OnMapReadyCallback { 

String [] places= {"bais city","basay","bindoy"}; 
AutoCompleteTextView textview; 

private GoogleMap mMap; 
private LatLng latLng; 
private Marker marker; 

private Toolbar category; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_maps); 
    // Obtain the SupportMapFragment and get notified when the map is ready 
     to be used. 
    SupportMapFragment mapFragment = (SupportMapFragment) 
     getSupportFragmentManager() 
      .findFragmentById(R.id.map); 
    mapFragment.getMapAsync(this); 

    category = (Toolbar) findViewById(R.id.Navbar);

Answer 1

Il ne peut pas résoudre la méthode setSupportActionBar() parce que cette méthode ne soit pas mis en œuvre FragmentActivity. Idéalement, vous devriez hériter de votre activité de AppCompatActivity, ce qui vous permettra de travailler avec la barre d'outils, ainsi qu'avec des fragments.
