• CardsView sample: https://github.com/AndreiMisiukevich/CardView/blob/master/PanCardViewSample/PanCardViewSample/Views/CardsSampleView.cs

Setup

• Available on NuGet: CardsView
• Add nuget package to your Xamarin.Forms .NETSTANDARD/PCL project and to your platform-specific projects
• Add (AFTER Forms.Init(...)):
  • CardsViewRenderer.Preserve() AppDelegate in FinishedLaunching for iOS
  • CardsViewRenderer.Preserve() MainActivity in OnCreate for Android

C#:

-> Create CardsView and setup it

var cardsView = new CardsView
{
    ItemTemplate = new DataTemplate(() => new ContentView()) //your template
};
cardsView.SetBinding(CardsView.ItemsSourceProperty, nameof(PanCardSampleViewModel.Items));
cardsView.SetBinding(CardsView.SelectedIndexProperty, nameof(PanCardSampleViewModel.CurrentIndex));

-> Optionaly you can create ViewModel... or not... as you wish

-> Indicators bar (For CarouselView, perhaps). It's easy to add indicators -> Just add IndicatorsControl into your carouselView as a child view.

carouselView.Children.Add(new IndicatorsControl());

XAML:

<cards:CarouselView 
    ItemsSource="{Binding Items}"
    SelectedIndex="{Binding CurrentIndex}">
    <cards:CarouselView.ItemTemplate>
        <DataTemplate>
            <ContentView>
                <Frame 
                    VerticalOptions="Center"
                    HorizontalOptions="Center"
                    HeightRequest="300"
                    WidthRequest="300"
                    Padding="0" 
                    HasShadow="false"
                    IsClippedToBounds="true"
                    CornerRadius="10"
                    BackgroundColor="{Binding Color}">
                    
                    <Image Source="{Binding Source}"/> 
                    
                </Frame>
            </ContentView>
        </DataTemplate>
    </cards:CarouselView.ItemTemplate>

    <controls:LeftArrowControl/>
    <controls:RightArrowControl/>
    <controls:IndicatorsControl/>
</cards:CarouselView>

Also you are able to manage IndicatorsControl appearing/disappearing. For example if user doesn't select new page during N miliseconds, the indicators will disappear. Just set ToFadeDuration = 2000 (2 seconds delay before disappearing) You manage LeftArrowControl and RightArrowControl as well as IndicatorsControl (ToFadeDuration is presented too).

Indicators styling:

 <ContentPage.Resources>
    <ResourceDictionary>
        <Style x:Key="ActiveIndicator" TargetType="Frame">
            <Setter Property="BackgroundColor" Value="Red" />
        </Style>
        <Style x:Key="InactiveIndicator" TargetType="Frame">
            <Setter Property="BackgroundColor" Value="Transparent" />
            <Setter Property="OutlineColor" Value="Red" />
        </Style>
    </ResourceDictionary>
</ContentPage.Resources>

... 

<controls:IndicatorsControl ToFadeDuration="1500"
          SelectedIndicatorStyle="{StaticResource ActiveIndicator}"
          UnselectedIndicatorStyle="{StaticResource InactiveIndicator}"/>

if you want to add items directly through xaml

...
    <cards:CarouselView.ItemsSource>
            <x:Array Type="{x:Type View}">
                <ContentView>
                    <Image Source="yourImage.png"/>
                </ContentView>
                <RelativeLayout>
                    <Button Text="Click" />
                </RelativeLayout>
                <StackLayout>
                    <Label Text="any text"/>
                </StackLayout>
            </x:Array>
    </cards:CarouselView.ItemsSource>
...

if you want to achieve scale or opacity changing effects for side views (ScaleFactor & OpacityFactor), you should mange corresponding properties in processor and pass them to view constructor via x:Arguments:

<ContentPage 
    ...
    xmlns:cards="clr-namespace:PanCardView;assembly=PanCardView"
    xmlns:proc="clr-namespace:PanCardView.Processors;assembly=PanCardView">

...

<cards:CoverFlowView 
      PositionShiftValue="145"
      ItemsSource="{Binding Items}">

      <x:Arguments>
          <proc:CoverFlowProcessor ScaleFactor="0.75" OpacityFactor="0.25" />
      </x:Arguments>

  <cards:CoverFlowView.ItemTemplate>
      <DataTemplate>
         <Frame
             Margin="80">
               
              ....

          </Frame>
      </DataTemplate>
  </cards:CoverFlowView.ItemTemplate>

</cards:CoverFlowView>

...

-> If you want to customize indicators, you need set SelectedIndicatorStyle and/or UnselectedIndicatorStyle, or you are able to extend this class and override several methods. Also you can customize position of indicators (You need to set Rotation / AbsoluteLayout Flags and Bounds etc.)

This class is describing default indicators styles (each default indicator item is Frame) https://github.com/AndreiMisiukevich/CardView/blob/master/PanCardView/Styles/DefaultIndicatorItemStyles.cs

MORE SAMPLES you can find here https://github.com/AndreiMisiukevich/CardView/tree/master/PanCardViewSample

Custom Animations

You are able to create custom animations, just implement IProcessor or extend existing processors (change animation speed or type etc.) https://github.com/AndreiMisiukevich/CardView/tree/master/PanCardView/Processors

Workarounds

-> If you want to put your cardsView/carouselView INTO a TabbedPage on Android:

1. Add an event handler for the UserInteraction event
2. On UserInteractionStatus.Started: Disable TabbedPage Swipe Scrolling
3. On UserInteractionStatus.Ending/Ended: Enabled TabbedPage Swipe Scrolling

Example:

1. TabbedPage:

public partial class TabbedHomePage : Xamarin.Forms.TabbedPage
{
    public static TabbedHomePage Current { get; private set; }

    public TabbedHomePage()
    {
        Current = this;
    }

    public static void DisableSwipe()
    {
        Current.On<Android>().DisableSwipePaging();
    }
    
    public static void EnableSwipe()
    {
        Current.On<Android>().EnableSwipePaging();
    }
}

2. Page with CardsView/CarouselView:

public PageWithCarouselView()
{
    InitializeComponent();

    carouselView.UserInteracted += CarouselView_UserInteracted;
}

private void CarouselView_UserInteracted(PanCardView.CardsView view, PanCardView.EventArgs.UserInteractedEventArgs args)
{
    if (args.Status == PanCardView.Enums.UserInteractionStatus.Started)
    {
        TabbedHomePage.DisableSwipe();
    }
    if (args.Status == PanCardView.Enums.UserInteractionStatus.Ended)
    {
        TabbedHomePage.EnableSwipe();
    }
}

-> If you don't want to handle vertical swipes or they interrupt your scrolling, you can set IsVerticalSwipeEnabled = "false"

-> If all these tricks didn't help you, you may use IsPanInteractionEnabled = false This trick disables pan interaction, but preserve ability to swipe cards.

-> If you get crashes during ItemsSource update, try to add/set items in Main Thread (Device.BeginInvokeOnMainThread)

-> GTK use click / double click for forward/back navigation.
