问题
When I try to start a fragment from an activity class I keep getting a
No view found for id 0x7f0900ad frame_container2 error. The code then crashes after progress dialog shows up and moves to the fragment I'm trying to starting.
When it crashes it gives me an error like this:
05-23 12:02:32.271: E/FragmentManager(4295): No view found for id 0x7f0900ad (com.fitserv.androidapp:id/frame_container2) for fragment UserWorkoutPlanFragment{4165dbc8 #0 id=0x7f0900ad}

Does anyone have any idea how I could resolve this issue?
回答1:
You don't need to extend ListFragment in:
public class UserWorkoutPlanFragment extends ListFragment...
If you do extend ListFragment, you have to reference xml layout containing a ListView element. So the code in onCreateView pointing to an xml layout:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.user_workoutplan, container, false);
Notes:
- Layout
user_workoutplanmust include a ListView element. Otherwise, extending ListFragment is useless. I think that is the problem. - Again, another solution is to not extend ListFragment.
Good luck in this project. The existing code such at is now is not easy to understand. And there are codes that I think is suspect or should change.
