Removing Action Bar completely from Fragment

Question

I am currently trying to change the way an application looks.

The application uses 3 fragments that can be called base on network state changes. The fragments are all set to landscape, this leads the action bar to be a huge portion of the screen. I am trying to find a way to removed the action bar completely and allow the layout to expand to the entirety of the screen.

I have already tried things like:

getActionBar().hide();

Theme Changes

setSystemUiVisibility();

These option will either create a large bar across the screen where it should be or just display the Action bar anyways.

I assume this is something with the way fragments work that I just do not understand.

If you want to completely remove the ActionBar (AppBar) completely from your App, then follow these steps:

• Go to your AndroidManifest.xml
• Edit this line: android:theme="@style/{theme}"> to android:theme="@style/Theme.AppCompat.Light.NoActionBar"> or anything that ends with NoActionBar.

And if you want to remove the ActionBar just from your Fragment, then add next code in the onCreateView() of the Fragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    // create ContextThemeWrapper from the original Activity Context with the custom theme
    final Context contextThemeWrapper = new ContextThemeWrapper(getActivity(), R.style.yourCustomTheme);

    // clone the inflater using the ContextThemeWrapper
    LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper);

    // inflate the layout using the cloned inflater, not default inflater
    return localInflater.inflate(R.layout.yourLayout, container, false);
}

Or if you want to remove the ActionBar from an Activity, add this one line of code to the onCreate() method of the Activity.

setTheme(R.style.{your style}

Remember

• The {style} should end with NoActionBar

• And most importantly, add the code before these two lines of code (add it to the top of the method):

  super.onCreate(savedInstanceState);
  setContentView(R.layout.{your layout});
  

Hope this answer helped!
