Hi All

I want to add a ListView under the Main activity of CameraEx example at the level of the picture size Button and effect button.
The code works fine for the effect button. i get all the supported effects but for the image size button I get a java error (see log)

My code for the button is:

Sub btnPictureSize_Click
    Dim pictureSizes() As CameraSize = camEx.GetSupportedPicturesSizes
    Dim current As CameraSize = camEx.GetPictureSize
  
  
    LvPSize.Color = Colors.black
    LvPSize.SingleLineLayout.ItemHeight = 25dip
    LvPSize.SingleLineLayout.Label.TextSize = 15

    For i = 0 To pictureSizes.Length-1
  
    'Msgbox(pictureSizes(i).Width&"x"&pictureSizes(i).Height,"")
        LvPSize.AddSingleLine(pictureSizes(i).Width&"x"&pictureSizes(i).Height)
    Next
  
    Activity.AddView(LvPSize,0, btnPictureSize.Height, 40%x, 60%y)
    ....

The behavior is weird as the picture size listview (LvPSize) begins to display only 3 values and then the debugger stops....

The same code for the effect button works like a charm :

Sub btnEffect_Click
    Dim effects As List = camEx.GetSupportedColorEffects
    If effects.IsInitialized = False Then
        ToastMessageShow("Effects not supported.", False)
        Return
    End If
  
    LvEffect.Color = Colors.black
    LvEffect.SingleLineLayout.ItemHeight = 25dip
    LvEffect.SingleLineLayout.Label.TextSize = 15

    For i = 0 To effects.Size-1
        LvEffect.AddSingleLine(effects.Get(i))
    Next
  Activity.AddView(LvEffect,btnEffect.Left, btnEffect.Height, 40%x, 60%y)
  
End Sub


Sub LvEffect_ItemClick (Position As Int, Value As Object)
    camEx.ColorEffect=LvEffect.GetItem(Position)
    'ToastMessageShow(LvEffect.GetItem(Position), False)
    camEx.CommitParameters
    LvEffect.clear
    LvEffect.RemoveView
End Sub

Sub LvPSize_ItemClick (Position As Int, Value As Object)


    LvPSize.clear
    LvPSize.RemoveView
End Sub

I cannot figure out where is my mistake ? Is there an interaction between the cameraEx picturesize function and Listview ?
Thanks
Alain
