Mark has been repeatedly saying don't call getview
Adding to it, your call to adapt.notifyDataSetChanged(); is what's going to
trigger a getView() call for each of the items visible in your list. So some
internal code in listview widget is what's going to call getview, not the
user(you). However
Okay like where do u gets getView I dont see that function in the
Listview class or the adapterView class so im not really sure where im
suppose to be able to call getView.

ArrayAdapter but what i tried this before during the
i called the adapter i used
ArrayAdapter adapt = new
ArrayAdapterString(this,android.R.layout.simple_list_item_1 ,
songs);

Of course. Again, ordinarily, you do not call getView().
You are going about your problem in the wrong way. You are attempting
to change your UI directly by grabbing some row out of a ListView and
changing it. That's not going to be reliable at all, since that row
might not exist. Rather, you
Admittedly, I haven't read this thread in detail. It seems to me, that using
an MVC approach is called for. The controller (the click handler) shouldn't
be calling the view directly. The controller should call the model. The
model will update the view accordingly.

You need to do setText in your implementation of getView. In the item
clicked, store your state and call notifyDatasetChanged (check the exact

Its probably a bad idea to play with any View managed by the Adapter
other than the one that is passed to onItemClick() or to getView().
So the idea that you find view + 1 is not going to work. There is
lots of tricky View pool activity behind the scenes so you can't make
any assumptions about
