I have an icon on top of Seekbar
The icon must be moving on changing seekbar value
I try to use the below code
pnlmarker.Left = Value.As(Int) * pnlmarker.Width

But not working

I used pnlmarker.Left = Value.As(Int) * 2.34 and I approached result but that is not accurate

Use the source of the nice B4XSeekBar custom view (XUI Views), rename the class and add this drawing to the custom view.
