Using Toolbar with Fragments

Fragments don’t have such method setSupportActionBar(). ActionBar is a property of Activity, so to set your toolbar as the actionBar, your activity should extend from ActionBarActivity and then you can call in your Fragment:

 ((ActionBarActivity)getActivity()).setSupportActionBar(mToolbar);

UPDATE

If you’re using AppCompatActivity :

 ((AppCompatActivity)getActivity()).setSupportActionBar(mToolbar);
