Question

I have a class called people that has its own name, id etc…
I have a full list of people in an array list public ArrayList<people> pList;
When I click on some names I want to add the people in pList to public ArrayList<people> followList; Doing followList.add(pList.get(position)) doesn’t work. What is the proper way to do this.

Also, on another click I would like to remove the particular object from the followList so I tried doing followList.remove(pList.get(position)) but obviously it doesn’t work as well.

Im basically trying to have a list of people from the original list.

Answer 1

The followList seems to be not initialized. You should call initialize it with new ArrayList<people>() before adding to or removing from it.
