how do you remove the navigation bar on Android?

Question

When I listen to a YouTube video fullscreen in landscape on my Galaxy Nexus, the navigation bar on the right disapear after a few seconds (the bar which contains the "back", "home" and "recent apps" buttons ).

I want to do the same thing when a user watch a video in my app. What is the code to hide the navigation bar?

[UPDATE] Here is the bar I want to hide. Not the title bar, nor the action bar. The navigation bar. (the bar which contains the "back", "home" and "recent apps" buttons ). I also don't want to "dim" the buttons. I'm looking into removing the bar entirely (like the YouTube app does when you plan a video fullscreen in landscape mode)

Use:

view.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

Can you elaborate more? From where are you going to take the view? From the Activity? Moreover, is this flag `View.SYSTEM_UI_FLAG_HIDE_NAVIGATION` only for the ICS Android version? Or it is present as well in HoneyComb? – 2dvisio Jul 04 '12 at 11:32
@2dvisio SYSTEM_UI_FLAG_HIDE_NAVIGATION is for level 14 and up only (see http://developer.android.com/reference/android/view/View.html#SYSTEM_UI_FLAG_HIDE_NAVIGATION). And you can take any view in the screen to set this flag) – Thierry Roy Jul 04 '12 at 12:51
Thanks. It seems like for Version 3.x there's no chance of doing the same thing.. – 2dvisio Jul 04 '12 at 16:50

The last information I have is that you can use the black tape to cover it. That's the suggestion given by Chet Haase. Watch this google IO 2011 session Q&A starting at 53minutes

Youtube app also dim it, not remove it. It is called light out mode.

View v = findViewById(R.id.view_id);
v.setSystemUiVisibility(View.STATUS_BAR_HIDDEN);

SYSTEM_UI_FLAG_HIDE_NAVIGATION flag can be used on a View to hide the navigation bar until a user interaction occurs, starting from Android API 14.

You should look at here and here.

This code will hide the navigation bar until you swipe down from the status bar. It's the same method that Jetpack Joyride uses:

View decorView = getWindow().getDecorView(); 
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);

You must also have this in the activity section of your XML file:

android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen"

What you should do is set System Ui Visibility in onResume()

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);

If you wont set it sticky bar will be visible again when touch screen will be occured

I use this code to hide the navigation bar and it works perfectly for me

View v = this.getWindow().getDecorView();

v.setSystemUiVisibility(View.INVISIBLE);

Use

View view = this.getWindow().getDecorView();
view.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

While this piece of code may provide a solution to the question, it's better to add context as to why/how it works. This can help future users learn and eventually apply that knowledge to their own code. You are also likely to have positive feedback/upvotes from users, when the code is explained. – Amit Verma Feb 24 '21 at 07:46

ActionBar actionBar = getActionBar();
actionBar.hide();

That will do the trick. Also check out the HoneycombGallery example which demonstrates this working.

I want to hide the navigation bar, not the action bar. – Thierry Roy Mar 19 '12 at 16:03
Apologies. You cannot remove, but you can hide. Try this View v = findViewById(R.id.myview); v.setSystemUiVisibility(View.STATUS_BAR_HIDDEN); – Mimminito Mar 19 '12 at 16:07
This will "dim" the button - not hide them. It should be possible to remove the navigation bar since the YouTube app does it. :) – Thierry Roy Mar 19 '12 at 16:34
