I want to make a completely transparent status bar and content behind it.
My device runs with 24 API.
I use this code (in my AppCompatActivity):
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
setContentView(R.layout.activity_main);
}
but it doesn't make any effect, my content is still UNDER the status bar;
I also tried to put android:fitsSystemWindows="true" in my root view, but it didn't help either.
I also tried to put the code after setContentView, still no effect.
What am I doing wrong?
replace this with your code :
if (Build.VERSION.SDK_INT < 19)
{
View v = this.getWindow().getDecorView();
v.setSystemUiVisibility(View.GONE);
} else if (Build.VERSION.SDK_INT >= 19) {
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
| View.SYSTEM_UI_FLAG_FULSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
}
Use this function callFullScreen
public void callFullScreen(Activity activity)
{
activity.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);
}
You can remove some lines to get required result, and finally call callFullScreen(); inside onCreate

Fullscreen Activity in Android?
(40 answers)
Closed 5 years ago.
I have an App and SDK, both are different. I included my SDK into my App. Now the problem is I have issues with making my activity in fullscreen. In SDK, classes are NON-Activity class there is no GUI, only backend Process. so I want to make them Full screen view. Here I can not use:
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Because my activity Non-activity class so there is no more window.so plan to use this code,
ws.setJavaScriptEnabled(true);
htmlAd.addJavascriptInterface(new Object()
{
#JavascriptInterface
public void performClick(String strl)
{
Activity activity = (Activity) adViewContext;
if(strl.equals("base")){
View mDecorView = activity.getWindow().getDecorView();
Toast.makeText (activity, "ONE" + strl, Toast.LENGTH_SHORT).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);
}else{
View mDecorView = activity.getWindow().getDecorView();
Toast.makeText (activity, "TWO" + strl, Toast.LENGTH_SHORT).show();
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
}
}, "ok");
But it does not work, please guide me .
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
adjustFullScreen(newConfig);
}
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
adjustFullScreen(getResources().getConfiguration());
}
}
private void adjustFullScreen(Configuration config) {
final View decorView = getWindow().getDecorView();
if (config.orientation == Configuration.ORIENTATION_LANDSCAPE) {
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);
} else {
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
}
}
change your application level theme to
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"/>
i am having non rooted device. i want to disable BottomNavigationView buttons.i used below codes but none are working.
public void disablebottombars() {
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_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
public void FullScreencall() {
if (Build.VERSION.SDK_INT < 19) {
View v = this.getWindow().getDecorView();
v.setSystemUiVisibility(View.GONE);
} else {
//for higher api versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);
}
}
You can look at setting up a Single-purpose device. To do this, your app needs to be set as a device owner, which can be done by invoking adb shell dpm set-device-owner. You can have a look at Google's DPC sample app for full details.
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"
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>
