Our Android user interface will start at MainPage, so we need to add a new file called MainPage.xml, and a new MvxActivity called MainPage.cs. Firstly, add in a new folder called Views; this is where we will be storing our MvxActivities. Let's add a new file called MainPage.cs to the Views folder, and create a new file in the Resources | Layout folder called Main.xml. Our Main.xml is going to start with a LinearLayout and contain four elements: ImageView, TextView, and two Buttons:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:local="http://schemas.android.com/apk/res-auto" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:gravity="center"> 
    <ImageView 
        android:id="@+id/AudioImage" 
        android:layout_width="200dp" 
        android:layout_height="200dp" 
        android:src="@drawable/audio" /> 
    <TextView 
        android:id="@+id/DescriptionText" 
        android:textSize="32sp" 
        android:layout_marginBottom="5dp" 
        android:layout_marginTop="5dp" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        local:MvxBind="Text DescriptionMessage" /> 
    <Button 
        android:id="@+id/AudioPlayerButton" 
        android:layout_width="200dp" 
        android:layout_height="wrap_content" 
        local:MvxBind="Text AudioPlayerTitle; Click AudioPlayerCommand" /> 
    <Button 
        android:id="@+id/ExitButton" 
        android:layout_width="200dp" 
        android:layout_height="wrap_content" 
        local:MvxBind="Text ExitTitle; Click ExitCommand" /> 
</LinearLayout> 

Let's look more closely at the local:Mvxbind properties on the Buttons and TextView. This is where we will set up our bindings to the view-model. We must also add this line:

xmlns:local="http://schemas.android.com/apk/res-auto" 

Does this look familiar?

It is the same as our XAML sheets in Xamarin.Forms; we must import this namespace so we can use the binding properties on our UI elements.
