Set toolbar title
Solution 1
Change it to
((AppCompatActivity)getActivity()).getSupportActionBar().setTitle("Home");
You needed to tell the activity it is an AppCompatActivity
.
Then you use getActivity()
to get the main activity since you are in a fragment.
Then just set the title as usual.
Solution 2
In kotlin
(activity as? AppCompatActivity)?.supportActionBar?.title = "title"
Edit:
Added null safe operator ?
to avoid NullPointer
in case ActionBar not available
Solution 3
Actually you can just do the following:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
getActivity().setTitle("My title");
}
I make the change in onActivityCreated
because the Activity may have not been fully initialized yet in onCreateView
. In onActivityCreated
there is no risk of getting a NullPointerException
.
NOTE: I am using an AppCompatActivity
with a Toolbar
and v4 Fragments
associated to it.
Solution 4
Kotlin set title from resources
Activity:
setTitle(R.string.some_title)
Fragment:
activity?.setTitle(R.string.some_title)
Solution 5
The best and easiest way to do this, is to go to Android Manifest and change the label
within the Activity
section. This is what's responsible for labelling the Activity along the toolbar. This saves you writing lines of code in the class file.

I am trying to set my toolbar title like so:
public class StatisticsPage extends Fragment { public StatisticsPage(){} private FragmentTabHost mTabHost; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.statistics_pagelayout, container, false); Spinner spinner = (Spinner) rootView.findViewById(R.id.statsSpin); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getActivity(), R.array.statspage, R.layout.dropdown_item); spinner.setAdapter(adapter); getSupportActionBar().setTitle("My title"); spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { switch (position) { case 0: break; case 1: // do whatever stuff you wanna do here Fragment Fragment_one; FragmentManager man= getActivity().getSupportFragmentManager(); FragmentTransaction tran = man.beginTransaction(); Fragment_one = new BreweryStatistics(); tran.replace(R.id.main, Fragment_one);//tran. tran.addToBackStack(null); tran.commit(); break; case 2: Fragment Fragment_two; FragmentManager mantwo= getActivity().getSupportFragmentManager(); FragmentTransaction trantwo = mantwo.beginTransaction(); Fragment_two = new StyleStatistics(); trantwo.replace(R.id.main, Fragment_two);//tran. trantwo.addToBackStack(null); trantwo.commit(); break; case 3: Fragment Fragment_three; FragmentManager manthree= getActivity().getSupportFragmentManager(); FragmentTransaction tranthree = manthree.beginTransaction(); Fragment_three = new TasteStatisticsPage(); tranthree.replace(R.id.main, Fragment_three);//tran. tranthree.addToBackStack(null); tranthree.commit(); break; } } @Override public void onNothingSelected(AdapterView<?> parentView) { // your code here } }); SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity()); String userName = prefs.getString("userName", null); String userID = prefs.getString("userID", null); String url = "myURL"; String userURLComp = "u=" + userID; url = url + userURLComp ; new getBasicStats(getActivity()).execute(url); return rootView; } }
Basically this line in the above code does not work in the fragment:
getSupportActionBar().setTitle("My title");
Also How can I stop my app title from showing up in the app bar? I would also like to make the title white when I can set it.
