transaction.replace(R.id.mylist, newFragment);
transa         


        

Answer 1

So i am also using the same fragment transaction manager and the only problem i can see with your code is that you define the TextView tv inside your onCreateView method of your newFragment class and then instantiate it as like this :

public class AboutFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.newFragment, container, false);
        TextView tv = (TextView) v.findViewById(R.id.textview);
        return v;
    }

    public void setMyString(String s) {
        tv.setText(s);
    }
}

I know it does'nt make really much sense but that is how i am running my code and it works fine :)
