Answer 1

Unless your Fragment is a static inner class, you can set a custom title to the ActionBar.

To do this, while using a custom layout, in your Fragment, call getActivity().setTitle(YOUR_TITLE) .

The reason you call setTitle is because you're calling getTitle as the title of your ActionBar. This returns the title for that Activity.

If you don't want to get call getTitle , then you'll need to create a public method that sets the text of your TextView in the Activity that hosts the Fragment.

In your activity you need to enter this code:

public void setActionBarTitle(String title){
    YOUR_CUSTOM_ACTION_BAR_TITLE.setText(title);
}

Also, include this code in your fragment:

((MainFragmentActivity) getActivity().getApplicationContext()).setActionBarTitle(YOUR_TITLE);

2015 Update:

It seems that last year, Android have updated the way this is done. If you are building for later APIs, you need to use this:

In your fragment:

public class UpdateActionBarTitleFragment extends Fragment {
private OnFragmentInteractionListener mListener;

    public UpdateActionBarTitleFragment() {
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        if (mListener != null) {
            mListener.onFragmentInteraction("Custom Title");
        }
        return inflater.inflate(R.layout.fragment_with_action_bar, container, false);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try {
            mListener = (OnFragmentInteractionListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " needs to use OnFragmentInteractionListener");
        }
    }

    @Override
    public void onDetach() {
        super.onDetach();
        mListener = null;
    }

    public interface OnFragmentInteractionListener {
        public void onFragmentInteraction(String title);
    }
}

In your activity:

public class UpdateActionBarTitleActivity extends ActionBarActivity implements UpdateActionBarTitleFragment.OnFragmentInteractionListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_with_action_bar);
    }

    @Override
    public void onFragmentInteraction(String title) {
        getSupportActionBar().setTitle(title);
   }
}

Hope this helps :)

Answer 2

Could you please try to put below lines to onCreate:

    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setTitle("Title");

Answer 3

Try following code, hope that helps

setActionBar(toolbar);
getActionBar().setDisplayShowTitleEnabled(true);
getActionBar().setTitle("Your Title");

Answer 4

I think this logic help you

(First way):

In your fragment call add following code

getActivity().setTitle("your title");

(Second way): call any type of function of your parent Activity or fragment class

YourActivity mActiviy = (YourActivity) getActivity();
mActivity.yourActivityFunction(yourParameters);
