Question

In my application, there are two activity classes. Suppose A and B. Activity B has a member function name myfun(), Is it possible to call myfun of activity B from activity A with starting activity B. If yes, please provide solution

thanks

Answer 1

You can initiate a object of your ActivityB, and than run the member function. (Use it like an normal object)

E.g

 ActivityB act = new ActivityB();
 act.yourMethod();

(the onCreate will not run when using the “new” keyword, only the constructor of ActivityB.)

Btw. If the method is not depending on any special state or member variables of the ActivityB class, I sugges you move/refactor the method to another Util class or something like that.
