First of all, thanks for helping to answer my previous question and manage to resolve it.

Here is some example, page 1 is the login screen without the navigation bar, and page 2 is forgot password with showing the navigation bar and the back button.

Question 1: how do I preset the page 1 layout hide the navigation bar and page 2 show the navigation bar?

Question 2: how to I change the back button (Page 2) to white color?

1. Try to create 2 navigationController

Example

B4X:
Dim Nav1, Nav2 as NavigationController
Dim Page1,Page2 as Page

Sub CreatePages

Nav1.Initialize("")
Nav2.Initialize("")
Page1.Initialize("")
Page2.Initialize("")

nav1.NavigationBarVisible=false

nav2.showpage(page2)

nav1.Showpage(page1)

End Sub

Sub ChangePage

nav1.showpage(nav2)

end sub

2.

B4X:
Dim no as NativeObject=NavControl
no.getfield("navigationBar").setfield("tintColor",no.ColorToUIColor(youColor))

it seems like nothing show even I added the line to call CreatePages under Application_Start routine.

B4X:
Private Sub Application_Start (Nav As NavigationController)

CreatePages

End Sub

You can use the Page_Appear event to hide or show the bar:
B4X:
Sub Page1_Appear
   NavControl.SetNavigationBarVisibleAnimated(False)
End Sub

Sub Page2_Appear
   NavControl.SetNavigationBarVisibleAnimated(True)
End Sub


Thanks Erel, however it looks like a bit weird when I call back the Page1 and hide the navigationbar, so I decided the Hide the NavigationBar and create a custom Panel on Page 2 with the Back button. But the challenge is how to set the gesture swipe from left back to Page 1?
