I want to hide status bar in my status bar and this is how I do it:
if (Build.VERSION.SDK_INT < 16) {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
} else {
View decorView = activity.getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN
decorView.setSystemUiVisibility(uiOptions);
}
}
The issue is when the soft keyboard becomes visible (typing in an EditText), the status bar comes back.
If you want to do on .java, just code:
if (Build.VERSION.SDK_INT < 16) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
but if you want to hide status bar on xml, just code:
<application
...
android:theme="#android:style/Theme.Holo.NoActionBar.Fullscreen" >
...
</application>
Take a look at http://developer.android.com/intl/es/training/system-ui/status.html for more information...

Is it possible to hide the navbar without hiding the status bar?
I've tried this in my styles's xml
<item name="android:windowFullscreen">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
and I hide de navbar like this in the activity
val decorView = window.decorView
val uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or View.SYSTEM_UI_FLAG_FULLSCREEN or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
decorView.systemUiVisibility = uiOptions
Thank you!!
Edit:
fun hideNavigationStatusBar(activity: Activity) {
activity.window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
val decorView = activity.window.decorView
val uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or View.SYSTEM_UI_FLAG_FULLSCREEN or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
decorView.systemUiVisibility = uiOptions
}
fun translucidNavigationBar(activity: Activity) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
val w = activity.window
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}
}
I can hide status and navigation bar with the first method and keep the status with a translucent navigation with the second, but still I can't reach to keep the status and completely hide the navigation bar.
The easiest way to solve this is in two parts, removing the navbar and then making the status bar transparent.
1 - Removing the navbar
To remove the navbar, create a new style on the styles.xml file under the values folder that inherits from Theme.AppCompat.Light.NoActionBar.
Then on the manifest.xml file change the theme of the Activity to your custom style.
With this the navbar will be removed, but the status bar will still be grayed out.
2 - Making the status bar transparent
You can follow this tutorial to make the status bar transparent: Transparent Status Bar
Or just add the following to the onCreate method of your Activity:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
With this you can expect an App style similar to the one in the next picture:
3 - Removing the status bar completely
To hide the status bar completely, add this on your onCreate method:
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
You can read more on this at Hiding the status bar
Result:
4 - Removing the navigation Bar
You can find a solution to this at the Android Developer site Hiding the navigation bar
Basically just add this to your onCreate:
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
You can use this method:
private void setTransparentStatusBar(Activity activity) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
activity.getWindow().setStatusBarColor(Color.TRANSPARENT);
} else {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
}
I use SYSTEM_UI_FLAG_FULLSCREEN to hide status bar, code like this(sdk > 16):
Decorview decorview = getWindow().getDecorview();
decorview.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
However, it works on some Android phones but fails on others like below:
What is wrong with the white satus bar? Why is it not hidden?
ps: The style is ok, just a normal one, no fitwindowsystem, no immersive.
As mentioned in the Android Docs, you can hide the statusBar like this in SDK < 16 i.e Android version lower than Jellybean :
if (Build.VERSION.SDK_INT < 16) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
call this in your onCreate method, before you call setContentView.
and for SDK above 16 use the following code :
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();
1.If the Android version is lower than Jellybean, use this call to hide.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (Build.VERSION.SDK_INT < 16) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
setContentView(R.layout.activity_main);
}
2.Code to hide the Status Bar on 16 and Higher your Code works.
Decorview decorview = getWindow().getDecorview();
decorview.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
Note : Remember that you should never show the action bar if the status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();
3.if the status bar should always remain hidden in your app setting an activity theme in your app's manifest file.
<application
...
android:theme="#android:style/Theme.Holo.NoActionBar.Fullscreen" >
...
</application>
Just it, I have found how to hide title bar but I didnt find how hide / show the status bar pressing a button fr example. It is possible? thanks!
For poeple whose show part is not working , You can try following code
Show Status Bar
if (Build.VERSION.SDK_INT < 16) {
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
// show the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_VISIBLE;
decorView.setSystemUiVisibility(uiOptions);
}
To hide a status Bar
Use this code in your Activity
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Change Application theme in Manifest file as below
android:theme="#android:style/Theme.Black.NoTitleBar"
Reference - https://developer.android.com/training/system-ui/immersive.html
// 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);
}
Although action bar is overlayed with the status bar.
I am trying to create a button where I can hide or show the status bar on my tablet.
I've put in the onCreate
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
and in the buttons
show:
WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);
hide:
WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);
Any hints/tipps?
//edit
I've looked at this hint here: http://android.serverbox.ch/?p=306
and changed my code like this:
private void hideStatusBar() throws IOException, InterruptedException {
Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 79 s16 com.android.systemui"});
proc.waitFor();
}
private void showStatusBar() throws IOException, InterruptedException {
Process proc = Runtime.getRuntime().exec(new String[]{"am","startservice","-n","com.android.systemui/.SystemUIService"});
proc.waitFor();
}
So if I click on my buttons an the methods are called I can see that something is happening because the app is waiting some seconds.
I also looked into LockCat and see that something is happening.

Do you have the fullscreen theme set in the manifest?
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
I don't think you'll be able to go fullscreen without this.
I would use the following to add and remove the fullscreen flag:
// Hide status bar
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
// Show status bar
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
For Some People, Showing status bar by clearing FLAG_FULLSCREEN may not work,
Here is the solution that worked for me, (Documentation) (Flag Reference)
Hide Status Bar
// Hide Status Bar
if (Build.VERSION.SDK_INT < 16) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
// Hide Status Bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
Show Status Bar
if (Build.VERSION.SDK_INT < 16) {
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
// Show Status Bar.
int uiOptions = View.SYSTEM_UI_FLAG_VISIBLE;
decorView.setSystemUiVisibility(uiOptions);
}
used for kolin in android
for hide status bar in kolin no need to used semicolon(;) at the end of the line
window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)
in android using java language for hid status bar
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
I know its a very old question, but just in case anyone lands here looking for the newest supported way to hide status bar on the go programmatically, you can do it as follows:
window.insetsController?.hide(WindowInsets.Type.statusBars())
and to show it again:
window.insetsController?.show(WindowInsets.Type.statusBars())
I've tried so many things.
Finally, It is the most suitable code to hide and show full screen mode.
private fun hideSystemUi() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
window.setDecorFitsSystemWindows(true)
} else {
// hide status bar
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
window.decorView.systemUiVisibility =
View.SYSTEM_UI_FLAG_IMMERSIVE or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
}
}
private fun showSystemUi() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
window.setDecorFitsSystemWindows(false)
} else {
// Show status bar
window.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
window.decorView.systemUiVisibility = SYSTEM_UI_FLAG_LAYOUT_STABLE
}
}
It Implemented it in this app : Android Breakdown.
Go to Videos(Bottom Bar) > Play Any Video > Toggle Fullscreen
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//hide status bar
requestWindowFeature( Window.FEATURE_NO_TITLE );
getWindow().setFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN );
setContentView(R.layout.activity_main);
}
For Kotlin users
TO SHOW
activity?.window?.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)
TO HIDE
activity?.window?.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)
with this method, using SYSTEM_UI_FLAG_IMMERSIVE_STICKY the full screen come back with one tap without any implementation. Just copy past this method below and call it where you want in your activity.
More details here
private void hideSystemUI() {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_IMMERSIVE
// Set the content to appear under the system bars so that the
// content doesn't resize when the system bars hide and show.
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
// Hide the nav bar and status bar

i am using this method to hide status bar :
public static void hideStatusBar(Activity activity) {
if (Build.VERSION.SDK_INT < 16) {
activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else {
View decorView = activity.getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
}
this works fine but when i start video i have notice the status bar is visible again , after some test on my code i have realized that the status bar i visible after i add the MediaController .
how can i keep my full screen and still using MediaController ?
this is how i add the MediaController
mMediaController = new MediaController(getContext());
mMediaController.setAnchorView(this);
setMediaController(mMediaController);
use:
<application
...
android:theme="#android:style/Theme.Holo.NoActionBar.Fullscreen" >
...
</application>
or
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();

and this link:
How to hide status bar in Android
Yes, the videoView can bring back the status bar. Not sure what the behind principle is. While you can resolve it by setting a setOnSystemUiVisibilityChangeListener, Something like:
getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
#Override
public void onSystemUiVisibilityChange(int visibility) {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
);
}
});
