如何在Xamarin Forms跨平台中绑定图像集合

Question

In WPF , I can easily bind a collection of image sources to a WrapPanel with image template for instance:

<ItemsControl ItemsSource="{Binding YourChildItems}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <WrapPanel/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
</ItemsControl>

I cannot find an alternative Cross-platform Xamarin Forms way of binding my Image collection to any panel based control.

Answer 1

There is an equivalent of ItemsControl in Xamarin.Forms labs called RepeaterView . It has support for item DataTemplate as well as ItemsPanelTemplate. Check the wiki page on GitHub and this forum thread for examples

Answer 2

1. Go to here and download WrapLayout.cs .
2. Add it your project in Visual Studio.

3. Then you should define its namespace in xaml

   xmlns:xf="clr-namespace:Xamarin.Forms"

4. You should use it like this code:

<ScrollView>
     <xf:WrapLayout x:Name="wrp" />   
</ScrollView>

5. Finally you can add items in code behind.
