Custom ListView open another custom ListView

I'm trying to create app(workout plan) which use a lot of listView. It means: When I click "Create Exercise" -> new name of exercise is created in listView. One ListView for every names of exercises. ( I have this ). But when I click on every item of this listView I want to create new series for each item. But when I click "Create new series" in first item and when I click the same but in a second item it's created in one listView.

But I would like to save this to another listView for every item. Is it possible? As I think at now, every item should have own listView.

Actually, my question is: Why are every series created in one ListView? Because the is one common activity for create series?

Could someone help me to find a solution for my case?

In this photo I show my idea.
