I have a game which uses a RecyclerView to create a horizontal "Stages" view. When the player passes the current stage I want to add a simple hop animation to the view containing the "Stage" the user just passed. I've tried using normal Animations, but haven't been able to get them to work correct.
The documentation of the animateChange method of ItemAnimator sounds like it's a good place to do this, but I haven't had any luck finding good documentation on how to implement a custom animation here.
I'm looking for advice, pointer to documentation on how to create custom animations on item change, or a solution. Any help would be greatly appreciated.
I was able to accomplish what I wanted by using a CycleInterpolator

In my android app I am using a gridview. Now I would like to animate it, so that when I set the adapter to the gridview I get some kind of fade in transition.
Ideally, what I am looking for is an effect similar to the one used in this app https://play.google.com/store/apps/details?id=com.alensw.PicFolder&hl=en. There I mean the effect when you click on a folder.
Does anyone know how to achieve this? Shall I use NineOldAndroids?
You can use/integrate this

The Above link is for GridView and ListView
also you can use from these also

I have to display a list with a similar display to the pic. I've searched a lot but haven't found a particular solution for implementation.
You need to implement a custom component.
You can make your own component like that.
Here is a demo application for wheel view component.

I want to change the animation when inserting or deleting rows in listview to something simple and very easy to see what happened (insert/deletion).
I would like to see an easy and basic tutorial on how to do this. I could always change the animation afterwards, but first i just need to learn how to attach animation to listview and trigger it when deleting/inserting rows.
Thanks in advance!

That gives a pretty good way to do it. All you have to include is logic that only fires the animations when an item is added or deleted. That shouldn't be too difficult.
I need to create listview like in this picture. The listview item go over each other like google chrome tabs.. I can move up or down listview item... Could anyone tell me a good advice or tell me examples how should I do this?
Thanks
You need an iOS passbook style component like CardWalletView
You have to create some accordions type control
Here is a link which will help you
http://android-puremvc-ormlite.blogspot.com/2011/07/android-simple-accordion-panel.html
when you close the previous view you will not animate that view to the end you have to keep some margin of 2 to 3 pixels to show view as you want
Another idea is you should create some view and use drag and drop... But also you have to some Math calculation... Try this maybe you can get something
Expanding list views may help you with that. I assume that your list view will essentially expand on click and shift everything below the selected area downwards revealing only the content of that selected tab.
Expanding list views utilize the parent-child methods that would allow you to create a very rough view of what you are showing. Styling and customizing those rough layouts afterwards could very well allow you to get that look you're looking for.
Here are some links that might be useful.

Here's the basic UI i intend:
There is central circle:CENTER. As the view is rotated, new circles:NAME are generated on the circumference. The circle at the top is a newly generated circle, i.e. if an already generated circle passes the top it fetches a new name.
I don't know the Android API well enough yet, so can someone point me in the right direction? What classes should I look at? How can I create that sort of pathing? Do I generate circle programmatically or have the views already in the xml layout but invis?
Thanks.
EDIT: Currently I'm working on the custom views that will be each circle.
I think you could do it by extending AdapterView. I would start by looking at the source code for it and some of its decedents to see how they implemented them.
The functionality you are after I don't think is very far removed from a ListView or some of the other simple Adapter ready View widgets.
The main difference is going to be your onDraw() method, you'll need to override that to draw the circles for you. Whether you make the circles programmatically or define your own views in xml is going to depend on how you want to appear visually.
I don't have any sample code for the rotation effect you are after but surely it can be accomplished with a canvas and some geometry.
Once you've got the AdapterView built you'll also probably want to subclass an Adapter to hold your names and override its getView() method to populate the names into the circles for you.
If you have not ever implemented any of the ViewGroup widgets I suggest you start by exploring some of those. ListView, GridView, etc.. Learn how to use it with an adapter and some data to create the dynamic layout. Once you have a good understanding of how to use the ones that are already built then start trying to tackle the one you want to make.
