I want my layout to start below the status bar and expand till the end of screen . Navigation bar should be hidden .
For this i have used this theme :
<style name="AppTheme.NoActionbarThemeDefaultStatusColor" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
</style
for my actiivity.
And i also use below code in the oncreate method of my activity.
window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
or View.SYSTEM_UI_FLAG_LOW_PROFILE)
Everything is fine i.e status bar is there , no navigation bar is there .
But the layout's top part is hidden below status bar . I want layout to start after status bar . But not sure how to do this.
Try this code...
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
getWindow().setStatusBarColor(Color.TRANSPARENT);
}
}

I've successfully set the app in the immersive mode because I want to hide the status bar (on the top screen) and the navigation bar (on the bottom screen).
The problem is that when the activity changes the bottom bar automatically arise and immediately after go down and disappear.
I want to avoid this.
All activities have the style AppTheme.NoActionBar set in the manifest:
android:theme="#style/AppTheme.NoActionBar"
And in the OnCreate all have the following code:
getWindow().getDecorView().getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
GlobalFunctions.setFullscreen(getWindow().getDecorView());
}
});
Where this is the setFullscreen() function:
public static void setFullscreen(View decorView){
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;
decorView.setSystemUiVisibility(ui_Options);
}
Should I set these attributes before the onCreate in the activity lifecycle? or there are other solutions? or I've implemented the immersive mode in the wrong way?
You don't need to set the global layout listener. Just invoke the setFullscreen function before super.onCreate()
Use this code in manifest activity tag
android:theme="#style/AppFullScreenTheme"
create this style in style.xml
<style name="AppFullScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:fontFamily">#font/montserrat</item>
<item name="android:windowContentOverlay">#null</item>
</style>
else use this in your activity class
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
this worked for me.
I want to set a transparent status bar, not a navigation bar.
what I tried
window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
But it set Status bar and navigation bar both transparent. I want only Status bar transparent
I also want to set different status bar color based on Fragment, And my navigation drawer is an overriding status bar, like this
Set these properties in your theme:
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
And in your layout you want to have a transparent status bar, set below attribute:
android:fitsSystemWindows="true"
On Lolipop and above:
window.statusBarColor = ContextCompat.getColor(this, android.R.color.transparent)
And on Marshmallow and above for transparent status with dark icons
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
or transparent status with light icons
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
Wait, it is not a duplicate
A similar question has been asked here, but not addressing dark-text status bar.
What I want to do
I want to achieve 3 things at the same time:
Transparent status bar (Not hiding it!)
Dark-text status bar
Opaque (or black) navigation bar (which does not let activity content inflate underneath it)
What I have tried
The solution
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
can only achieve 1 and 3;
The solution here can only achieve 1 and 2;
And the solution here can only achieve 2 and 3....
The Question
So is there a way to achieve all 1, 2 an 3?!
Inside styles.xml:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="android:navigationBarColor">#android:color/black</item>
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
In activity's onCreate():
override fun onCreate(savedInstanceState: Bundle?) {
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
Will result in this:
An app that uses immersive mode leaves a black bar at the bottom of the screen when the app is returned to after waiting a while (activity is destroyed).
What is happening: (I have enabled the developer option: "Don't keep activities" to reproduce this).
First time launch of the app. Immersive mode works as expected.
Swipe up to reveal the 'immersive sticky' nav bar, and use the 'Home' button to leave the app. The background of the nav bar briefly shows a black background before the app closes.
Use the 'Recents' button, and select the app to resume it.
The app opens to briefly reveal the nav bar over a black bar. The system ui collapses into immersive mode but the black bar remains.
This bug also only appears on Lollipop, not KitKat.
I have stripped back the app to simply launching a dummy activity with no functionality apart from setting System UI flags:
public class DummyActivity extends FragmentActivity {
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
setSystemUiVisibility();
}
}
public void setSystemUiVisibility() {
if (getWindow() != null && getWindow().getDecorView() != null) {
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);
}
}
}
EDIT:
After creating a new fresh project with only this Activity I have seen this issue reproduced when using an app theme extending "android:Theme.Holo"..., and fixed the issue in this sample project when I extend the Material theme instead:
Change
<style name="AppTheme" parent="android:Theme.Holo.Light.NoActionBar.Fullscreen">
</style>
to
<style name="AppTheme"parent="android:Theme.Material.Light.NoActionBar.Fullscreen">
</style>
Unfortunately this fix hasn't solved the issues in my main project, but it brings me closer to a solution and might help others with the same issue.
I was having the same problem. Here are a few updates I made which made it go away. Hopefully one of these works for you!
activity_main.xml
android:fitsSystemWindows="false"
style-v21
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowSharedElementsUseOverlay">false</item>
MainActivity.java
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
| View.SYSTEM_UI_FLAG_FULLSCREEN
);
For me it was a black bar at the top. Key thing was this in the activity style:
// Important to draw behind cutouts
<item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>
Here is my code:
1- In Activity
private fun hideSystemUI() {
sysUIHidden = true
// 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
window.decorView.systemUiVisibility = (
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
// Hide the nav bar and status bar
or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // Hide nav bar
or View.SYSTEM_UI_FLAG_FULLSCREEN // Hide status bar
)
}
private fun showSystemUI() {
sysUIHidden = false
window.decorView.systemUiVisibility = (
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
// Set the content to appear under the system bars so that the
// content doesn't resize when the system bars hide and show.
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION // layout Behind nav bar
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN // layout Behind status bar
)
}
2- In root view of xml layout
android:fitsSystemWindows="false"
3- Style for the Full screen Activity:
<style name="FullscreenTheme" parent="AppTheme">
<item name="android:actionBarStyle">#style/FullscreenActionBarStyle</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowBackground">#null</item>
<item name="metaButtonBarStyle">?android:attr/buttonBarStyle</item>
<item name="metaButtonBarButtonStyle">?android:attr/buttonBarButtonStyle</item>
<item name="android:statusBarColor">#50000000</item>
<item name="android:navigationBarColor">#50000000</item>
// Important to draw behind cutouts
<item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>
</style>
<style name="FullscreenActionBarStyle" parent="Widget.AppCompat.ActionBar">
<item name="android:background">#color/sysTransparent</item>
</style>
Using
<style name="AppTheme"parent="android:Theme.Material.Light.NoActionBar.Fullscreen"> </style>
does solved the problem, but it only work for api:21.
In order to make it works for all system. You can create a directory called style-v21 in res directory, and put that style.xml there. Android system is smart enough to pick which one to use for new or old phone.
Anyone know how to disable/hide notification bar at the top which show battery and other things in android.
Any help will be appreciated.
EDIT: Please also add how can I hide ActionBar+NotificationBar for later android versions.
You could use a theme in your AndroidManifest.xml:
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
or change parent of your AppTheme to #android:style/Theme.NoTitleBar.Fullscreen like this
<style name="AppTheme" parent="Theme.NoTitleBar.Fullscreen">
</style>
then apply this theme on activities which you want Fullscreen like
android:theme="#style/AppTheme"
or use the following code snippet:
public class FullScreen
extends android.app.Activity
{
#Override
public void onCreate(android.os.Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
The answers above hide ActionBar too.
If you intend to only hide notification bar, use this code:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
be careful to put it before setContentView().
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
Another Simple option is to add <item name="android:windowFullscreen">true</item> on the theme you will apply to activities that don't need a notification bar...
like so..
<style name="AppTheme.Splash">
<item name="android:windowFullscreen">true</item>
<item name="android:windowBackground">#drawable/background_splash</item>
</style>
Works like charm
Successfully implemented a slightly modified version of #Martin's suggestion along with a custom theme to get rid of BOTH the Status and Navigation Bar.
public class MyActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//* Hides Notification Bar
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_my);
}
Top part is used to get rid of the Status bar. Add the following code to your #styles as a resource to kill off the NavBar as well.
<resources> <style name="NoNav" parent="#android:style/Theme.Holo.Light">
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style> </resources>
After you add this to your resource file, pop open AndroidManifest.xml and chance your application theme to "#style/NoNav".
Android UI bloatware eliminated :)
You can use this for 4.1 or upper versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
you can do like this in onCreate() method :
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
ActionBar actionBar = getActionBar();
actionBar.hide();
This answer is for android developers who like minimalist and simplified one-liner code. If you intend to only hide notification bar, use this code:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
be careful to put it before setContentView() in your on create() function of required activity.class
