I need to get some default theme color values programmatically (e.g. windowBackground, colorPrimary). I'm executing the code from an Activity. My target android API is 21. I'm using a Theme.Material theme. I've tried:

var attributeValue = new Android.Util.TypedValue(); this.Theme.ResolveAttribute(Resource.Attribute.colorPrimary, attributeValue, true)

with different resource identifier, but i always get a Android.Util.DataType.Null value.

Use this code I have tested

For WindowBackground :

Code :

Android.Util.TypedValue a = new Android.Util.TypedValue(); Theme.ResolveAttribute(Android.Resource.Attribute.WindowBackground, a , true); var windowBackgroundDrawable = Application.Context.GetDrawable(a.ResourceId); var windowBackgroundColor = ((Android.Graphics.Drawables.ColorDrawable)windowBackgroundD‌​rawable).Color;

Output My Case is : FAFAFA

For ColorPrimary use this :

Code :

Android.Util.TypedValue a = new Android.Util.TypedValue(); Theme.ResolveAttribute(Android.Resource.Attribute.ColorPrimary, a , true); var colorPrimarya = Application.Context.GetDrawable(a.ResourceId); var colorPrimary = ((Android.Graphics.Drawables.ColorDrawable) colorPrimarya).Color;

Output My Case is : 0072BA

Thanks. I saw what i was missing. Your code needed some improvements to get the actual color: var windowBackgroundDrawable = Application.Context.GetDrawable(a.ResourceId); var windowBackgroundColor = ((Android.Graphics.Drawables.ColorDrawable)windowBackgroundDrawable).Color; Could you add it to your solution?
Yes, of cause. Please, update the second snippet as well. So it can be consistent.
And even if it looks pedantic, please fix the prefixes with colorPrimary
