Get integer value against Picker.Items in Xaml

Here is my code in xaml

<Picker Title="Privacy" SelectedItem="{Binding PrivacyLevel}">
  <Picker.Items>
      <x:String>Public</x:String>
      <x:String>Private</x:String>
  </Picker.Items>
</Picker>

The property PrivacyLevel is of integer type. I want to store 1 if public and 2 if Private. How?

You can use a class to represent your items, maybe a PrivacyLevel class. Instead of binding your Picker against a string's list you can use a List<PrivacyLevel>. PrivacyLevel class contains both, the text you want to display and the value you want to persist/store/use. 

public class PrivacyLevel
{
    public string Name { get; set; }
    public int Value { get; set; }
}

Then populate your ViewModel with the options.

    public List<PrivacyLevel> Privacies { get; set; } = new List<PrivacyLevel>()
    {
        new PrivacyLevel(){Name = "Public",Value = 1},
        new PrivacyLevel(){Name = "Private",Value = 2}
    };

    private PrivacyLevel _privacy;
    public PrivacyLevel Privacy{
       get{
          return _privacy;
       }
       set{
          _privacy=value;
          OnPropertyChanged();
       }
    }

And finally, 

    <Picker Title="Privacy"
            ItemsSource="{Binding Privacies}"
            SelectedItem="{Binding Privacy}"
            ItemDisplayBinding="{Binding Name}"/>

Remeber that now you have a SelectedItem which is an object and if you want to use the Value, you need access to its property.
