ExpandAnimation not smooth the first execution

[kikoso]

Hello Udinic,

Thanks a lot for your OpenSource contributions :-). I have been dealing with the ExpandAnimation, and it seems that the animation is not smooth the first execution (but completely fine on the subsequent ones). Is this a known issue?

[Udinic]

Not that I know of.

Which device are you using? If the problem persists - you can probably optimize the animation by allocating stuff prior to running the animation, thus making it smoother.

-GTI9001 2.3.6
-GT-N7100 4.1.2
-GT-I9100 4.1.2

Since it is involving different versions I believe is a general issue with the animation. The first time the animation is performed there is an abrupt "jump" to an state that should probably be there half of the animation. Here there is a video: http://youtu.be/X7DXWxUzlP4

The same problem also appears in those device when I execute the Android UI Patterns Application, where your example is included (so not a problem of my code customization).

So there's probably a way to optimize it for the first time.

You're welcome to give it a try and suggest a pull request when you succeed.

Cheers,

I had this aswell - it depends on your used margins (I guess you changed the values?)
Higher the one in the Animation and you will receive a smooth expanding.

Hello @mammuth .

Not really, I haven't changed the value. Modifying it again does not appear to change the behavior (which is actually right during the second execution).

This is not fixed!

Having the same issue!

Fixed by changing the visibility from Gone to Invisible.
Basically Gone will not draw until is Visible or Invisible, so first takes time on drawing and you see a jump. By changing to Invisible, it gets draw at start.
