    <p>Yes - you can use fluent bindings in Android if you want to.</p> <p>Exactly the same code should work.</p> <p>You'll need to get references to the ui controls using <code>FindViewById&lt;Type&gt;()</code>, then you can bind them.</p> <p>For example, in TipCalc you can add identified controls like:</p> <pre><code> &lt;EditText android:id="@+id/FluentEdit" android:layout_width="fill_parent" android:layout_height="wrap_content" android:inputType="number" android:textSize="24dp" android:gravity="right" /&gt; </code></pre> <p>and then implement binding using:</p> <pre><code> protected override void OnViewModelSet() { SetContentView(Resource.Layout.View_Tip); var edit = this.FindViewById&lt;EditText&gt;(Resource.Id.FluentEdit); var set = this.CreateBindingSet&lt;TipView, TipViewModel&gt;(); set.Bind(edit).To(vm =&gt; vm.SubTotal); set.Apply(); // for non-default properties use 'For': // set.Bind(edit).For(ed =&gt; ed.Text).To(vm =&gt; vm.SubTotal); // you can also use: // .WithConversion("converter", "optional parameter") // .OneTime(), .OneWay() or .TwoWay() } </code></pre> <p>Additionally, you can convert any FooActivity into a data-binding MvxFooActivity by:</p> <ul> <li>inheriting from FooActivity to provide events from lifetime events in an EventSourceFooActivity </li> <li>inheriting from EventSourceFooActivity to provide a datacontext in an MvxFooActivity</li> <li>you can then write your code inside activities inheriting from MvxFooActivity</li> </ul> <p>To see, the code required, see:</p> <ul> <li><a href="https://github.com/slodge/MvvmCross/blob/v3/Cirrious/Cirrious.MvvmCross.Droid.Fragging/MvxEventSourceFragmentActivity.cs" rel="nofollow noreferrer">https://github.com/slodge/MvvmCross/blob/v3/Cirrious/Cirrious.MvvmCross.Droid.Fragging/MvxEventSourceFragmentActivity.cs</a></li> <li><a href="https://github.com/slodge/MvvmCross/blob/v3/Cirrious/Cirrious.MvvmCross.Droid.Fragging/MvxFragmentActivity.cs" rel="nofollow noreferrer">https://github.com/slodge/MvvmCross/blob/v3/Cirrious/Cirrious.MvvmCross.Droid.Fragging/MvxFragmentActivity.cs</a></li> </ul> <p>You'll see the same code in all the mvx adapted Activities - MvxActivity, MvxTabActivity, ... There is a little cut-and-paste here, but as much code as possible is place in shared extension methods.</p> <p>In previous versions, people have used this technique to bind monogame and google ads activities - eg see <a href="https://stackoverflow.com/questions/13201174/insert-a-monogame-view-inside-mvvmcross-monodroid-activity/13201800#13201800">Insert a Monogame view inside MvvmCross monodroid Activity</a></p>

    1. COHi Stuart, I'm trying the 1st method, but it's giving null ref exception on the Bind() call. I inherit my activity from Activity, IMvxBindingContextOwner, IMvxLayoutInflater, IMvxView and create the binding context and viewmodel myself. Note that since I can't inherit from MvxActivity, I can't call this.CreateBindingSet, I also have to create the MvxAndroidBindingContext myself. Any idea what's wrong? My attempt to see what's going on by compiling the MVVMCross source code also failed, VS says it could not load system.windows.dll assembly, although I removed the ref in Cirrious.CrossCore

    2. COWay too many questions/comments in that last comment. I'll change 'alternatively' in my answer to additionally. For everything else in that comment, I'm not getting into a comment conversation - stackoverflow frowns on these.

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.
