Material sidebar icon animation (e.g. Gmail)

I am investigating if there is a 15+ API to implement sidebar icon transitions as displayed on the video by google:

If I use the classic ObjectAnimator.fromFloat() the code will be huge and cumbersome.
Is there a way to reposition the items with a reasonable length of code?

Use the following library with sample.

Swipe to delete for a custom view not for list item

I want to develop a layout with a very simple ImageView and a Listview binded in a Relativelayout . Now for a better user experience I want to delete the Image view by swiping it left or right same like what is implemented in android Gmail app to delete emails.
Implementing it on a listview item is very simple and there are many tuts and sample codes are available over the internet including the official Google I/O talk on animation and explained in a very good way by Chet Hasse here
https://www.youtube.com/watch?v=YCHNAi9kJI4
but I don't require to implement it on the listview items insted I want to implement it in more generic way. In my case I want the same behaviour for my ImageView item as one view and ListView another . Like shown below
As soon as the ImageView item is deleted the whole ListView should smoothly come on the top.
I have tried many way to implement the same without any success.
Suggest me the approach or some samples to do this which is supported in Gingerbread and above android OS.

You can use this code:
https://github.com/romannurik/Android-SwipeToDismiss/blob/master/src/com/example/android/swipedismiss/SwipeDismissTouchListener.java
As described in readme this code works for android 14+.
You can use the NineOldAndroids library to support old versions of Android, or use the Jake Wharton's port:

I looked around and found this helpful.

I implemented a custom ViewGroup that takes one child and allows you to drag/fling it to the left with a callback once the swipe is complete. My intention was for it to work just like in a RecyclerView. Works well in a LinearLayout with animateLayoutChanges=true and setting the visibility to GONE in the callback.

Which layout should I use (css inline-block equivalent)

I would like to build a specific layout for an android application. Actually, I would like to obtain something with the same behavior as inline-block div in html/css... I don't really know if I should use a LinearLayout or a GridLayout or something else...
It's like a horizontal LinearLayout but when the line is full, I would like my objects to go on the next line... I'm going to add the items programmatically to the container...
Here's an example of what I would like to do:
Do you have any idea?
Thanks by advance,

Instead of using a layout, it might be easier to use a GridView because they will only use memory for items on screen and can be added using an adapter.
Read more here: http://developer.android.com/guide/topics/ui/layout/gridview.html

Android provides a GridLayout component (along with the helper view Space which can be used to build a flexible layout with multiple rows and columns, as explained in The Android Developers Blog. It is available as of Ice Cream Sandwich (v14) or as part of the v7 support library, and hence available to all 2.1+ devices.

Create Carousel Style ViewPager

I'm looking to try and implement this style pattern into my application:
http://www.androidpatterns.com/uap_pattern/carousel
But I am having trouble in finding an existing library or solution to it. Does anybody know of any libraries that I could use or how I would go about implementing this?
So far, Ive found this:
http://www.inter-fuser.com/2010/02/android-coverflow-widget-v2.html
but it isn't quite what I want as it would be nice if it was hosted inside of a ViewPager so I can have buttons etc inside the view.

You might try twoway-view, an implementation of an AdapterView (similar to ListView/GridView) that supports horizontal scrolling.
In this case, you'd use it more like a ListView rather than a ViewPager, so each element would be a separate item layout, rather than Fragment.
One example of where twoway-view is in use right now is the latest Firefox for Android nightly as discussed on the announcement post, which contains some screenshots of it in use:

Android interface : show form like the grouped listview style?

I'm building an App for Android that already exists for iOS. On iOS, we really like to use the listview grouped style to show details and forms. It is really useful to show details of objects that we don't know how much properties they have before loading it.
I know that Android doesn't have a similar tableview style. And I don't want to use a custom library to recreate it, because I don't want to force an iOS like interface to my Android's users.
But how would you create a consistent Android interface that show similar information? Do you have example for me?

First of all, your instinct to not force iOS style UI onto Android users is correct and I respect you for it.
Android's ListView is roughly the equivalent of iOS's UITableView. There are important differences. For instance, you should never use a ListView inside another scrollable container. If a ListView is in a particular layout, it should (usually) be the only scrollable component. If you want multiple ListViews in a layout, you probably don't want ListViews at all. You should instead use (vertical) LinearLayouts and add the items in order.
Cyril Mottier writes excellent posts on implementing custom behavior for Android's ListView.

If you want to display data in a list then you can use the ListView. Here is a great article about how to use it.
