Hiding SupportActionBar in Fragment

Question

I want to hide my MainActiviy Toolbar in my fragment, i'm using:

getActivity().findViewById(R.id.appToolbar).setVisibility(View.GONE);

and:

((AppCompatActivity) getActivity()).getSupportActionBar().hide();

and is not working. My fragment has his own Toolbar, and is already been showed, but my Activity Toolbar is being showed too. What am i doing wrong? I just want to show my fragment ToolBar

you should use the activity which loads the Fragment, (which has actionBar), for example if you are loading fragment in HomeActivity. try ((HomeActivity) getActivity().getSupportActionBar().hide(); — aadi53, Nov 12 '15 at 21:24
is not working... same issue :-( . I try this code in other fragment and it works, the difference between one fragment and other is that when i replace it, i'm adding one into backstack and the other is not being added... (the toolbar disappear when the fragment is not added to th backstack) — JaviSanchezG, Nov 12 '15 at 21:33

Actually the issue was that i am adding the fragment to the backstack, and we cannot delete or hide the SupportActionBar if we have "something" in the backstack, i delete the addToBackStack() method in my project and i am already deleting my supportBar from my Fragment — JaviSanchezG, Nov 13 '15 at 21:19

The ActionBar is owned by the Activity not by the Fragment, so you need to call .hide() method on this Activity, try in this way:

getActivity.getSupportActionBar().hide();

getActivity().getSupportActionBar().hide(); cannot be resolved... i have to use ((AppCompatActivity) getActivity()).getSupportActionBar().hide(); – JaviSanchezG Nov 12 '15 at 21:37

If you use AppCompat toolbar. Solution:

Must hide Actionbar before using AppCompat Toolbar by apply suitable NoActionBar theme following: this or this
Setup AppCompat toolbar to activity using this guide:

r

Toolbar toolbar = (Toolbar) findViewById(R.id.appToolbar);
setSupportActionBar(toolbar);//replace ActionBar with toolbar
findViewById(R.id.appToolbar).setVisibility(View.GONE);//hide if you want

You must replace `Actionbar` before using AppCompat Toolbar – T D Nguyen Nov 13 '15 at 01:41
