Material title bar repro
Tested on 184.108.40.20603-pre2 with an S6 using API Level 23
Used the following to try to go fullscreen:
<style name="MyTheme" parent="MyTheme.Base">
<style name="MyTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
Title bar doesn't go away. The text on it is successfully hidden, but the frame stays intact.
Please see repro
are you using FormsAppCompatActivity?
Yes. Please see MainActivity.cs
I'm having a related issue. See here https://bugzilla.xamarin.com/show_bug.cgi?id=38227
Seems like there is no way to enter full screen mode at startup at the moment. :|
I have this issue too - occurs only if using Master Detail Page on Android. The Code I am using is:
View decorView = Window.DecorView;
var uiOptions = (int)decorView.SystemUiVisibility;
var newUiOptions = (int)uiOptions;
newUiOptions |= (int)SystemUiFlags.LowProfile;
newUiOptions |= (int)SystemUiFlags.Fullscreen;
newUiOptions |= (int)SystemUiFlags.HideNavigation;
newUiOptions |= (int)SystemUiFlags.Immersive;
decorView.SystemUiVisibility = (StatusBarVisibility)newUiOptions;
The result is that the status bar is cleared but not hidden and a blue empty bar stays visible.
Amendment: The example above worked before I switched to Material Design.
I also have this problem. The title bar occupies space even though it's not supposed to be there when hidden.
Any update on this? I can't update to AppCompat unless this is fixed.
In AppCompat, Forms.SetTitleBarVisibility (AndroidTitleBarVisibility.Never); does not work.
Please fix it as soon as possible. This issue is preventing us from switching to FormsAppCompatActivity.
Please see: https://github.com/xamarin/Xamarin.Forms/pull/350
Should be fixed in 2.3.4-pre1. Thank you!
I have checked this issue with Xamarin.Forms 2.3.4-pre1 and this issue has been fixed.
Hence closing this issue.
I think this bug has returned in Xamarin.Forms 220.127.116.11-pre3, tested on a S4 API 21 and Nexus 5 API 25.
In the same scenario i set the flag :
But the underlay(frame) is still shown, the text is successfully hidden.
The underlay was removed by this PR: https://github.com/xamarin/Xamarin.Forms/pull/892
I'm not sure if it was included in -pre3.
This fix hasn't been included in any pre/release >= 2.3.5 of Xamarin.Forms...
not possible to hide statusbar
<style name="MainTheme" parent="MainTheme.NoActionBar">
// protected override void OnCreate(Bundle bundle)
//Window.DecorView.SystemUiVisibility = StatusBarVisibility.Hidden;
Samsung Google Galaxy Nexus (android 4,3 Api 18)
Any updates on that bug? I experience the same issue - the text from status bar is disappeared but frame is still there:
