Question

am currently messing around with DialogFragment to learn to use it. I assumed that compared to onCreateView(), onCreate() can do this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    testTextView.setText("SUCCESS!"); //ERROR HERE
}

But I am wrong. Not sure why its not working. The error goes away when I comment out testTextView.setText("Success!"); The error is a NullPointerException, and then it just flags line 39 which is where the offending line of code is. Any clarifications much appreciated.

Answer 1

where you initalzed testTextView. ? you should do that………

and also as per fragment life cycle

onAttach(Activity)-->onCreate(Bundle) -->onCreateView(LayoutInflater, ViewGroup, Bundle)->onActivityCreated(Bundle)-->onStart() 

so you should handle this work either in onCreateView or after this…
