Using a ListModel as a model for map markers

KennSebesta

I might have missed this in the examples, but I cannot find a worked example of how to have points/markers/symbols be linked to a ListModel.

I have an XMLListModel from NOAA which lists all the weather stations across the US and I would like to plot their location with a simple circle. This is pretty simple so I'm sure it's low-hanging fruit for the right approach. It seems that I could create each point through iteratively  calling `ArcGISRuntimeEnvironment.createObject()`, but this doesn't feel "qml-like". I'm hoping to find a view which consumes the model, much like the QML-native MapItemView.

Nothing in the API jumps out at me as appropriate, with the closest being GeoView. However, a GeoView cannot be created directly and is inherited by a MapView and a SceneView, neither of which is appropriate for a model view which consumes a ListModel.

This forum post seems to be asking for the same thing, but it's 6 years old so perhaps the feature has been implemented in the meanwhile.

Questions:

• Is there SDK support for an ArcGIS equivalent of the MapItemView?
• If not, what is the recommended way to create the same behavior?

@KennSebesta , no, it's not possible I'm afraid. You'd need to read the data out and parse it manually.

We do allow nesting of objects (Map nested in a MapView, Graphics nested in a GraphicsOverlay), but they all need to be Runtime objects and declared to utilize that workflow.

On the plus side, it should not be very difficult to parse out the data and create the graphics from any long/lat data in the file. The example I shared is doing exactly that.
