You can create a bitmap of the GradientDrawable and then look for the colour of a specific pixel.

From this answer:

// create bitmap based on width and height of the gradient drawable
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas =  new Canvas(bitmap);
gd.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
gd.draw(canvas);
// bitmap now contains a bitmap of the gradient drawable
