Android Question Horizontal ScrollView with image

[Matteo Granatiero]

I downloaded this project from this site but I can not replace the colors with images contained in a route of the phone

Here's example with images

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Main")
    hsvPages.Panel.Width = 4 * hsvPages.Width
    
    hsvTimer.Initialize("hsvTimer", 200)
    
    objPages.Target = hsvPages
    objPages.SetOnTouchListener("hsvPages_Touch")
    
    Dim bd As BitmapDrawable
    bd.Initialize(LoadBitmap(File.DirAssets,"icon.png"))
    
    Dim i As Int
    For i = 0 To 3   
        pnlPages(i).Initialize("")
        pnlPages(i).Background = bd
        hsvPages.Panel.AddView(pnlPages(i), i * hsvPages.Width, 0, 100%x, 100%y)
    Next
End Sub

what is objpages?

what is objpages?

It's from your example. Seems to be Reflector

it works but it loads 8 times only 1 image, in the path there are 8 images

  Activity.LoadLayout("Main")
    hsvPages.Panel.Width = 4 * hsvPages.Width
   
    hsvTimer.Initialize("hsvTimer", 200)
   
    objPages.Target = hsvPages
    objPages.SetOnTouchListener("hsvPages_Touch")
    root=File.DirRootExternal
    path1 = root & "/BetaVersion/"
    For Each f As String In File.ListFiles(path1)
    Dim bd As BitmapDrawable
    bd.Initialize(LoadBitmap(path1,f))
   
    Dim i As Int
    For i = 0 To 8
        pnlPages(i).Initialize("")
        pnlPages(i).Background = bd
        hsvPages.Panel.AddView(pnlPages(i), i * hsvPages.Width, 0, 100%x, 100%y)
    Next
    Next

    Next

Of course you have to create new bitmap for every background like this

Dim path1 As String = File.Combine(File.DirRootExternal,"/BetaVersion/")
Dim files As List = File.ListFiles(path1)
Dim bd As BitmapDrawable
  
For i = 0 To files.Size - 1
    Dim p As Panel : p.Initialize("")
    hsvPages.Panel.AddView(p, i * hsvPages.Width, 0, 100%x, 100%y)
    bd.Initialize(LoadBitmapSample(path1,files.Get(i),p.Width,p.Height))
    p.Background = bd
Next

also I'm not sure for which purpose this app is going to be, but target api 14 and what you are doing with this example pretty much denies you ever sharing this kind of app in PlayStore.

load only 4 images / 8 images.... why?

Why aren't you using xCustomListView? It supports horizontal scrolling.
