Hi, as i see it is not possible to add event AnimationEnd for AnimationDrawables.
Is there any way of triggering a SUB after AnimationDrawable finish its job?

Unfortunately, no listener is available for an AnimationDrawable. Possible workaround (if OneShot = true): check with a timer whether the animation is running.

Hi Frédéric,

I just made a donation for this your great job.

I have a question, why in methods you did not enter a description of each arg?
It would be much more comfortable to work with.

Thanks a lot for your donation and happy new year !
Some arguments are defined in the Animation class and I don't have its source code (my class extends this class so I inherit the methods and properties of the ancestor class).

I imagined such a thing. Too bad

New version v2.2 (donationware):
I added two drawables useful for animations:
- ClipDrawable: drawable with automatic clipping (ideal for progress bars)
- LayerDrawable: multi-layer drawable

*** Not Animation Plus, in underlying Animation as well ***

Fred,

Ignore Everything I wrote, as I woke up, tried again with straight animation library, and get the same thing)

The problem was my MyTab panel... it gets redrawn at the end of the animation in original location, prior to the animationEnd call, thus getting a screen refresh when it is moved. Still don't know why the whole screen would "flash", or why I have to set the Panel's position to 0 before calling the animation, but at least it looks good now!

********* Ignore Below **************

when using the AnimationPlus to animate a panel into and out of view, the out works great (caveat, this is when I was going to approx 10% left of the activity, when starting in the middle, it "jumps" to the right when pushing in... it's in the sample code) ...(new Note, if I set asview.left to 0 before starting the out animation, then it is smooth)

However, if the panel is off the screen, I need to set the Panel.Left to 0, then start the animation, otherwise, it either doesn't animate at all, or if "enough" of it is on the screen, it will then animate, but a gap will be left if I do not set the panel.Left to no greater than the final position. And if I don't set it 0, then there is a "jump" to when it finishes the animation.

But, if I do set the panel.left to 0 before starting the animation, it will be smooth as butter sometimes, and then others, there will be a "flash" as if the display is drawing the panel all the way left, and then draws it back to where it should be.

Wondering if you can tell what I'm doing wrong?

Here is the initialization stuff:

Code: Copy

Dim tempWidth As Int
      tempWidth = vActivity.Width
      
      If bRightSide Then
         animPlusIn.InitializeTranslate("animIn", tempWidth - AsView.Width, AsView.Top, tempWidth, AsView.Top)
         animPlusOut.InitializeTranslate("animOut", tempWidth - 1dip , AsView.Top, tempWidth - AsView.Width, AsView.Top)
      Else
         animPlusIn.InitializeTranslate("animIn", AsView.Width, AsView.Top, -AsView.Width, AsView.Top)
         animPlusOut.InitializeTranslate("animOut", -AsView.Width, AsView.Top, AsView.Width, AsView.Top)
      End If
      
      animPlusIn.Duration = animspeed
      animPlusOut.Duration = animspeed
      animPlusOut.SetInterpolator(animPlusOut.INTERPOLATOR_LINEAR)
      animPlusIn.SetInterpolator(animPlusIn.INTERPOLATOR_LINEAR)

and here's the call

Code: Copy

   If bRightSide Then

      
      If AsView.Left >= vActivity.Width Then
         AsView.Left = 0
         vActivity.Invalidate
         
         animPlusOut.Start(AsView)
         animPlusOut.Start(myTab)
      '   AsView.Left = vActivity.Width - AsView.Width
      Else
         animPlusIn.Start(AsView)
         myTab.Visible = False
      End If
   Else
      If (AsView.Left+AsView.Width) <= vActivity.Left Then
         animPlusOut.Start(AsView)
      Else
         animPlusIn.Start(AsView)
      End If

   End If

(the cHTabPanel is where the code lies, it is triggered in the MyTab_Click, and the AnimationPlus is set in the StartTabPanel call)

Hi Informatix,

I am working on a google+ lookalike cards using panel + animation plus. I managed to make the panel animate during the add card. It works using scale+decelerate and I planned to use translate+anticipate to hide the card when user swipe on the panel. However, I can't find the documentation to set the original location (X,Y) and destination location (X,Y) for the translate animation to move the card-panel towards the right of the screen and eventually disappeared (hide).

P/s: where can I find a documentation of the parameters?
AnimPlus.InitializeScaleCenter("AnimPlus", ?, ?, ?, ?, view)

Thanks!

The functions with no description are directly imported from the Animation library, so you'll find their parameters and documentation in this lib.

Aha... got it. Thanks! I love your works very much and use your libraries extensively in my app. Shall donate when I start to collect $$$ and keep up the great works.

Informatix · Aug 1, 2013

Thank you for your nice compliment.

KDHeard · Aug 22, 2013

Hi Informatix - thanks for the Freeware library. I love it.... Keep up the great development work!

Hello everybody,

Here's my new baby. The AnimationPlus library extends the Animation library by adding:

the interpolators (Bounce, Accelerate, Overshoot, Cycle, etc.)

two parameters:
PersistAfter (boolean): if True, the animation does not revert to its initial state
StartOffset (long): delay before the animation really starts

AnimationSet (animations on the same view are played together)

four new Drawables:
AnimationDrawable: image-by-image animation
ClipDrawable: drawable with automatic clipping (ideal for progress bars)
LayerDrawable: multi-layer drawable
TransitionDrawable: cross-fade between two drawables

for translation animations:
PauseTranslation/ResumeTranslation/IsPaused: new functions to pause/resume the animation
AnimationRepeat: new event

List of properties and methods

v1.0: Freeware.
Interpolators, PersistAfter, StartOffset

v2.2: Donationware.
Interpolators, PersistAfter, StartOffset
Pausable translation animation
AnimationSet
AnimationDrawable, ClipDrawable, LayerDrawable, TransitionDrawable

Starting from version 2, the AnimationPlus library is released as a donationware. That means: if you want to use it in your application (or reuse a part of it in any piece of software written in B4A or Java), please donate something by using the link in my signature. I'll send you the file as soon as I receive your donation.

You can donate what you want, from one dollar to one million dollars (for such an amount, you'll be my friend forever ).
I don't do that to earn a lot of money, just to be rewarded for my work (and I probably won't earn a lot of money this way ;-)).

I've tried this workaround but the animation IsRunning method always return true even though the animation is already finish. (AnimationPlus V2.2.1)

Indeed. I'm afraid there's no mean to know when the animation is finished. There's no event for this view.

Informatix · Oct 7, 2013

I've found a way to detect the end of an animation (by comparing the current frame to the last frame). I will send the new version of AnimationPlus tonight.
Message to the first donators: please send me an email with your email address because I'm not sure that you (the first donators of this library) are in my database.

It's possible the insert one method called "Tag" (string) in AnimationPlus?

What do you want to do with it?

Vincenzo Fabiano · Nov 12, 2013

I need it to anchor one value for every AnimationPlus Object.

Ex:

AnimationObject(Counter).InitializeTranslate("AnimationEnd1", 0, 0, 0, -600)
AnimationObject(Counter).tag = Counter
LabelAnchor(Counter).ecc ecc

I need refer a Counter specific for the item when AnimationObject(Counter) is finished.

Sub AnimationEnd1_AnimationEnd
Dim Animation as AnimationPlus
Animation = Sender
Animation.stop(LabelAnchor(Animation.Tag))
LabelAnchor(Animation.Tag).RemoveView
end sub

Tag = Counter
