I've been using an AlertDialog object filled with a custom View but now it was required of me to "surround" the window with a semi-transparent white glow as opposed to the default grayish one. I did a similar with the fade-in color of some navigation drawers I have on my app but in that case I had a specific method to quickly help me solve that problem. So far I
