I have a Xamarin.Android project with several single color (black & transparent) png's in my Drawable folder. I want to be able to dynamically make these images different colors by specifying a System.Drawing.Color or Android.Graphics.Color. To put is simply, I need to fill the black area of the png with a dynamically specified color. Is there a way to do this? Thanks.

    Xamarin support ended on May 1, 2024 for all Xamarin SDKs including Xamarin.Forms. For more information, please check: Xamarin official support policy | .NET (microsoft.com). We will recommend you upgrade Xamarin projects to . NET MAUI, please see the Upgrade from Xamarin to .NET & .NET MAUI documentation.

    You can use imageView.SetBackgroundColor(Android.Graphics.Color.Green);,

    I test with transparent png file in the ImageView and set it with above code, it is working.
