This is a breadcrumb navigation control that is completely automatic and uses the Navigation stack to get the page titles to generate the breadcrumbs.
The animation for the control is based on this article - A Cool Breadcrumbs Bar with Xamarin Forms Animations…
Also incorporated Xamarin.Forms.Pancake for more customisation options.
Basic example | Production Example |
---|---|
Install the NuGet package into your shared project project
Install-Package Xamarin.Forms.Breadcrumb -Version 2.0.0
To add to a page the first thing we need to do is tell our XAML page where it can find the Breadcrumb control, which is done by adding the following attribute to our ContentPage:
<ContentPage x:Class="DemoApp.Pages.BasePage"
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:breadcrumb="clr-namespace:Breadcrumb;assembly=Xamarin.Forms.Breadcrumb"
xmlns:d="http://xamarin.com/schemas/2014/forms/design"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<ContentPage.Content>
...
</ContentPage.Content>
</ContentPage>
Next up, just add the breadcrumb control onto that page and you're all set.
