Android Question [Solved] I'm having difficulty with Animation (AnimationPlus)

RMarra · Oct 17, 2019

I want to slide a panel to the left when a button is pressed. I created an AnimationPlus object:

B4X:

    BoatAnimation.InitializeTranslate("AnimationLeft", 0dip, 0, -130dip, 0) 
    BoatAnimation.Duration = 700
    BoatAnimation.RepeatCount = 0
    BoatAnimation.RepeatMode=BoatAnimation.INTERPOLATOR_LINEAR
    BoatAnimation.PersistAfter = True
    BoatAnimation.Start(BoatPanel1)

and I have a AnimationEnd routine:

B4X:

Sub AnimationLeft_AnimationEnd
    BoatAnimation.Stop(BoatPanel1)
End Sub

It works up until I do the BoatAnimation.Stop and the panel jumps back to where it started, even though I have BoatAnimation.PersistAfter = True

Can anyone see what I'm doing wrong?

Try this code:

B4X:

Sub AnimationLeft_AnimationEnd
    BoatAnimation.Stop(BoatPanel1)
    BoatPanel1.Left=-BoatPanel1.Width '<-- add this line
End Sub

Usualy for this purpose i use SetLayoutAnimated as follow:

B4X:

BoatPanel1.SetLayoutAnimated(700,-BoatPanel1.Width,BoatPanel1.Top, BoatPanel1.Width, BoatPanel1.Height)
Sleep(700)
BoatPanel1.Left = -BoatPanel1.Width

There is almost no good reason to use the Animation library. Use the internal animation methods instead. They are simpler and in many cases more powerful, especially together with calls to Sleep.

For what I'm doing, the internal animation is so much cleaner and easier!!! Thank you.
