In my Application, I want to show a 'Map' like below in the picture, so is there any special method to add this Because we can't add one Activity into another Activity so I am searching for a special method or technique, no doubt many application are using this but I am not familiar with that method, I searched but could not find any appropriate answer.
An Activity can never host an Activity. You can only add a MapFragment.

I want to learn how to create custom android views. I don't want to use any library. I have looked searched for it.
You can create your own view using layouts and inject into the view by dialog. On click you can handle the calendar object.

I have a activity, named MainActivity. I want to recall the onCreate activity in this activity(MainActivity).
MainActivity.this.onCreate(....);
How can I do this?
You can but you should not. You should mention your requirement. But if you want to execute the same code that is in onCreate then you can take out that code to separate method and call that in onCreate and from the place where you wanted to call onCreate from.
Find more info on this here.

I inherited some code where there are some Activity classes that are completely commented out. I'm having trouble figuring out where the activity code is actually happening and so I'm just wondering if /* at the beginning of a class might have some special significance to Android that I don't know about
No, it has no special meaning. The code is somewhere and it's not commented out.
