Transparent Page In Xamarin.forms

I need to be able to create a transparent Xamarin.Forms page for Android. How can I do this true a page renderer? Now it has a default background color. [assembly: ExportRenderer(t

Solution 1:

If you just want to make your page's background transparent, you don't need to create a custom renderer for this. You can set the background color in PCL.

For example, xaml:

<ContentPagexmlns="http://xamarin.com/schemas/2014/forms"xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"xmlns:local="clr-namespace:NameSpace"x:Class="NameSpace.MainPage"BackgroundColor="Transparent"></ContentPage>

Or in code behind:

publicpartialclassMainPage : ContentPage
{
    publicMainPage()
    {
        InitializeComponent();
        this.BackgroundColor = Color.Transparent;
    }
}

To prove it's transparent, we can use a NavigationPage with colored background for testing in App.xaml.cs:

publicApp()
{
    InitializeComponent();

    MainPage = new NavigationPage(new MainPage())
    {
        BackgroundColor = Color.Red
    };
}
