How to create a listview in android so that when I want to click on of the list items, it expand to show more details?
Just override the methods below
setOnChildClickListener(ExpandableListView.OnChildClickListener onChildClickListener)

I have a ImageView with a TextView and Button. I have it currently in a custom list view, but I noticed now that I don't need to show more as one element (object). So I actually don't need a Listview to show the row (list entry). How can I show the list entry without a Listview?
You can put the elements of your custom listview item into a Layout, e.g. LinearLayout and simply add it to your activity's layout where you needed it.
You can set an OnClickListener for that layout, so user can click the whole thing.
I think you should use ListActivity. Then you can set up empty view for list. Here some tutorial: ListActivity and ListView Tips.
Also you can implement that logic with Recycler view by yourself or use library.
Here is solution from stackoverflow
In my android application I want simple list which should be initially blank when I add item it would my root list item. Further, when I add more item in that list it all should be under that root list item and it should keep number of item added under that root list .
How can I achieve this?
Have a look this answer listView dynamic add item
In this code we are add data at run time.
first of all we set the an empty adapter to listview after that at run time we add the new item on button click
If you want nested items then your best bet is to use the ExpandableListView http://developer.android.com/reference/android/widget/ExpandableListView.html
If you want more than one level of nesting then I do not believe there is anything out-of-the-box to achieve this.
Just use an ArrayAdapter to show items on the list.
When you need to add items just add them to the array and call notifyDataSetChanged();
On click of certain listview items, I need to show sub item under the item clicked.
Could some one please throw some light on this?
If you are talking about Expandable List then just look at this example.
ExpandableList1.java
Also this ExpandableListView
You can try out an ExpandableListView in Android.
I have a View with a ListView appended, which actually uses a custom view item done programatically. Inside each list item I have a button which I need to track, to update another item in the view. It is only invalidated when you click on the list item button, not anywhere else in the list item.
So I thought of creating a custom Listener. I trigger it when the button is clicked, but I have no way to access it from the ListView activity.
Is there a way to simulate those setOnItem...Listener's using a custom listener? Thanks in advance
Please see this link to help with how to set onClickListener from within custom ListAdapters.
You can use the myButton.getTag() and myButton.setTag() to put and get data to/from your View/Button.
See this link as well to help with custom ListAdapters.
Here is another good example I found of how to use a custom adapter.
I have some tabs on the top of the screen.Below that theres a ListView.
My problem is that,I want to set an item "Go To Up Folder" on the very beginning of the ListView and that should be look alike a ListView items.
You can use ListView.addHeaderView() method.
