ListView Recycle mechanism

Question

I understood ListView Recycle mechanism very well from How ListView's recycling mechanism works but i don't understand one thing,

If i want to change height of list row then why it only works by setting height dynamically,

For example :

convertView.setLayoutParams(new AbsListView.LayoutParams(AbsListView.LayoutParams.FILL_PARENT,80));

If i define height of row layout in xml it does not change, how it is related to recycle mechanism ?

It is not only for list row height i have seen many cases where attributes of xml does not work but changing them dynamically works well, but how ?

Can you provide some examples where `setting the attributes of xml` don't work? Also where you inflate that specific item's xml layout. — Simas, Oct 10 '14 at 06:36

I understood, there was a small mistake i was trying to inflate listview layout using

convertView = mInflater.inflate(R.layout.drawer_list_item, null,false);

above code was the main reason, why attributes of xml were not working. Then i changed it to

convertView = mInflater.inflate(R.layout.drawer_list_item, parent,false);

Now it is working as expected, sorry but recycle mechanism has nothing to do with xml, i lost there.
