Yes i took help from your code.The popup which is floating upwards is a layout of the same type as the layout being used for the ListView.

Hats off to you man ...you are a life saver.
Although the animation with this code is not smoother like the one in the
video but its as smooth as it can be and its good in terms of lines of code
and other unnecessary stuffs i used to achieve. check this out and provide
me your feedback

Thanks for replying again. * * * you can override its height in the getview() and set it at 1 dp high (tip: don't set the row view to View.GONE). At the end of the animations you will just be fiddling around with row heights and view contents so you shouldn't need the notifyDatasetChanged().* * * I could not get you by setting it at 1 dp high.And what i need to do after animation ends?Please explain little more.

[android-developers] Re: Animations in the list view
in that case I'd think about insert a new row into the list when the listview is first displayed. from the example its always going to be at position(0) in the list so you can override its height in the getview() and set it at 1 dp high (tip: don't set the row view to View.GONE). At the end of the animations you will just be fiddling around with row heights and view contents so you shouldn't need the notifyDatasetChanged().

Hi Nick , Thanks a lot for your reply. I did the same you suggested but it had revealed few issues: after implementing all three steps and when i did below step also *- After the animations have finished insert a new Row into the List at the insertion point, change the child view height back to a single row height and destroy the dummy row view.* * * *-*when i inserted Row into the insertion point and called notifyDatasetChanged for the list to update the row it showed some jerk because list's getview method called and repopulate the list again and i needed not to change the child view height back as getView changed its height back to original.Animation was not that smooth as its in the youtube video. If i misunderstood your stpes ,and if possible ,could u please create a demo project and send it to me to yourans...@gmail.com.I ll be grateful to you.

[android-developers] Re: Animations in the list view
I think this is not very different to a question we had a couple of weeks ago. This is what I would do: - I would not use 2 ListViews. I would leave the original ListView underneath and dynamically create a new View that was a single RowView and put that on top and slide it around. - I would not insert an extra row into the original ListView. Instead find the child view at the top of the list and double the height of it. Make sure the gravity of the content is such that is sticks to the bottom of the view. - Slide the dummy row view up until it lies directly over the top (blank) part of the child view. - After the animations have finished insert a new Row into the List at the insertion point, change the child view height back to a single row height and destroy the dummy row view. I think that should give you the appearance you want. Judging from the neutral background and lack of row dividers I'm guessing whoever wrote the sample behind your youtube example did something similar.

I have tried one way of doing this kind of animation.I have taken 2 listviews and made first list view's visibility gone.Then i have taken one separate layout( the same custom layout i am using for the listview )and trying to translate that layout from middle to top and once it reaches to top and making it's visibility to gone.and the same time when the view is translating, i am sliding down the list also and once the view's animation ends i am setting list animation to fillAfter = true and fillEnabled=true and list1.setVisibility = gone and list2.setVisibility = visible sothat list2 should be visible but what happening is list1 is not getting gone it still be there because of the bug when we use fillAfter = true and fillEnabled=true.How can i make my list1 visibility to gone ?

[android-developers] Re: Animations in the list view
The quick and incorrect approach would be starting these growing animations from your ListAdapter's getView method. Right before you return the convertView you'd start the animation object on that view. However, there is a problem with that animation approach because ListViews lays out its child views (items) and determines their positions. So using an Animation object for transforming the height of an item (grow animation) would not affect the other list items. They would statically remain in their locations and your new item that slides in will just grow into a gap that is exactly that item's full size. Following solution ideas: - You override ListView and add some layout animation behavior that does what you need - Animate the height of your added item using a Timer object. Trigger re-layouts of the ListView in order to align the other child views accordingly. (However, I don't know whether you'll need to constantly invalidate your listadapter in order to make that work. This might turn out to be a pretty wasteful approach!)
