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);
The following is the official way of hiding the status bar:
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();
However, the status bar shows up on the first touch. Is it possible to prevent this. One can use getWindow().getDecorView().setOnSystemUiVisibilityChangeListener() to hide it again, but its brief display is a nuisance.
For API 19 and above, Immersive Full-Screen Mode is available for dealing with this.
I have a problem hiding navigation bar at the bottom of the screen in android.
Every solution I've tried doesn't work exactly as I want it to work, except one.
Modifying build.prop with new entry 'qemu.hw.mainkeys=1' worked ok, but it disables navigation bar for whole android system.
Is there possibility to disable navigation bar like this only for one app?
Try this:
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);
(Source)
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
decorView.setSystemUiVisibility(uiOptions);
Use this code in onCreate(), it will hide status bar and navigation bar until users swipe down from top of the screen
I hide the navigation bar (see below) but when I press the menu button on action bar the navigation bar immediately appear.
Can I hide nav. bar permanently?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
setContentView(R.layout.activity_fomenu);
}
Take a look at the documentation. It says to hide the navigation use
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);
You're already doing that. But then it says
With this approach, touching anywhere on the screen causes the navigation bar (and status bar) to reappear and remain visible. The user interaction causes the flags to be be cleared. Once the flags have been cleared, your app needs to reset them if you want to hide the bars again. See Responding to UI Visibility Changes for a discussion of how to listen for UI visibility changes so that your app can respond accordingly.
This means that you will have to reset the flags when the user selects the options menu. A sample code is also given here.
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);
