Android Question SetLayoutAnimated not working properly ?

[JTmartins]

I have this litle piece of code.

What is happening is that the panel opens smoothly in a "animation", however it does not "animate" when it is suposed to close down.

It simply vanishes exactly as if I did pnlScore.visible=false.

What am I doing Wrong ?

Many thanks

JM

Sub igvMenuScore_Click
    If flagmenuscores=False Then
        pnlScore.Height=0
        pnlScore.Width=0
        pnlScore.Visible=True
        pnlScore.SetLayoutAnimated(200,85%x,49%y,13%x,51%y)
        flagmenuscores=True
    Else
        pnlScore.SetLayoutAnimated(200,85%x,49%y,0%x,0%y)
        flagmenuscores=False
    End If 
 
End Sub

PS - Just noticed now that If I use 1%x and 1%y it does "animate", however it does not suit my purpose as a litle bit stays there. If I do a pnlscore.visible=false, after the "animation" it vanishes without any animation (I presume because the instruction is reached a few miliseconds later, so the animation will not run.

Indeed, it is an interesting behavior:

pnlScore.SetLayoutAnimated (  200,85%x,49%y,1dip,1dip)

works like expected and

 pnlScore.SetLayoutAnimated(200,85%x,49%y,0,0)

do not....strange...

Seems like you are hitting an internal optimization of Android where it hides the view if its size is 0. This causes the animation to be hidden as well.

Use 1dip and combine it with a call to SetVisibleAnimated to completely hide it.

I have also found different behaviour between two different devices when using SetLayoutAnimated and it took me almost a day to get it sorted out...using/calling INVALIDATE. Not sure if it is relevant to the above problem but it did sort out the problem I had.
