I need to create a listview that looks like Stack of list items .
The list should be similar to the one that we see in the Notification Bar or else it should be like most recent Apps in Android L.
Can anyone help me with idea of how to implement such type of list or some sample code fragment.
Use Base Adapter . You can define the element of list anyway you want.
Try using ListView for the UI development and implement the suitable adapter for it.
You need to have three things:
Source of data which you want to display your list view.
Fragment/UI [List View] for displaying the data.
An adapter which binds data to list view.

I have looked everywhere for examples on how I can have individual fragments set up as in a list view. It seems either this is highly not recommended or not possible. Does anyone have examples that I can look at? Essentially the app that I am trying to build is a an e-commerce app with a list of items to purchase. I know it may be overkill to have every item to be listed as a fragment but for this project, I need to do this.
This is highly not recommended. If your using a ListView then your xml layout file for each list item will be the same. Ideally if you use a ListView your elements will be mostly the same. You could have one Fragment for when an item is selected from your ListView, however. This one Fragment will be able to function properly for all elements of the ListView. That way you only have on Fragment for all of the elements in your ListView. Having a Fragment for each item in a ListView would be very inefficient.
I want to create List view row animation like below . I want to move row from one list view to other list view. Both list view are in same activity.
Anyone can give me idea how I can do this.
First of all because you mentioned "ListView":
In my opinion the best way to perform dynamic "lists" in android is to use to android-given class
RecyclerView.
It's easy to use like a normal ListView but like I said before it handles dynamic data.
Moreover it has some support librarys like ItemTouchHelper to drag/drop and swipe items in the list around. Its very easy to expand your RecyclerView with this upgrade. Here is a good tutorial:
Tutorial.
I would like to give you two ideas how I would proceed to implement such a list like the example of your post:
1) (Recommended) Search on Github or similar sites for 3rd library parties that already solved this.
2) Use the RecyclerView with the ItemtouchHelper-Upgrade i mentioned above and try to expand it with two lists. When an item is onMove() set the visibility of the first list on GONE and the second on VISIBLE. Now you only have to add the data of your item to the second list and remove it from the first. Then use notifyDataSetChanged() on both lists and your done.
I dont know how difficult it will be to implement it but thats the only way I know how you can do that and how the programmers of your example could have done it.
I am new to android, can any one post the code for the below scenario.
I have set of data like first name, last name, date and id from arraylist to the listview to display, i need to filter it through id and when i click any item in the reduced listview, i need to pass the id so i can display that particular item details seperately in another activity and i have used Custom ArrayAdapter
I have created a demo project which is doing exactly what you need,but yes,you need to extend BaseAdapter for this rather than using ArrayAdapter.
here is the whole source code,
Search on custom adapter
I hope it will be helpful !
A nice tutorial here exactly suits for your requirement. you can go through it

I would like to design an item like this that opens a subset of other items when clicked, I have only seen it in other applications I've used, and I can't find any resources on how to create it. Does anyone know how to?
Thanks.
Its not clear if you want to created Nested listviews that look like this
-Item1
-Item2
---Item2A
---Item2B
-Item3
or if you want to open a completely new list when the user clicks on an item.
If you want to use a nested listview look at this question: android nested listview
And if you want to open a new activity, then create a 2nd activity with a listview and open that on an item click
Perhaps you should try to have a look at the ExpandableListView.
Documentation is available from here:
http://developer.android.com/reference/android/widget/ExpandableListView.html
If you wanted to add a ListView that opens another list, you can do it in several ways. I've successfully done it by adding an OnItemClickListener to the ListView and then simply load a new set of data in the ListView and update it using invalidate() or by setting a new Adapter.
You could even add some cool transitions or animations, and create a listener for when the animation is completed. Lots of cool ideas :-)
Hi I am using expandable list view in my layout which contain list of fitness activities i have done on that particular day. I can see all the list of activities when i initially open my Activity. But when i add new activities, i can not see new activities in my expandable list view. How can i see my new activities when i come back from other screens? Please suggest me some solutions.
Thanks in advance.
One easy way is that after adding activity, bind the adapter again with your listview. Make sure whatever array, you bind with list view using adapter, gets updated after you add activity.
