I am trying to determine the best way to have a single ListView that contains different layouts for each row. I know how to create a custom row + custom array adapter to support a custom row for the entire list view, but how can I implement many different row styles in the ListView?
Since you know how many types of layout you would have - it's possible to use those methods.
getViewTypeCount()
- this methods returns information how many types of rows do you have in your list
getItemViewType(int position)
- returns information which layout type you should use based on position
Then you inflate layout only if it's null and determine type using getItemViewType
.
Look at this tutorial for further information.
To achieve some optimizations in structure that you've described in comment I would suggest:
ViewHolder
. It would increase speed because you won't have to call findViewById()
every time in getView
method. See List14 in API demos.I hope that will help you. If you could provide some XML stub with your data structure and information how exactly you want to map it into row, I would be able to give you more precise advise. By pixel.
