Remove ActionBar in fragment

I have some troubles trying to remove a toolbar in a specific fragment, i have this code in onCreateView fragment method:

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_login,container,false);
    mValidator = new Validator(this);
    mValidator.setValidationListener(this);
    mFbHelper = new 
    mGHelper = new GoogleHelper(this, null, this);

    ((DrawerUtil) getActivity()).setDrawerLocked(true);
    ((AppCompatActivity) getActivity()).getSupportActionBar().hide();
    initViews(view);
    return view;
}

I can hide the ActionBar, but the idea is to remove the ActionBar to use properly a logo, im using this code: ((AppCompatActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(state); but it doesnt work.enter image description here Any ideas?

For a specific fragment you can use :

override fun onStart() {
        super.onStart()
        (activity as AppCompatActivity).supportActionBar!!.hide()
    }

    override fun onStop() {
        super.onStop()
        (activity as AppCompatActivity).supportActionBar!!.show()
    }


    override fun onResume() {
        super.onResume()
        (activity as AppCompatActivity).supportActionBar!!.hide()
    }

for kotlin, using 

import android.support.v7.app.AppCompatActivity

Try

 override fun onStart() {
        super.onStart()
        //hide action bar from splash screen
        (activity as AppCompatActivity).supportActionBar!!.hide()
 }

in the specific fragment(s, and 

            supportActionBar!!.hide()

in the Activity/Activities.

Note: do not forget to replace "hide()" by "show()" when you want the ActionBar to be visible again.

It may be a little late, but this may save the next OP some minutes of searching. This is what worked for me @Johan Sanchez . Assuming that you have declared the theme to NoActionBar in your manifest but a blank space remains, its probably your XML files..

In my main_activity.xml file is a fragment placeholder that will be replaced by the respective fragment xml files... inside it is a layout_margintop attribute. Remove it

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="simiyu.com.smallheaven.MainActivity">
<FrameLayout
    android:id="@+id/flContent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="?attr/actionBarSize"/>

</android.support.design.widget.CoordinatorLayout>

The result should then be as 

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="simiyu.com.smallheaven.MainActivity">
<FrameLayout
    android:id="@+id/flContent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="?attr/actionBarSize"/>

</android.support.design.widget.CoordinatorLayout>
enter code here

For your login activity use 

<style name="BaseTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
   <item name="windowNoTitle">true</item>
   <item name="windowActionBar">false</item>
</style>

this will remove the default ActionBar provided by android.So attach your fragment to this activity and there will be no action bar in your fragment too.

For other activities if you need a ActionBar you can use the same theme and add Toolbar as actionBar to youer activity.

If you do not want ActionBar use theme

parent="@style/Theme.AppCompat.Light.NoActionBar"

If you want ActionBar use theme

parent="@style/Theme.AppCompat.Light.DarkActionBar" or

parent="@style/Theme.AppCompat.Dark.LightActionBar"

If you use light or dark ActionBar theme you will get a default ActionBar.Again if you want to hide this u can do this 

getActivity().getSupportActionBar().hide();    // in Fragment

getSupportActionBar().hide();                  // in Activity
