Keith Yong said:

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?

Page2.Initialize("")

nav1.NavigationBarVisible=false

nav2.showpage(page2)

nav1.Showpage(page1)

End Sub

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

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))

Please create a small project with the layout and upload it.

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

See the attached example.

It sets the navigation bar background color to avoid the black bar and it uses CallSubPlus to hide the bar 200ms after the page appears.
