getActionBar() is undefined

android, android-actionbar, java

Solution

As far as I know, you need to ask the `Activity` (to which the `Fragment` has been attached) for the `ActionBar`:

ActionBar actionBar = getActivity().getActionBar();

Or if you're using the support library and/or ActionBarSherlock:

ActionBar actionBar = getFragmentActivity().getSupportActionBar();

Fragments don't define a `getActionBar()` method, hence the error message.

Problem

I want to add a ActionBar to my Fragment class, but I keep getting errors. This is my class: ``` public class TaskDetailFragment extends Fragment { public static final String ARG_ITEM_ID = "item_id"; MyTasks.taskItem mItem; public TaskDetailFragment() { } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (getArguments().containsKey(ARG_ITEM_ID)) { mItem = MyTasks.ITEM_MAP.get(getArguments().getString(ARG_ITEM_ID)); } } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_task_detail, container, false); ActionBar actionBar = getActionBar(); actionBar.show(); if (mItem != null) { //Add TexViews ((TextView) rootView.findViewById(R.id.in_Name)) .setText(MyTasks.customers[(Integer.parseInt(mItem.id))][1]); ((TextView) rootView.findViewById(R.id.in_Address)) .setText(MyTasks.customers[(Integer.parseInt(mItem.id))][3] + " " + MyTasks.customers[(Integer.parseInt(mItem.id))][2]); } return rootView; } } ``` This is my error: The method getActionBar() is undefined for the type TaskDetailFragment
