With RefreshView

With commented RefreshView

Perhaps related, I'm finding on RC2 that the RefreshView as root of the ContentPage or within a root Grid will not take up the full width of the page. iOS is fine.

I have a similiar scenario where I want the RefreshView to occupy the entire screen. But as of v7.0 it only occupies the size of it's children. Luckily one can play about with the arrangement code.

    /// <summary>
    /// [Android] RefreshView doesn't size itself correctly
    /// https://github.com/dotnet/maui/issues/9008
    /// </summary>
    public sealed class RefreshViewFix : RefreshView
    {
        protected override SizeRequest OnMeasure(double widthConstraint, double heightConstraint)
        {
#if ANDROID
            return new SizeRequest(new Size(widthConstraint, heightConstraint));
#else
            return base.OnMeasure(widthConstraint, heightConstraint);
#endif
        }
    }

Hi @roubachof,

Can you try to repro this again with .NET 7?

Thank you, James
