Lazy load of images in ListView
But I'm not getting how to display the parsed data in ListView.
Thank you

This is what u should do..
After parsing the data create objects for each row in listview(i.e,use a Custom Class)
Iterate through all the objects
Add to listView Adapter
Use listview.notifyDataChanged() function everytime.
This should do the trick..;)
By using the BaseAdapter, its possible.Inflate a layout that have textviewand Image view in
Listview row.
Please look in below link for the tutorial. i am sure you will get to resolve you problem on your own

I want to show some text and an image in each listview element in my Listview. But the text and the image are actually stored in a MySQL database in my server.
I've figured out how to download the text and image pair from the MySQL database on the server. Can we create an dynamically updating ArrayList which is fed to a CustomListAdapter? Or is there any other way to show the ListView items similar to a Facebook News Feed?
Note: The image and text for each listview element would be downloaded in the background.
Create model class With Bitmap and String and create an ArrayList of type Your model class . Now retrieve data and set model class with bitmap and string and put this object into arraylist and fed this areaylist to your custom adapter . Will work . Hope this helps!
After change in your ArrayLists, you need to call
adapter.notifyDataSetChanged();
to see the changes in the ArrayLists reflected in ListView.
Now download, update the ArrayLists supplied to adapter and call the above method whenever you want in the app based on how your functionality is expecting the ListView to refresh.

First you have to make a custom ListView adapter by extending a BaseAdapter and secondly you want to get images in Bitmaps.
here : http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html you have an optimized ListAdapter
and here: Dynamically populate Android ImageView with outside resources you have a clue of how you can download an image and put it into a Bitmap (after that you can put it on to your ImageView)
How do I implement a listview which displays images an text dynamically from the web? Each image has some descriptions to it and I need them to display correctly in each list. The images change every once in a while. So I have to retrieve up to date contents.
I have read this, but have no idea how to include text into it. Any help here?
Thanks.
Here you will find full details and along with Full working Source code
Android lazy image loader example
Use an ListView Adapter like here: http://android.amberfog.com/?p=296.
The getView Method is executed for every row of your ListView, so you have to place your code to load the images right there
When the Data changes simply call notifyDataSetChanged on the ListView Adapter and the ListView will refresh (executs getView again).
