B4J Question B4XImageView in B4J

[Colin Evans]

Hi, can anyone please help, I'm trying to implement a playing card display, and one of the examples in B4A shows the display using B4XImageView but the syntax isn't the same in B4J

Example in B4J in the FlipCards example the following code seems okay

For X = 0 To Columns - 1
        For Y = 0 To Rows - 1
            B4XImgViewCard(Counter).Initialize(Me, "B4XImgViewCard")
            B4XImgViewCard(Counter).AddToParent(PnlMain, OffSetX + x * (CardSize + 10dip), OffSetY + y * (CardSize + 10dip), CardSize, CardSize)
            B4XImgViewCard(Counter).B4XBitmap = CardBack 'Set card back image
            B4XImgViewCard(Counter).Tag = $"${LstCards.Get(Counter)}~${Counter}"$ 'Store card name and card position

            MapRotation.Put(Counter, 0) 'Store card name and set rotation to 0 
            Counter = Counter + 1
        Next

But in B4J there is no option to .AddToParent or .B4XBitmap any idea's or work arounds would be greatly received, many thanks

Neither B4XImageView nor ImageView have AddToParent method.

Hi, thanks for the reply, I just thought B4X..... were the same in all languages, so if it was available in B4A it would have been in B4J, oh well maybe it's something for the future

Thanks for your suggestion I'll have a go, thanks again

Maybe I didn't explain well.
Not even in B4A does B4XImageView have the AddToParent method. I don't know what type that array of your code is.

B4XImageView API is identical in all platforms.

You should add it with the designer or with XUIViewsUtils:

Dim iv As B4XImageView = XUIViewsUtils.CreateB4XImageView
pnl.AddView(iv.mBase, ...

Thanks to both of you, I think I am / was confused with the example I downloaded from the forum, in post 9 of the following link

Card flip (flip between 2 images)

Hi I am looking to flip card (many cards), meaning flip between 2 images with the card flip effect. I found this, but this is very limited library https://www.b4x.com/android/forum/threads/flipimageview.37396/#post-274973 is there other solution? library?

And on post 26 on the link, LucaMs, confused me more as he seemingly amended the code, which I can't run got errorss
