How to update fragment content from activity (viewpager)?

Question

I have a simple viewPager with two fragments. Each fragment contains a TextView. I would like to be able to update the text of the current textView displayed from the activi

Answer 1

@Override
    public int getItemPosition(Object object) {
    XXXFragment fragment = (XXXFragment) object;
        if(…condition){
    fragment.refresh(…);
    }
        return super.getItemPosition(object);
    }

override the above. when you call notifyDataSetChanged(), the above method's triggered. do your refresh as you can.
