuture<List<...>> is then taken and written out to a String. Finally, the resulting String is displayed in an Android AlertDialog.
