Hi Guys,
I hope this tutorial might be helpful to all android developer to search or filter the item of the custom list view.
Here the list view which shows in Alert-dialog. And we can search the item of the list view.
Here I am creating the ListView and Editext programatically and search the item of the list view.
So lets start the coding to search the item of the listview in alert dialog.
You can download the source code CustomListviewFilter.
Cheers Guys!
