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>

I am new to Android Development. I want my app to support the screen size of my device i.e. 1080 x 2160 pixels. Currently there is a black bottom bar that is displayed in place of where the navigation buttons would have been.
Please note that I do not want Full Screen Mode. I have disabled the button navigation on my device. It is only for this app that that the bottom black rectangle is showing.
I just want my app to support the gesture navigation system of my device instead of buttons.How do I make the bottom bar go away using Java (Android Studio) so that my app utilizes that space?
question is old but I faced the same issue and didnot find the solution on SO.
this problem occurs for long screens
We recommend that you design your app to support aspect ratios of 2.1 or higher. For this, you would add the following to the "application" element in your Manifest file:
<meta-data android:name="android.max_aspect" android:value="2.1" />
from here
I had the same issue, updated manifest file with this or remove if you have one.
before
<meta-data
android:name="android.max_aspect"
android:value="2.1" />
after
<meta-data
android:name="android.max_aspect"
android:value="2.4" />
working for me now.
Hi please Try below code
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
You can try this
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (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);
}
}
Try to add this code
#Override
protected void onCreate(Bundle savedInstanceState) {
...
hideSystemUI(this, 1000);
}
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
// Hide bar after 1 second
hideSystemUI(this, 1000);
}
}
public static void hideSystemUI(#NonNull final Activity activity, final int delayMs) {
View decorView = activity.getWindow().getDecorView();
int uiState = View.SYSTEM_UI_FLAG_IMMERSIVE
| 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;
final Handler handler = new Handler();
decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
#Override
public void onSystemUiVisibilityChange(int visibility) {
if (visibility == View.VISIBLE) {
Runnable runnable = new Runnable() {
#Override
public void run() {
hideSystemUI(activity, 1000);
}
};
handler.postDelayed(runnable, delayMs);
}
}
});
decorView.setSystemUiVisibility(uiState);
}
WARNING
If you have two activities, add this before changing
View decorView = getWindow().getDecorView();
decorView.setOnSystemUiVisibilityChangeListener(null);
Some android phones have soft buttons (back, home, menu). I manage to hide them using setSystemUiVisibility as described here.
However, how to make the softbuttons visible pragmatically?
You can use setSystemUiVisibility()
Request that the visibility of the status bar or other screen/window decorations be changed.
SAMPLE CODE
public class MainActivity extends AppCompatActivity {
TextView tvTextView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
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);
setContentView(R.layout.activity_main);
tvTextView=findViewById(R.id.tvTextView);
tvTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
getWindow().getDecorView().setSystemUiVisibility(View.VISIBLE);
}
});
}
Setting View.SYSTEM_UI_FLAG_VISIBLE worked for me.
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
This question already has answers here:
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 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
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"
