P.S. I'm sorry for my style, but it's my first tutorial. I will modify it latter.

I mised one string @string/activity_custom_dialog, you can enter there you title, or add string to the values.
I find tutorial where use this customdialog here

P.P.S. May by I'm not lucky but this code from my tutorial doesn't work in my emulator

I have black background.

To get rid of the black background use "Theme.Dialog". However the alertbox will have a small title-box in the background that you can not hide with "requestWindowFeature(Window.FEATURE_NO_TITLE);".
