How to change size of ListView rows

I have 2 ways of displaying ListView data. I have a class for each type of row. I do not create the rows in开发者_JS百科 an xml layout. (Each row is derived from View and does custom drawing).

When I switch from 1 type of row to another how do I get the ListView to layout properly with the correct row heights, and refresh?

Is View.forceLayout() on the right track?

Thanks, Gerry

do you use adapter to fill your ListView? In my code i have some adapter and when i have to change row type i set adapter to null and then to new adapter type.
