Setting background image...

[Gary Miyakawa]

I'm trying to change the back ground image on both a ProgressBar and SeekBar view.

I've used the following code and the imageview1 does show the correct image, the others are not changed from their standard grey background.
What am I doing wrong ?

   Activity.LoadLayout("1")
   Dim bmp As Bitmap
    bmp.Initialize(File.DirAssets, "abc.png")
    SeekBar2.SetBackgroundImage(bmp)
   seekbar4.SetBackgroundImage(bmp)
   imageview1.SetBackgroundImage(bmp)
   pbBar1.SetBackgroundImage(bmp)

Thanks,

Gary M

ProgressBar and SeekBar do not support an additional background image.

Ok, that would explain it! Guess the documentation needs to be adjusted for that.

Thanks !

Ok, that would explain it! Guess the documentation needs to be adjusted for that.

In the B4A Documentation Wiki, functions/properties common to all (or most) views are shown on one page; those unique to one (or a few) views are shown on the view's page. The Bitmap property does not appear on the common views page; it is on the ImageView page but not on the ProgressBar and SeekBar pages.

OTOH, the Common Views page does show:

Background As android.graphics.drawable.Drawable
Gets or set the background drawable.

and frankly, it's not clear to me exactly what that means. (I just copied it from the HelpViewer and futher searching didn't turn up a clear definition.)

The documentation at
Basic4android - Views (Core)

Clearly shows "setbackgroundimage" as an option and it does also show up in the IDE...

Just needs to be updated for future folks...

You're right. I've changed this in the Wiki. Thanks.
