HI,
When trying to show more than one animation at the same time sometimes one of the animations "hickups" and just seems to jump right to the end position.
What im trying to achive is have a Gallery baseed mebu that changes the current view in a ViewFlipper, the Gallery changes the current view on the setOnItemClickListener.
if i don't use the event to chnage the current view then my Gallery animation works as expected.
if i try to chnage the view then the ViewFlipper animation works but the Gallery animation is choppy.
Any advice as to the correct way for mutiple animations?
Thanks,
If you have two Animations and they are supposed to run at the same time and are grouped together then you should combine them into an AnimationSet. You can only do this if you have access to all the base Animations. If you are using the built in Gallery animations then I'm not sure what you can do about it.

I am trying to have a calendar flip animation on a view. I have looked many examples but i got more confused.
I need to create an animation - Flip a view and show another one.
If you want to implement a calendar flip animation in a flip card manner, you should try using this library.
https://github.com/emilsjolander/android-FlipView
It gives you a general way to do it. You can always extend it further to for finer implementations.
There is a standard ViewFlipper component in Android. It extends ViewAnimator so you should be able to animate it if it doesn't do that by default.
Just to notify that I've developed a new library FlipView that includes basic flip animation and extends ViewFlipper. I mean a fully customizable library where you will be able to swap any kind of views and layouts with any kind of animation and shapes you desire, included the Gmail image flipping.
It differs from the library provided by danialzahid94. Mine is just a simple View not a ListView. By the way at time i write, ListView has been replaced by RecyclerView.
Please have a look.
I am making a game in which I have 5 buttons, looking like clouds, falling from the "sky".
That means that when my activity starts, 'clouds' cannot be seen, since the marginTop is set to -100dp.
From that position they start falling down untill they get lost on the bottom side of the screen.
The thing is, I need those buttons to be clickable, during the process of animation.
So far, I found some documentation about how I can make the buttons clickable AFTER the animation ends. But I don't need that. I need to be able to click on the buttons through the animation time itself.
NOTE: I need something that works with versions before 3.0.
Anybody has any link to documentation or some example or anything ?
After doing some research, I found out that there are two types of animations:
View Animation and Property Animation.
The view animation can only animate View objects. It also lack a variety of animations, since it can do only stuff as scale, rotate, move... It cannot change background color, for example.
Also, the disadvantage of the View Animation is that it only change the position of where the View object is DRAWN. Physically, it still stays in the same position.
That's why the button is un-clickable, after the View Animation is finished upon it.
Property Animation, in the other hand, can animate both View and non-View objects and it doesn't have constraints as the View Animation.
When objects are moved, for example, with the property animation, they are not just drawn on some other position on the screen, but they are actually MOVED there.
Now, Property Animation is a lot more complex to write than the View Animation, so if you don't really need all the advantages of the Property Animation, it is suggested to use View Animation.

You can change the buttons to imageViews and then do
imageView.setOnClickListener(myListener)
then set myListener to do whatever you previously wanted to happen on the buttons onClick. Your activity will have to implement OnClickListener
Added bonus: you can make the images look like clouds :)
Is it possible to flip a view in ViewPager.Basically i want to put several views as in hompage and a view behind every view i.e user must be able to flip the view too.
Yes Very Much Possible.
You need Rotation Animation
Look here
How to make a smooth image rotation in Android?
and

I used the above and implemented successfully what you are asking.
Look for its example in api demo of android
I basically have 5 text views that fill in one on top of the other. Rather then just all showing up like they do now, I want them to all come in with some animation, one after the other. Anyone have a link to a tutorial on how to animate TextView objects? only one I saw in the android docs involved using images as well as needing an image in the background.
Animating a TextView is basically like animating any other view. If you want it to show up one after one, you can implement an AnimationListener and start the corresponding TextView when the previous has finished.
I started with a simple animation on button,
I am successful to an extent,
The problem i am facing is, I am able to animate the button but the position of listener,
Even after button is animated the clickable area is not animated , It is resting at the original postion
Could some one help me with an useful code snippet or suggestion
Regards
Android animations can not change the layout of buttons or view in general. Only their image will appear to move, but they will stay in the same place. After the animation is finished, get the Layout parameters through View.getLayoutParams() and change them.
