Powerful dialog in Android

Dialog (pop-up box effect) is often used in Android, which is very powerful and can simulate n pop-up box effects. :

The following uses a small instance to demonstrate the powerful dialog in Android. The Code has been commented out in detail. You may try to manually comment on it.

Of course, due to the time relationship, there are still some functions not completed, some of the first display effects may also have bugs, and the Code also has a lot to be optimized. I hope you will be enthusiastic about this.

The following is the code (a little long ):
