How can I change default toast message color and background color in android?

I want to create a toast message with background color is white and message color is black. My toast message is:

Toast.makeText(Logpage.this, \"Please Give          


        

Answer 1

I was able to do it by setting the background color filter color and finding the toast resource ID and setting the text color.

Android.Graphics.Color

    /// 
 Creates and displays a toast with the given text. 
    public void Show(string message)
    {
        // Create the toast.
        Toast toast = Toast.MakeText(Android.App.Application.Context, message, ToastLength.Long);

        // Set the background color.
        Android.Graphics.Color c = new Android.Graphics.Color(122, 193, 66, 255);
        Android.Graphics.ColorMatrixColorFilter CMF = new Android.Graphics.ColorMatrixColorFilter(new float[]
            {
                0,0,0,0,(float)c.R,
                0,0,0,0,(float)c.G,
                0,0,0,0,(float)c.B,
                0,0,0,1,0
            });
        toast.View.Background.SetColorFilter(CMF);

        // Set the text color.
        toast.View.FindViewById(Android.Resource.Id.Message).SetTextColor(new Android.Graphics.Color(0, 55, 103, 255));

        // Display the toast.
        toast.Show();
    }
