How to apply ripple background in .NET MAUI Radio Button?

Overview

In .NET MAUI applications, you can enhance the visual interaction of radio buttons by applying a ripple effect background. This article demonstrates how to apply a RippleBackground to the .NET MAUI Radio Button control using the .NET MAUI EffectsView control.

Custom Control Creation

To implement the ripple effect, create a custom control that inherits from SfRadioButton. Below is the code snippet for creating a custom RadioButton:

// Custom Control
#if ANDROID
public class CustomSfRadioButton : SfRadioButton, ITouchListener
#else
public class CustomSfRadioButton : SfRadioButton
#endif
{
    public CustomSfRadioButton()
    {
        
    }
#if ANDROID
    void ITouchListener.OnTouch(Syncfusion.Maui.Core.Internals.PointerEventArgs e)
    {                    
        var effects = this.Parent as SfEffectsView;
        if(e.Action == PointerActions.Pressed)
        {
            if (this.Parent is SfEffectsView)
            {
                effects?.OnTouch(e);
                this.IsChecked = true;
            }
        }
        else if(e.Action == PointerActions.Released)
        {
            if (this.Parent is SfEffectsView)
            {
                effects?.OnTouch(e);                   
            }
        }                                                                   
    }
#endif
}

XAML Implementation

After creating the custom control, use it within your XAML layout as shown below:

<ContentPage.Resources>
    <buttons:SfRadioGroupKey x:Key="radioButtonGroup"/>
</ContentPage.Resources>

<StackLayout Padding="10,0">
    <Label Text="Pizza Toppings:" FontAttributes="Bold"/>
    <VerticalStackLayout Padding="30,0">
        <core:SfEffectsView RippleBackground="Red">
            <local:CustomSfRadioButton Text="Pepperoni"  
                                       GroupKey="{StaticResource radioButtonGroup}" />
        </core:SfEffectsView>

        <core:SfEffectsView RippleBackground="Red">
            <local:CustomSfRadioButton Text="Chicken" 
                                       GroupKey="{StaticResource radioButtonGroup}"/>
        </core:SfEffectsView>

        <core:SfEffectsView RippleBackground="Red">
            <local:CustomSfRadioButton  Text="Mushrooms"  
                                        GroupKey="{StaticResource radioButtonGroup}"/>
        </core:SfEffectsView>

        <core:SfEffectsView RippleBackground="Red">
            <local:CustomSfRadioButton  Text="BBQ chicken pizza"  
                                        GroupKey="{StaticResource radioButtonGroup}"/>
        </core:SfEffectsView>
    </VerticalStackLayout>
</StackLayout>

By following the steps above, you can successfully apply a ripple effect background to the SfRadioButton in your .NET MAUI application, enhancing the user experience with a modern and interactive design.
