您可以添加依赖于平台的资源,并将您的因素绑定到其中:
<RelativeLayout Grid.Row="0" VerticalOptions="StartAndExpand" HeightRequest="112.5">
<RelativeLayout.Resources>
<ResourceDictionary>
<OnPlatform x:TypeArguments="x:Double" iOS="0.30" Android="0.25" x:Key="XFactor" />
</ResourceDictionary>
</RelativeLayout.Resources>
<Image Source="close.png" Scale="0.3" RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor={StaticResource XFactor}}">
<Image.GestureRecognizers>
<TapGestureRecognizer Command="{Binding CancelPopUpCommand}"/>
</Image.GestureRecognizers>

</RelativeLayout>
