Android Question Combining a Listview into a Panel...

[Cableguy]

Hi Guys,

Trying to solve the SetLayoutAnimated behaviour issue, as shown here, I thought about combining a "snapshot" of the listview, into a panel background using canvas...

So I would have a combined image of the both views, thus the resizing would, hopefully be smother...
But for the life of me, I just can't figure out how to combine them!

here's my code:

Dim Bmp As Bitmap
    Dim bkg1 As Canvas
    Dim bkg2 As Canvas
    Dim DestRect As Rect
 
    bkg1.Initialize(Panel2)
    bkg2.Initialize(ListView1)
    DestRect.Initialize(0, 0, Panel2.Width, Panel2.Height) 'both views have the exact same size
    bkg1.DrawBitmap(bkg2.Bitmap, DestRect,DestRect)

    Panel2.SetBackgroundImage(bkg1.Bitmap)
    Panel2.Invalidate

What am I doing wrong? I only get the Panel background as it was!

[EDIT] Can it be that a ListView cannot be converted into a canvas, showing the visible items on the list?
[EDIT2] Apparently it can be rendered to a canvas...

void  draw(Canvas canvas)
Manually render this view (and all of its children) to the given Canvas.

The problem in the animation is that it takes a snapshot and then scales it. Doing the same thing yourself will not help.

You can break the animation into two animations (use CallSubPlus to start the second animation). It will look better.
