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 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 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...
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

// Hide the nav bar and status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY

| View.SYSTEM_UI_FLAG_FULLSCREEN);
}

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
);
}
});
