I've read this article http://developer.android.com/training/animation/cardflip.html and made it work, but now I want to flip like that every item in listview. Is this possible? I can't figure out how.
Now it's possible, 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 (and much more), included the Gmail image flipping.
Please have a look.

I want to create a scroll view with pages that can be scrolled vertically and horizontally as well.
The scroller should be just like a slideshow on a website, to slide between images (content). Something like ScrollView, but to stop at a certain point when scrolled.
I am using this in Xamarin.Forms, so I'll need to create a custom renderer (Android) and set the content of the pages from Forms.
I tried ViewPagers, but I want to be able to set the content from Forms page, not from predefined layouts...
I just couldn't find a clear example/tutorial so I can understand how to approach this problem. I also think about overriding some methods from ScrollViewRenderer class, to intercept and only slide to a certain point, but have no idea which methods and properties to change.
Something like CarouselPage on XF, which can be used inside a layout.
Any help or examples would really be appreciated. Thanks!
I'm searching for 2 days for a solution for this problem.
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 want to create slide in effect like below.
http://demosthenes.info/blog/838/CSSslidy-An-Auto-Generated-Responsive-CSS3-Image-Slider
The differences are
1) I have layout with two images, and when the new image is downloaded in background, one of the existing image has to slide out and this new image has to slide in.
2) User dont need to scroll and see previous images, I want to show only two images at any given time.
3) Its better if the diapered images get disposed.
What i tried so for with no luck
1) Horizontal scroll view- issues is hard to add items dynamically scroll to it while existing images been deletes.
2) ViewPager - http://developer.android.com/training/animation/screen-slide.html, couldnt get it to work.
what other ways is there, or how to improve what I tried.
Thanks

I think your looking for this.
ViewPager is what you want, hope it'll help.
I am new to android therefore I got a little bit lost with all those ViewFlipper, ViewSwitcher, ViewAnimator and ViewPager. Moreover, I am not sure what's happening under the hood.
Basically I have an activity which shows some data. With swipe (or button, doesnt matter) I would like to scroll the view and get to another page (as seen in the picture below).
Is it possible to implement something like that without changing to another activity?
I am a little bit confused regarding views and access to the design elements. How those pages are located each to another? e.g. If I am currently seeing Page1, can I modify content of Page3? Or plainly saying, are all page views loaded all together? As if I set setContentView(R.layout.xlayout); then I can access only xlayout elements.
But if I use same activity, then I have a thread there which updates a counter on Page1, if I change view to Page 2, the counter will not find Page1 Counter TextView and will complain.
As I Understand Android 4.0 has ViewPager which is similar to the seen in the picture. I am using GB. Should I use support library or can I just go around and implement something similar without importing any libraries?
(Sorry, my description is a little bit messy)
Yes, you can use ViewSwitcher, ViewFlipper and ImageSwitcher depending on your requirements.
ViewSwitcher may have two childs at max. And these child might be a View or an object of subclass of view.
ViewFlipper: May have as many childs you want. and these child might be a View or an object of subclass of view.
ImageSwitcher might be used to switch images over.
By using view flipper you can display one item at a time, and adding a gesture overlay, you can apply sliding effect. To apply View Flipper, you need to add all the views to ViewFlipper, and showNext and showPrevious methods are used to show next and previous child.
You need to use a ViewPager to have the same behaviour as in Google Play.
it only available on recent version of Android, but you can use the Compatibility Package to make it available for older version.
With a ViewFlipper you can't "scroll" between two pages.
Is it possible to animate the background image of a layout (RelativeLayout, LinearLayout, etc.) in Android? In one of my applications I am fetching an image from the internet and displaying it as the background image once it's loaded. It would be really cool if the background image was swapped out using a fade effect or something like that.
I've tried quite a bit, but couldn't seem to find a solution. It's always the layout that's animating and not the image itself.
Might be your best bet to just layer your layout in a FrameLayout or RelativeLayout with a ViewSwitcher behind it. See the demo (and related layouts) in the Android API Demos app (that uses an ImageSwitcher, which is a special-case adapter-based subclass of ViewSwitcher). It does mean an extra ViewGroup level in your app, but unless you're doing something especially complicated (nesting these in ListView rows or something) it should perform just fine, and handles the transition animations for you.
You could also just use WebImageView from DroidFu, which does most of the annoying legwork for you.
