android - calling the onCreate method from the same class

Question

Can I call the onCreate method of a particular activity from the same activity ? Like upon clicking a button ,I will create a new tab and I want to run the same code as contained by the onCreate method of the current activity again.

Answer 1

Activity#onCreate() is a lifecycle method and should never be called directly by your own code. If you want to reuse a piece of logic, factor it out into its own method and call the same from both the onCreate() and the place where you want to reuse it.

Ideally, the setup code that an Activity requires to build and initialize itself should be run only once in its lifetime. So, placing something that also needs to be called on a button-click there, points at bigger problems with your code.
