iOS Question StatusBar Background transparent

F.Campanella · Dec 3, 2015

Hi,
I've need to make Statusbar in transparent background.
I follow your instructions for various threads but the results is not good.

I've used this code:

B4X:

NavControl = Nav

   Dim no As NativeObject = App
   no.RunMethod("setStatusBarStyle:", Array(1))

   Dim no As NativeObject = NavControl
   no.GetField("navigationBar").RunMethod("setBarStyle:", Array(1))

   Page1.RootPanel.Color = Colors.Transparent

the results is displayed in the image. The status bar remain opaque with black color

Can you help me?

Try to hide the statusbar, load your views and after that show the statusbar again.

I don't believe you can change the color of the status bar. You can change the style only. In iOS 7 the status bar is by default transparent.

When an app is launched panel appears splash, I hide the statusbar ... when the app finishes loading all the information, I hide the splash panel and make visible the statusbar again (thanks Narek)

Hello Campanella, do you have a little example with a page, a image (to background) and statusbar transparent?

Thanks

Hi Alberto, this is very simple...

Put this code in the Project attributes region

B4X:

#PlistExtra: <key>UIViewControllerBasedStatusBarAppearance</key><false/>

At begin of the Application_Start put the following code:

B4X:

...
...
...
Private Sub Application_Start (Nav As NavigationController)

NavControl = Nav
   NavControl.NavigationBarVisible = False

Dim no As NativeObject = App
     no.RunMethod("setStatusBarStyle:", Array(1))
 
   Dim no As NativeObject = NavControl
     no.GetField("navigationBar").RunMethod("setBarStyle:", Array(1))
 
   Dim no As NativeObject = App
   no.RunMethod("setStatusBarHidden:animated:", Array(True, False))

Is All,

tell me if you are solved!

F.Campanella · Mar 10, 2016

This is the code that I used for show my work-example that I posted here:

B4X:

Private Sub Application_Start (Nav As NavigationController)

#region Prime Inizializzazioni

   GPS.Initialize("GPS")

   LoadConf

   CaricaCitta

   NavControl = Nav
  
   Dim no As NativeObject = App
     no.RunMethod("setStatusBarStyle:", Array(1))
  
   Dim no As NativeObject = NavControl
     no.GetField("navigationBar").RunMethod("setBarStyle:", Array(1))
  
   Dim no As NativeObject = App
   no.RunMethod("setStatusBarHidden:animated:", Array(True, False))
  
   Page1.Initialize("Page1")
   Page1.RootPanel.Color = Colors.Transparent
   PageActOrarie.Initialize("PageActOrarie")
   PageActOrarie.RootPanel.Color = Colors.RGB(0,51,102) ' POI FAREMO IL COLORE GRADIENTATO UGUALE A QUELLO DELLA VERSIONE ANDROID
   PageActAltro.Initialize("PageActAltro")
   PageActAltro.RootPanel.Color = Colors.RGB(0,51,102)
   PageActConf.Initialize("PageActConf")
   PageActConf.RootPanel.Color = Colors.RGB(0,51,102)
   ClassActOrarie.Initialize(Nav)
   ClassActAltro.Initialize(Nav)
   ClassActConf.Initialize(Nav)
  
   BManager.Initialize
  
#end region

#region Immagine di Sfondo
  
   igvSfondo.Initialize("IV")
   igvSfondo.Bitmap = LoadBitmap(File.DirAssets, "sf_sereno1.jpg")
   igvSfondo.ContentMode = igvSfondo.MODE_TOPLEFT    
   Page1.RootPanel.AddView(igvSfondo, 0,0,100%x, 100%y)

#end region

...
...
...
...

This code worked for me...

P.S. The background image igvSfondo is the first View that I load in the RootPanel for the page.

Campanella,

Alberto Iglesias · Mar 11, 2016

Hello Campanella,

You try this sample I send? It´s based on your code, but is not with the same effect on StatusBar, can you check if I missing something?

Thank You.

Could you post a screenshot of your page ?

try this

B4X:

pagPrincipal.RootPanel.AddView(imgFundo, -20,0,100%x, 100%y)

Alberto Iglesias · Mar 11, 2016

perfectyl! Works!

But you put -20 in left! the correct line should be:

B4X:

pagPrincipal.RootPanel.AddView(imgFundo, 0,-20,100%x, 100%y)

Thanks!!!
