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'm trying to implement a fullscreen mode, but for Android 4.4 and up, it shows a blank space there:
BEFORE immersive mode(fullscreen)
and AFTER the toggleFullScreen(false);
as you can see, its doesn't remove it. Here's the code that I'm using to toggle it:
public void toggleFullscreen(boolean fs) {
if (Build.VERSION.SDK_INT >= 11) {
// The UI options currently enabled are represented by a bitfield.
// getSystemUiVisibility() gives us that bitfield.
int uiOptions = this.getWindow().getDecorView().getSystemUiVisibility();
int newUiOptions = uiOptions;
boolean isImmersiveModeEnabled =
((uiOptions | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) == uiOptions);
if (isImmersiveModeEnabled) {
Log.i(getPackageName(), "Turning immersive mode mode off. ");
} else {
Log.i(getPackageName(), "Turning immersive mode mode on.");
}
// Navigation bar hiding: Backwards compatible to ICS.
if (Build.VERSION.SDK_INT >= 14) {
newUiOptions ^= View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
}
// Status bar hiding: Backwards compatible to Jellybean
if (Build.VERSION.SDK_INT >= 16) {
newUiOptions ^= View.SYSTEM_UI_FLAG_FULLSCREEN;
}
// Immersive mode: Backward compatible to KitKat.
// Note that this flag doesn't do anything by itself, it only augments the behavior
// of HIDE_NAVIGATION and FLAG_FULLSCREEN. For the purposes of this sample
// all three flags are being toggled together.
// Note that there are two immersive mode UI flags, one of which is referred to as "sticky".
// Sticky immersive mode differs in that it makes the navigation and status bars
// semi-transparent, and the UI flag does not get cleared when the user interacts with
// the screen.
if (Build.VERSION.SDK_INT >= 18) {
newUiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
}
getWindow().getDecorView().setSystemUiVisibility(newUiOptions);
} else {
// for android pre 11
WindowManager.LayoutParams attrs = getWindow().getAttributes();
if (fs) {
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
} else {
attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
}
this.getWindow().setAttributes(attrs);
}
try {
// hide actionbar
if
(this instanceof AppCompatActivity) {
if (fs) getSupportActionBar().hide();
else getSupportActionBar().show();
} else if
(Build.VERSION.SDK_INT >= 11) {
if (fs) getActionBar().hide();
else getActionBar().show();
}
} catch (Exception e) {
e.printStackTrace();
}
}
Please check that you don't have android:fitsSystemWindows="true" in your layout.
At least it solved my case - I had fitsSystemWindows on FrameLayout.
I'm new here so I can't comment, but wanted to add something that got me so frustrated me about the above solution. I kept checking my activities and its fragments for android:fitsSystemWindows="true" and it was definitely not there, yet I kept having a gap at the bottom! I was going nuts! It couldn't be this hard to fix this simple thing!
Turns out it also showed up in the Navigation Drawer I added...so be sure to check all your XML!
Try this:
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
var viewParent = view
while (viewParent is View) {
viewParent.fitsSystemWindows = false
viewParent.setOnApplyWindowInsetsListener { _, insets -> insets }
viewParent = viewParent.parent as View?
}
}
What does this do? DialogFragment#onActivityCreated() calls Dialog#setContentView(), which wraps the Dialog's view in a private 'wrapInBottomSheet'. In order to set the proper flags of those wrapper views, we want to set the flags after they are wrapped, e.g. after super.onActivityCreated()
Also watch this talk for info on fitsSystemWindows and window insets.
Just change the android:fitsSystemWindows="true" to android:fitsSystemWindows="false" in your layout file.
You need to add this flag to your view View.SYSTEM_UI_FLAG_LAYOUT_STABLE. Try it like this
// 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);
}
I want to hide navigation bar permanently in my activity(not whole system ui).
now i'm using this piece of code
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
It hides the bar but when user touches the screen it showing again. is there any way to hide it permanently until activity onStop();
Snippets:
FullScreenFragment.java
HideNavigationBarComponent.java
This is for Android 4.4+
Try out immersive mode https://developer.android.com/training/system-ui/immersive.html
Fast snippet (for an Activity class):
private int currentApiVersion;
#Override
#SuppressLint("NewApi")
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
currentApiVersion = android.os.Build.VERSION.SDK_INT;
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;
// This work only for android 4.4+
if(currentApiVersion >= Build.VERSION_CODES.KITKAT)
{
getWindow().getDecorView().setSystemUiVisibility(flags);
// Code below is to handle presses of Volume up or Volume down.
// Without this, after pressing volume buttons, the navigation bar will
// show up and won't hide
final View decorView = getWindow().getDecorView();
decorView
.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener()
{
#Override
public void onSystemUiVisibilityChange(int visibility)
{
if((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0)
{
decorView.setSystemUiVisibility(flags);
}
}
});
}
}
#SuppressLint("NewApi")
#Override
public void onWindowFocusChanged(boolean hasFocus)
{
super.onWindowFocusChanged(hasFocus);
if(currentApiVersion >= Build.VERSION_CODES.KITKAT && hasFocus)
{
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);
}
}
If you have problems when you press Volume up or Volume down that your navigation bar show. I added code in onCreate see setOnSystemUiVisibilityChangeListener
Here is another related question:
Immersive mode navigation becomes sticky after volume press or minimise-restore
Do this.
public void FullScreencall() {
if(Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) { // lower api
View v = this.getWindow().getDecorView();
v.setSystemUiVisibility(View.GONE);
} else if(Build.VERSION.SDK_INT >= 19) {
//for new api versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);
}
}
This works 100% and you can do same for lower API versions, even if it's a late answer I hope it will helps someone else.
If you want this to be permanent, just call FullScreencall() inside your onResume() method.
For people looking at a simpler solution, I think you can just have this one line of code in
onStart()
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
It's called Immersive mode. You may look at the official documentation for other possibilities.
The other answers mostly use the flags for setSystemUiVisibility() method in View. However, this API is deprecated since Android 11. Check my article about modifying the system UI visibility for more information. The article also explains how to handle the cutouts properly or how to listen to the visibility changes.
Here are code snippets for showing / hiding system bars with the new API as well as the deprecated one for backward compatibility:
/**
* Hides the system bars and makes the Activity "fullscreen". If this should be the default
* state it should be called from [Activity.onWindowFocusChanged] if hasFocus is true.
* It is also recommended to take care of cutout areas. The default behavior is that the app shows
* in the cutout area in portrait mode if not in fullscreen mode. This can cause "jumping" if the
* user swipes a system bar to show it. It is recommended to set [WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER],
* call [showBelowCutout] from [Activity.onCreate]
* (see [Android Developers article about cutouts](https://developer.android.com/guide/topics/display-cutout#never_render_content_in_the_display_cutout_area)).
* #see showSystemUI

In Tablets running Android 4+, it is not possible to hide the System / Navigation Bar.
From documentation :
The SYSTEM_UI_FLAG_HIDE_NAVIGATION is a new flag that requests the
navigation bar hide completely. Be aware that this works only for the
navigation bar used by some handsets (it does not hide the system bar
on tablets).
According to Android Developer site
I think you cant(as far as i know) hide navigation bar permanently..
However you can do one trick. Its a trick mind you.
Just when the navigation bar shows up when user touches the screen. Immediately hide it again.
Its fun.
Check this.
void setNavVisibility(boolean visible) {
int newVis = SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| SYSTEM_UI_FLAG_LAYOUT_STABLE;
if (!visible) {
newVis |= SYSTEM_UI_FLAG_LOW_PROFILE | SYSTEM_UI_FLAG_FULLSCREEN
| SYSTEM_UI_FLAG_HIDE_NAVIGATION;
}
// If we are now visible, schedule a timer for us to go invisible.
if (visible) {
Handler h = getHandler();
if (h != null) {
h.removeCallbacks(mNavHider);
if (!mMenusOpen && !mPaused) {
// If the menus are open or play is paused, we will not auto-hide.
h.postDelayed(mNavHider, 1500);
}
}
}
// Set the new desired visibility.
setSystemUiVisibility(newVis);
mTitleView.setVisibility(visible ? VISIBLE : INVISIBLE);
mPlayButton.setVisibility(visible ? VISIBLE : INVISIBLE);
mSeekView.setVisibility(visible ? VISIBLE : INVISIBLE);
}
See this for more information on this ..
Hide System Bar in Tablets
It's my solution:
First, define boolean that indicate if navigation bar is visible or not.
boolean navigationBarVisibility = true //because it's visible when activity is created
Second create method that hide navigation bar.
private void setNavigationBarVisibility(boolean visibility){
if(visibility){
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
navigationBarVisibility = false;
}
else
navigationBarVisibility = true;
}
By default, if you click to activity after hide navigation bar, navigation bar will be visible. So we got it's state if it visible we will hide it.
Now set OnClickListener to your view. I use a surfaceview so for me:
playerSurface.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setNavigationBarVisibility(navigationBarVisibility);
}
});
Also, we must call this method when activity is launched. Because we want hide it at the beginning.
setNavigationBarVisibility(navigationBarVisibility);
I think the blow code will help you, and add those code before setContentView()
getWindow().setFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS, WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
Add those code behind setContentView()
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
Its a security issue:
https://stackoverflow.com/a/12605313/1303691
therefore its not possible to hide the Navigation on a tablet permanently with one single call at the beginning of the view creation. It will be hidden, but it will pop up when touching the Screen. So just the second touch to your screen can cause a onClickEvent on your layout. Therefore you need to intercept this call, but i haven't managed it yet, i will update my answer when i found it out. Or do you now the answer already?
Try this:
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
I think this code will resolve your issue. Copy and paste this code on your MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View decorView = getWindow().getDecorView();
decorView.setOnSystemUiVisibilityChangeListener
(new View.OnSystemUiVisibilityChangeListener() {
#Override
public void onSystemUiVisibilityChange(int visibility) {
if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
hideNavigationBar();
}
}
});
}
private void hideNavigationBar() {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
It will works on Android-10. I hope it will helps.
You can hide Navigator Bar using this:
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
View decorView = getWindow().getDecorView();
if(hasFocus){
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|
View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
);
}
}
This way you can hide Navigation Buttons without hiding Status bar
Here is the hide and show system UI for android 11 and Below. But below from Android its deprecated.
private fun hideSystemUI() {

controller.hide(WindowInsetsCompat.Type.systemBars())
controller.systemBarsBehavior =

}
}
private fun showSystemUI() {
WindowCompat.setDecorFitsSystemWindows(window, true)
WindowInsetsControllerCompat(
window,
drawerLayoutID
).show(WindowInsetsCompat.Type.systemBars())
}

val decorView: View = window.decorView
val uiOptions = decorView.systemUiVisibility
var newUiOptions = uiOptions
newUiOptions = newUiOptions or View.SYSTEM_UI_FLAG_LOW_PROFILE

newUiOptions = newUiOptions or View.SYSTEM_UI_FLAG_IMMERSIVE
newUiOptions = newUiOptions or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
decorView.systemUiVisibility = newUiOptions
}
private fun showSystemUIBelowR() {
val decorView: View = window.decorView
val uiOptions = decorView.systemUiVisibility
var newUiOptions = uiOptions
newUiOptions = newUiOptions and View.SYSTEM_UI_FLAG_LOW_PROFILE.inv()
newUiOptions = newUiOptions and View.SYSTEM_UI_FLAG_FULLSCREEN.inv()
newUiOptions = newUiOptions and View.SYSTEM_UI_FLAG_HIDE_NAVIGATION.inv()
newUiOptions = newUiOptions and View.SYSTEM_UI_FLAG_IMMERSIVE.inv()
newUiOptions = newUiOptions and View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY.inv()
decorView.systemUiVisibility = newUiOptions
}
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 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 see this link:
http://developer.android.com/training/system-ui/status.html
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
);
}
});
