I am trying to expand a VideoView to full screen and horizontal mode whenever a 'full-screen' button is clicked, but I cannot find a way to expand the view completely over the whole screen. I have a toolbar and a tabbed layout I can't find a way to bypass both of them and apply the view over them. Anybody has ideas how I can achieve this?
Without code I am not sure of your layout but, translate your TabLayout out of the way and go to 'immersive' mode to hide all system bars. You can use the following method:
private void hideSystemUI() {
// Set the content to appear under the system bars so that the content
// doesn't resize when the system bars hide and show.
getWindow().getDecorView().setFitsSystemWindows(false);
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);
}
To come out of immersive mode, just use the following method:
private void showSystemUI() {
getWindow().getDecorView().setFitsSystemWindows(true);
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

I want to enable and to disable statusbar and navigation bar in my android app. For this i use next methods:
private void hideSystemUi() {
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);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
private void showSystemUi() {
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
where
decorView = getWindow().getDecorView();
It works okay: these methods show and hide statusbar with navigationbar, BUT there is the problem: when statusbar is hide, i can to show it with top-bottom swipe in top part of my screen; similar situation with navigationbar. So , how to resolve this? I want to disable these system view fully, without possibility to show them with swipe. Thanks.
I want to hide navigation bar. Onyl show it if the user drugs his finger from outside to inside.
I test this code:
#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);
}
}
The activity starts well and the navigation bars not appear. Buti have the next problems:
1) If a touch the screen anywhere the navigation bar is show.
2) When it's show, its not showing transparent.
3) Navigation bar never hides.
How can add this three items? What I'm missing.
Add the sticky flag View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY to setSystemUiVisibility as described in the documentation https://developer.android.com/training/system-ui/immersive.html#sticky
That way after swiping from the screen edge, navigation bars will show for some seconds and then hide again.
I tried setting systemUIView(View.GONE) and use Immersive Full-Screen Mode. But users can always get the naviagtion bar back by touching the bottom of the screen. The apps i mentioned above are able to hide it without root or setting default launcher.
Okay, I found a solution finally and here is how it's done:
Use SYSTEM_UI_FLAG_IMMERSIVE_STICKY to hide the navigation bar as follow, you may put the code inside onResume of your activity
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);
Then, add a system error window using WindowManger and overlay it on top of everything
you can put this unescapable view anywhere you like, but if you want to do it while users locked the screen, add this flag:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED, WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
Et voilà
Well I've never achieved this but it seems that you will need to set some other flags to get this kind of view :
When you use the SYSTEM_UI_FLAG_IMMERSIVE flag, it hides the system bars based on what other UI flags you have set (SYSTEM_UI_FLAG_HIDE_NAVIGATION, SYSTEM_UI_FLAG_FULLSCREEN, or both). When the user swipes inward in a system bars region, the system bars reappear and remain visible.
Here is a snippet that you can use to set these flags :
// 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);
}

Hope this help.
I am working on custom screen lock app where we need to full screen view hiding the top and bottom bars completely. The app is for Android phones only and not tablets. I achieved this partially by using Immersive mode but the issue is the bottom bar & top appears for few seconds on touching bottom or top of the screen.
Below is the code in my activity to do this :
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;
getWindow().getDecorView().setSystemUiVisibility(flags);
I have tried various options but unable to hide the bars permanently. Please advise.
I want to use the "immersive mode" in my app.
I am following the documentation and working properly:
private View mDecorView;
...
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
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
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
mDecorView = getWindow().getDecorView();
}
This enables immersive full-screen mode.
My problem is that I want to use only FLAG_IMMERSIVE_STICKY, as the same result as the Trello app:
The bars are transparent and are always visible.
I searched for information and different combinations, but I get the result I want.
I appreciate any help.
Thank you!
Trello is using translucent bars [1], not immersive mode, with a custom transparent action bar background.
[1] https://developer.android.com/about/versions/android-4.4.html#TranslucentBars
The documentation also states that you have to set the UI Flags for the activity in the onCreate method.
- https://developer.android.com/training/system-ui/immersive.html
Implement these two methods and call hideSystemUI in the onCreate method
// 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);
}
This should hide the statusBar and the navigationBar.
The documentation states that this should hide both, navigation and statusbar.
For me it just hides the StatusBar.
I hope this helps.
The flags you're looking for are:
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS and
WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION
You can also use the flags in your theme using:
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
Unfortunately, it won't immediately appear like the Trello app if your app uses an action bar. You'll have to use some tricks/hacks to make it look like the Trello app. In the case that your app uses action bars, you could save yourself the time and use this library instead*. Needless to say, this will only work on API 19+.
*Personally, I don't endorse use of transparent system bars just for the sake of extending action bar colors. I feel it should only be used if you have content to show underneath the system bars or if you have a full-screen activity.
