Android Question scrollview sample (or alternate idea)

[Zeev Goldstein]

hi

i need to create a view that will allow longer view that actual screen (too many items)
searching the forum brought up scrollview
i tried to find a sample as i couldn't find my way with it
is there a simple sample for a scrollview with a few buttons on it so i can use it for my needs?
thanks

You already got told to use xcustomListview.
Why ignoring all the suggestions?

Use xCustomListview

is there a simple sample for a scrollview with a few buttons on it so i can use it for my needs?

Start with the Example provided

[B4X] [XUI] xCustomListView - cross platform CustomListView

Update: As several other libraries depend on xCustomListView library, it is no longer recommended to use the code module. Use the library instead. There are several extension classes that add more features to xCLV. They are listed at the end of this post. Video tutorial: xCustomListView is...

You can define the scrollview (SCV) by the designer, in my case I made it on top third of the screen, then set the internal panel size and added by code a imageview (Iv1) . You can add more views to the internal panel.

    IV1.Initialize("")
    SCV.Panel.Width = 100%x
    SCV.Panel.Height = 100%y
    SCV.Panel.AddView(IV1, 0, 0, 100%x,  100%y)

If needed, use the event:

Private Sub SCV_ScrollChanged(Position As Int)
    Log(Position)
End Sub

thanks

my plan is not to add a table or list like the ample i was referred to above

what want to do is have a layout that is longer that actual screen height so i can add textedits and buttons
if possible to take existing layout and add to it the ability to scroll as i need to add more elements

this i can't find

so from your sample code i see you load LV1 - can load to it my panel or layout and by that have the scroll ability?
my app is B4A

 

[derez]

Yes !, and you can define all your added views in the designer as a layout file and set the internal panel with it.

thank you
i will try it and cross fingers...

i'm sure i missed something
or just got it wrong

here's my code - i get errors on the SCV part
without it it loads but of course not as needed

can you help?

thanks

 

[derez]

"here's my code -" - where ?

 

[mangojack]

Where?

can you help?

Yes.. If you post some code

 

[Zeev Goldstein]

Where?



Yes.. If you post some code

oops...

Sub Activity_Create(FirstTime As Boolean)

    'Activity.LoadLayout("Layout")

    Pnl.Initialize("")
    Pnl.LoadLayout("Layout")
    Activity.AddView(Pnl,0,0,100%x,100%y)

    
    ''IV1.Initialize("")
    SCV.Initialize(0)
    SCV.Panel.Width = 100%x
    SCV.Panel.Height = 100%y
    SCV.Panel.AddView(Pnl, 0, 0, 100%x,  100%y)
    
End Sub

Please use Xcustomlistview. Its easier than you can imagine

i did look at it as suggested above but from the sample i couldn't get to what i wanted
i don't need a scrolling list as in the sample, i need a form with buttons and textedits
the best will be the ability to take my existing views and load them into that "magical" customlistview
please mind that my app is classic b4a and quite old one

what you are doing is wrong
you create a panel with height 100%y and add it to the activity then you create the sv inner panel height also to 100%. so how should the height be larger then 100%y if you set both to 100%y???

this is how you should do it

Sub Globals
    Dim sv As ScrollView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    sv.Initialize(1000dip) 'height of the panel in Layout
    Activity.AddView(sv,0,0,100%x,100%y)
    sv.Panel.LoadLayout("Layout")
End Sub
