Android statusbar overlay with ActionBar

Question

I know that I can make the ActionBar overlay using requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY)
and can toggle/show the status bar in my screen (by switch

Answer 1

Put this method in onCreate() method activity:

getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

Answer 2

so apparently, you can do this in Jellybean. google includes two examples in the api docs. here is a link: http://developer.android.com/reference/android/view/View.html#setSystemUiVisibility%28int%29

summary: use setSystemUiVisibility on a view to toggle visibility (on jellybean+).

Answer 3

It's not perfect, but this is how I have achieved what you want:

In onCreate:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

Then:

private void hideStatusBar() {
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);

}

private void showStatusBar() {
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

}

I also have a style on the activity with the following:

 <style name="readingStyle" parent="@style/Theme.Sherlock">
     <item name="android:windowActionBarOverlay">true</item>  
     <item name="windowActionBarOverlay">true</item>       
 </style> 

Your activity will shift down when the status bar shows, but I don't think it's too noticeable.

Why you dont make it in the Manifest

android:theme="@android:style/Theme.Black.NoTitleBar"

than you have no statusbar and more space for the Actionbar??
