How do I make the navigation bar transparent in landscape?
It works in portrait.
My device version is Kitkat(Nexus5)
The Youtube Kids works in KitKat.
I solved this problem.
We cannot set a color to navigation bar in landscape under lollipop.
But we can set transpalent temporarily these version.
You set the flag which is View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY.
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);

mContext.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
I am using the above codes to hide enter the full screen mode. It can be exited by swiping back, top or bottom. However, the Action Bar remains hidden, while the status bar and navigation bar appears (Picture 2).
How can I bring up the ActionBar ? Or detecting the "Exit" (Picture 3) event listener so that I can call the following to show ActionBar?
mContext.getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
);
Due to design requirement, I can't use the touch listener to bring up the ActionBar() in this case.
I have an application which will show fullscreen without problem on Android 4-6. But once test on Android 7.0, although the navigation and status bar are hide, the navigation bar position seems still occupied by a white bar. My application cannot automatically resize to occupy that space.
mContentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
| View.SYSTEM_UI_FLAG_FULLSCREEN
| 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);
I use the above code to do the fullscreen. Please advise. Thanks.
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 am unable to show the action bar when SYSTEM_UI_FLAG_LAYOUT_STABLE is used as following:
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
I use getSupportActionBar().show() and getSupportActionBar().hide() to show or hide the action bar. If SYSTEM_UI_FLAG_LAYOUT_STABLE is taken out from the above code, everything will be fine - the action bar can be shown or hid without any problem.
Could anyone shed some light on this?
I'm trying to use the immersive mode introduced in Android 4.4. I use this code to set the visibility and it works exactly how I want it to:
View decorView = getWindow().getDecorView();
int uiOptions = //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;
decorView.setSystemUiVisibility(uiOptions);
However, it puts a line on the display. I have a screenshot but cannot post it because this is my first question. I have no idea what it is or how to get rid of it. Can anyone help?
