    <p>I have an MvxFragmentActivity which loads a google map and places markers on the map. The code to create the map and markers is very Droid specific so it is in the Activity. The markers are created based on objects in the ViewModel which each contain lat/long coordinates. This worked fine as long as I loaded the objects in my Init method. I have since moved the load objects method to a service and call it on a different thread. This way the UI is responsive. However, how do I call the method in the Activity when the load is completed?</p> <p>Here is my current code in the Activity (this code shouldn't change, just how it is called):</p> <pre><code> private void InitMapFragment() { foreach (var item in viewModel.Items) { var icon = BitmapDescriptorFactory.FromResource(Resource.Drawable.place_img); var markerOptions = new MarkerOptions() .SetPosition(new LatLng(item.Latitude, item.Longitude)) .InvokeIcon(icon) .SetSnippet(item.DistanceText) .SetTitle(item.Name); var marker = _map.AddMarker(markerOptions); _markerIds.Add(marker.Id, item.Id); } } </code></pre> <p>Code in my viewModel:</p> <pre><code> private void BeginLoadItems() { _loadItemsService.Load(); } // This is triggered by a message private void OnLoadItemsComplete(LoadCompleteMessage message) { Items = message.Items; } </code></pre> <p>Code in my Service:</p> <pre><code> public void Load() { ThreadPool.QueueUserWorkItem(state =&gt; { var results = _repository.Retrieve(); _messenger.Publish(new LoadCompleteMessage(this, results)); }); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
