I was wondering how I could hide the navigation bar in an Android application?
I know how to hide it initially, but as soon as I touch the screen it pops back up. I want to hide it the same way games like Clash of Clans hide it where the only way to make it pop up is by swiping down the notifications or by swiping where the navigation bar should be.
use immersive mode check this Immersive mode
// This snippet hides the system bars.
private void hideSystemUI() {
// Set the IMMERSIVE flag.
// Set the content to appear under the system bars so that the content
// doesn't resize when the system bars hide and show.
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE);
}
// This snippet shows the system bars. It does this by removing all the flags
// except for the ones that make the content appear under the system bars.
private void showSystemUI() {
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
Here it is in the context of the onCreate method:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
The Android docs have a good explanation of what the different flags do:
Using Immersive Full-Screen Mode
Just put this method in your activity where you want to hide status bar and navigation bar in sticky mode.
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
//This is used to hide/show 'Status Bar' & 'System Bar'. Swip bar to get it as visible.
View decorView = getWindow().getDecorView();
if (hasFocus) {
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
the easy way is adding this 2 lines after super.onCreate(savedInstanceState);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
You Can Create An Activity With The Snippet Above,And Then Add Another Windows Above The Layout:
LayoutParams layoutParameteres=new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
v.setLayoutParams(layoutParameteres);
final WindowManager.LayoutParams parameters=new WindowManager.LayoutParams(sizeX, sizeY, WindowManager.LayoutParams.TYPE_PHONE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.TRANSLUCENT);
parameters.gravity=Gravity.CENTER;
parameters.x=0;
parameters.y=0;
wm.addView(v, parameters);
Good Luck With It
In your activity's onCreate method:
this.getWindow()
.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Modify this line in the AndroidManifest.xml file
android:theme="#style/Theme.AppCompat.DayNight.NoActionBar"

In a certain activity in my app I am hiding the navigation bar since that activity is full screen. To hide the navigation bar I am using the following code:
private void hideSystemUI() {
// Enables regular immersive mode.
// For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE.
// Or for "sticky immersive," replace it with SYSTEM_UI_FLAG_IMMERSIVE_STICKY
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_IMMERSIVE
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN
);
}
This code works fine until the user swipes up the navigation bar. It then stays there. What I want is that it hides again after 2 seconds or so. Is there a way to achieve this?
I appreciate any help!
You can Use this code:
private FullScreenListener fullScreenListener = new FullScreenListener();
private void initUiFlags() {
int flags = View.SYSTEM_UI_FLAG_VISIBLE;
flags |= View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION;
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(flags);
decorView.setOnSystemUiVisibilityChangeListener(fullScreenListener);
}
Is there a way to auto hide the status bar?
I've already made the status bar hidden when activity starts and I thought it will automatically disappear after a few seconds or when the user interacts whith something else but it doesn't. And I'm still unable to make it disappear.
Here's my code :
if (Build.VERSION.SDK_INT < 16) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
I finally found the solution after reading this page.
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY // hide status bar and nav bar after a short delay, or if the user interacts with the middle of the screen
);
Try using these flags:
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_FULLSCREEN);
Google has a great write up on it here
Our base activity has a method to make it full screen.
Call this in onCreate after super.onCreate and before setContentView() like this:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
removeTitleBar();
setContentView(your_layout);
}
this is the method:
protected void removeTitleBar() {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
if (getSupportActionBar() != null)
getSupportActionBar().hide();
//Remove notification bar
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
This works for any api level as far as we support it. But we do not go as low as api 8 or so.
Sometimes 15, mostly 17+.
Hope this helps.
I am working on an application where I have to hide the bottom Navigation Panel. I have search and implement the code :
private void hideSystemUI() {
View mDecorView =getWindow().getDecorView();
// Set the IMMERSIVE flag.
// Set the content to appear under the system bars so that the content
// doesn't resize when the system bars hide and show.
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
This is working fine.
Problem : When I open any DAILOG on the screen or when the keyboard pops up, the bottom NAVIGATION PANEL pops up again.
Please suggest, how can I handle this problem.
this works,
public void FullScreencall() {
if(Build.VERSION.SDK_INT < 19) //19 or above api
View v = this.getWindow().getDecorView();
v.setSystemUiVisibility(View.GONE);
} else {
//for lower api versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);
}
}
call this method on ur oncreat.
I am trying to hide navigation bar at bottom in my app.
With following code in my onCreate I can hide it. But when I press screen or press volume buttons it comes up again.
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
How can I permanently hide navigation bar.
Add this Code In to Your onCreate() Method it will work for you But android version 4.4 or higher
View decor_View = getWindow().getDecorView();
int ui_Options = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decor_View.setSystemUiVisibility(ui_Options);
Hi I did it with using
View.SYSTEM_UI_FLAG_IMMERSIVE and
SYSTEM_UI_FLAG_HIDE_NAVIGATION flags same time.
It requires 4.4 but my version is 4.2.2.
Thats why I couldn't do it before. Thank you all for your answers and consern.
Try this,
public void FullScreencall() {
if(Build.VERSION.SDK_INT < 19) { // 19 or above API
View v = this.getWindow().getDecorView();
v.setSystemUiVisibility(View.GONE);
} else {
//For lower API versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);
}
}
Call this method on your onCreate
I want to make an activity to go into IMMERSIVE mode and hide top and buttom system bars as soon as it starts.
In developers site of android they say I should use setSystemUiVisibility() and provide SYSTEM_UI_FLAG_IMMERSIVE and SYSTEM_UI_FLAG_HIDE_NAVIGATION.
How can I do this in the OnCreate() method of the activity? I think the setSystemUiVisibility is not provided in the Activity class and it should happen in a view. Is there a workaround?
UPDATE
ok According to doorstuck I added the following lines but I dont see any changes, navigation bar and buttom buttons are still visible :
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
}
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_IMMERSIVE);
}
//Rest of activity code
Get the decor view:
getWindow().getDecorView().setSystemUiVisibility(...)
Remember that the arguments are bit flags. Only call the method above once:
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE);
Chris Banes gist shows a nice Helper Class we can use to set the immersive mode for all Versions from HoneyComb to Lollipop https://gist.github.com/chrisbanes/73de18faffca571f7292.
Update:
I tried get it from his github repo to include in my project, but i had to clone the gist files into my project and adjsut the packagename. If someone knows how to include it properly as a dependency, u r welcome to help me.
I added it in my FullScreenActivity i want to use the ImmersiveStickyMode like this:
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
final int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
SystemUiHelper uiHelper = new SystemUiHelper(this, SystemUiHelper.LEVEL_IMMERSIVE ,flags);
uiHelper.hide();
}
You can create global function to go into immersive mode like:
public static void enableImmersiveMode(final View decorView) {
decorView.setSystemUiVisibility(setSystemUiVisibility());
decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
#Override
public void onSystemUiVisibilityChange(int visibility) {
if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
decorView.setSystemUiVisibility(setSystemUiVisibility());
}
}
});
}
public static int setSystemUiVisibility() {
return View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
}
Above code will also control system UI visibility change. Hope this will help you.
Much nicer and credit to William J. Francis:
public class GameActivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
/* my code you dont need this
assets=getAssets();
sGame= new GameView(this, GAME_WIDTH, GAME_HEIGHT);
setContentView(sGame);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
*/
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
#Override
protected void onDoSomethingOtherImportantThing(){
...
}
}
Answer has already been given but here is How to utilize Immersive mode.
In your activity:
just before setContentview().......
call the method: toggleHideyBar();
Follow documentation documentation from Developer android and copy this method in your Activity.
android:immersive="true" will hide the Bottom system bars
<application>
<activity
android:name=".CarrierActivity"
android:label="#string/app_name"
android:excludeFromRecents="true"
android:immersive="true"
android:configChanges="orientation|keyboardHidden|screenSize">
<intent-filter>
<action android:name="com.example.SetupWiz.SUW_CARRIER"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
