iOS Question Segmented Control and various layouts

[Rokiu86]

Hi.

Following this example:

https://www.b4x.com/android/forum/threads/multiple-pages-example.48170/#content

I understood the navigation between layouts.

My target is have a SegmentedControl on the top of a layout with 4 Items. And for each Item charge a layout. My question is, Do I need have a SegmentedControl on the 4 layouts? or Can I have a only SegmentedControl and work with panels?

For example:

SC as segmentedcontrol

Sub SC_IndexChanged (Index As Int)
   select index
      case 0:
panel1.visible=true
panel2.visible=false
panel3.visible=false
panel4.visible=false
      case 1:
panel1.visible=false
panel2.visible=true
panel3.visible=false
panel4.visible=false
      case 2:
.
.
.
      case 3:
.
.
.
end select

end Sub

In my opinion work with panel for this target is not the best option, because all the app have only a layout, but I dont know how can I do this with layouts.

Any Idea or example?

Thanks!!!!

Consider using TabHostController instead. This is the more natural solution.

With a segmented control you have two options:
1. Use multiple panels.
2. Use multiple pages with multiple segmented controls.

Always try to avoid duplicating code.

You can do something like:

Dim panels() As Panel = Array As Panel(panel1, panel2, panel3, panel4)
...

'then you can easily change panels:
'change to panel i (0 - 3):
For x = 0 to panels.Length - 1
 panels(i).visible = x = i
Next

'or more "standard":
If x = i Then panels(i).Visible = True else panels(i).Visible = False
