Answer 1

now I understand your problem. you need to use interface for join recyclerview item and activity. you must define an interface class like below:

public interface IViewClick {
    public void onClickButtonAdd();
}

add this parameter to your adapter class:

private IViewClick mListener;

and initialize it in constructor with value that get from inputs. when user click on PLUS button, you send event to activity by this line:

 mListener.onClickButtonAdd();

in your activity class you must implements IViewClick interface and add your code there, like this:

@Override
    public void onClickButtonAdd() {
         ///  TODO every thing that you want.
         /// change your toolbar values.
    }

it is not good solution for you.

RecyclerView.ViewHolder holder = mRecyclerView.findViewHolderForItemId(mAdapter.getItemId(i));
