I want to hide Bottom Option Bar in Android. I don't know whether we call it Option Bar it or not.
Please check it out Image below : Tell me if we call it something else. It is in bottom.
Now, I want to hide it. How to do it ?
It's called navigation bar, the reason for it only having the options button is probably because your device has hardware buttons for home and back, that's why it looks like an options button only bar.
Refer to the docs for hiding it, although it will only work for versions supporting it.
For 4.0+
View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

Hello.
I want to adjust the size of devices resolution and splash image in the splash screen.
I did try to apply png file to 9patch.
But I made gap between device to navigation bar.
And I'd try, try, try, I have reached this point.
I don't know how control navigation bar and button.
Please please please, teach me how hide navigation bar in the splash screen or how change the color in navigation bar's buttons.
Kindly review and give feedback.
It would be better to have some code so we can suggest what could be improved.
But here is some suggestions from android developer documentation.
View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

I thought that is a solution for that but I cannot find it. I know that I can disable back button by overriding onBackPress() method and not call super.onBackPress() but it only disable, I want to remove/hide from navigation bar this button.
And I known that on some device where the back button is a part of hardware it can be done.
To be clear I mean arrow on below screen:
You can find solution in the documentation.
View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
and this code should be placed in onCreate() method in the Activity after initializing all UI elements.
use this code in your onCreate() method : to hide
View bView = getWindow().getDecorView();
bView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
I have an Android 5.1 tablet with root. I'm implementing an app in kiosk mode. For that I'm using the immersive mode, which nicely hides the navigation and status bar. But with a swipe these bars reappears, which is not what I want.
With adding qemu.hw.mainkeys=0 to the end of the build.prop file I was able to get rid of the navigation (bottom) bar. Unfortunately, the status bar still re-appears when i pull down from the upper side of the screen.
Is there a possibility to get rid of the status bar by editing the builds.prop file or in another way?
Not so familiar with root device, so i think about different way, have you try to hide it in main activity?
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();
This applied for 4.1 and Higher, see more in Android Developer
My problem is simple and I have been unable to find a solution. The menu bar is very annoying in my app and I am hoping that there is a way to remove it.
Looking at Hiding the Navigation Bar I found this:
You can hide the navigation bar on Android 4.0 and higher using the SYSTEM_UI_FLAG_HIDE_NAVIGATION flag. This snippet hides both the navigation bar and the status bar:
View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
I do not know if that's exactly what you was looking for, but you can test it.
I suggest you read more about native modules, it enables you to write native code and access it from JS.
http://facebook.github.io/react-native/docs/native-modules-android.html#content
Also the StatusBar module is very similar to what you want to do here, you can have a look at the source.

I am trying to make an activity that is completely fullscreen in landscape, and have the status bar and navigation buttons visible in portrait.
I have to be able to do this programatically.
This is how I tried make the app go fullscreen.
private void hideNavigationAndStatusBars(){
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); // these work only on API 21 and above
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
The problems are the following :
On some devices, I get a blank portion on the top of the screen, that is equal to the height of the status bar, even though the status bar is not showing
On other devices, the activity fills the whole screen, but when I click anything, the status bar and navigation bar appear, they resize the layout and it looks very ugly
What I am trying to achieve:
The activity should fill the whole screen in landscape, positioned behind the status bar and navigation bar, if they appear
When the user clicks on the screen, he/she should interact with the screen. Instead the first click displays the status and navigation bars and the interaction is possible only after this
The status bar should only appear when the user drags from the top
to hide action bar call getActionBar().hide() method.
And to make activity full screen call
this method
requestFeature(Window.FeatureNo_Title)
Use immersive mode and system ui stable flag to achieve this. For more information please refer the document in developer site.
