I'm sorry - I was out of town, without wifi...

That's not true Don. But, here's a piece of the code:

B4X:

Sub Globals
    Dim pnl2, pnlMain1 As Panel
    Dim Label1 As Label   
    Dim ImageView1 As ImageView
    Dim label2 As Label
    Dim StrUtil2 As StringUtils
End Sub

    pnl2.Initialize("")
    pnl2.color = Colors.Red
    ImageView1.Initialize("Back")
    ImageView1.Color = Colors.Red
    ImageView1.Bitmap = LoadBitmap(File.DirAssets,"back.png")
    Activity.AddView(pnl2,0,0,100%x,52dip)
    Activity.AddView(ImageView1,4dip,4dip,44dip,44dip)

Kind regards,

Kepler

Can you post the image? It could the the PNG file itself.
If that's the case, I'll be able to fix it in less than one minute.

The image file is fine. I've checked the transparency with Photoshop.

As already said !
Post a small project showing the problem, so we can see what exactly you have done and we can test it !

My god... I've posted the main problem - the project is too big!

BUT...Wonder had a point. Photoshop is assuming the image to have a transparent ground. Not true.
I transformed it into a bitmap in coreldraw and exported it as png. That worked...

I can seem to able to understand why photoshop doesn't do the same...I've been working with this program for ages.

Well...these are mysterious ways...

Kind regards,

Kepler

Sounds weird.
I always create my images with Photoshop, never had a problem with transparency.
But make sure your image in Photoshop has no background layer.

Here try this:

B4X:

'Hmm
    pnl2.Initialize("")
    pnl2.color = Colors.Red
    ImageView1.Initialize("Back")
    ImageView1.Color = Colors.red
    ImageView1.Bitmap = LoadBitmap(File.DirAssets,"back.png")
    Activity.AddView(pnl2, 0, 0, 100%x, 60dip)
    pnl2.AddView(ImageView1, 2dip, 2dip, -1, 56dip)

Add this line:

B4X:

ImageView1.Gravity = Gravity.FILL

The reason is the ImageView1 is set to 44dip but the original image is 56x56pixel.

B4X:

Activity.AddView(ImageView1,4dip,4dip,56dip,56dip)

Are you sure ?
Mostly, the problem is not where YOU think but somewhere else.
If you had posted a small project showing the problem you would have got a solution much faster, instead of needing the helpers try to guess what you could have done wrong!
