ListView and dynamic row sizes

I'd like to use different 开发者_运维知识库row descriptors (from the XML layout resource) in one ListView. Can I and how?

Also, I'd like to be able to programmatically change the size of the rows, based on the data in each row, in a ListView. Can I and how?

Thank you in advance--I LOVE stackoverflow.

Step #1: Override your Adapter class and implement newView()/bindView() (or getView() if ArrayAdapter)

Step #2: Inflate the rows you want when you want them from the layouts you want

Step #3: Override getViewTypeCount() and getItemViewType(), returning appropriate values, so Android knows to use different object pools for each distinct type of row

This book excerpt covers #1 and #2, though for only one type of row. I don't have any samples handy for multiple types of rows, sorry.

Put in bigger stuff in the row. Heights of rows are determined by their contents.
