We are using list view in our app with one simple row layout.
But on click of list view we want to change the row layout of
tht particular item . is it possible to do ? wht is the best approach ?
Ho to add listeners to view inside the row layout?
To do something like that you are going to have to write a custom
adapter... When the listview item is clicked you then set the clicked
status on the adapter for the clicked item, call notifyDataSetChanged() and
let the getView() method handle the change...

There is no way that you do it with the adapters that already exist. You have to create your own. The adapter's getView method is responsible for creating and displaying every single row. Let's suppose that you need only two row layout to switch with. In that case the model used with the adapter could have an attribute to tell if it is using row type 1 or 2. In the onclick you change the model of the clicked item, you choose its row type and you notify that the data have changed with notifyDataSetChanged().

we are using a custom adapter only. in the adapter in getview method we
are setting a tag for the first time. "isSelected" as false
and on click we change the tag value as true and invalidating the listview
with invalidateviews. so we are making ui changes in the row layout based
on this tag value. But the problem we are facing now isif i click on first
item the change happens on some other row layout. some problem while
reusing the layout we guess. any one have any idea regarding this.

Don't do it this way... Do it the way I described in my first reply to your
question.

Justin Anderson , how to set clicked status on the adapter for the clicked
item ? Can you explain a little bit more if you don't mind. It will be a
great help for us.
Thanks ,

What he means is that you should add a boolean in your data model for list items and use that instead of setting a tag in the view. What you are doing is storing your data in your view which is wrong from an MVC point of view.
