FWIW, I've also seen getView called more times than the number of

Don't worry about it - just make sure your getView does the right thing,
based on the item's "position".

You notify the adapter the data has changed and therefore should
redraw itself.

Patrick,
I would suggest using a custom ArrayAdapter that uses the 'view
holder' concept to manage the child views.
Also instead of using a linearlayout I would use a relative layout as
it will render faster because your layout tree won't be as deep.

Put fewer than 2300 items in the list. Design a UI that presents fe
First:
You directly modify the activity's attribute 'items' (that serves as
your data in your list-adapter) in your background thread, without any
proper synchronization with the main GUI-thread. This is bad news. It
may work for a while, but it's bound to fail at some point.

I am actually using in List3 adapter.notifyDatasetChanged(). This do

Do NOT call invalidateViews(), it calls ListView to throw everything
away. Use Adapter.notifyDatasetChanged() instead.

Hi,
I think you need to set the Onclik Listner for the ListView in the
Ocreate Method.
And also I need a help from you..!
CAn you tell me how to display Array of Strings to List.

All your message need to tell the UI thread is that a new image is
available. You don't have to pass the image as part of the message.
Usually, the background thread would download the image and put it in
memory (in a list or map for instance) and then simply tell the UI
thread to refresh the UI.

It appears that arg1 is the text in the item, but it returns in a

How can I get the nice text from this textview
I take it you don't code java very much :-).
I don't see why you are trying to get the selected item with
VList.getSelectedItem(). I think you want to just use the arg1 in my
example.
The toString() probably won't give you what you want and it would
work, but apparently o is null since you got a
Does anybody know whether that conversion from the object to string
