[android-developers] Re: Weird problem with ListView
Hey John, First off I like the styling you have on your list. I ran into a problem like this before. I definitely second the idea of listview recycling. two things that might help. One I assume you are using an EfficientAdapter, I was. Try swaping the adapter for an array adapter just to see if you still have the recycling problem. Second look over all the Ids on different lists and the components that make them up. Make sure there are no duplicate names that is causing the recycling problem. Hope this helps, Eric Harlow On Sep 28, 7:51 pm, John Gaby jg...@gabysoft.com wrote: I have a ListView which presents a table of items.

[android-developers] Re: Weird problem with ListView
Hello John, I really like the look-n-feel of that list. I agree with the idea that this is a recycling problem. I think I ran into a problem very similar to this. Two things to check. First are you using an EfficientAdapter that stores id lookups in the tag? I remember I was. try switching adapters to say an ArrayAdapter to see if the problem disappears. if the problem does check the Ids on lists and the components that make up the list content. You may have some identical names which causes trouble when recycling. Hope this helps. Eric Harlow On Sep 29, 10:02 am, John Gaby jg...@gabysoft.com wrote: That was a most informative video.

[android-developers] Re: Weird problem with ListView
Hi John, Although I don't have solution to your problem but I am trying to learn how to make a list view similar to what you have done. I am basically not able to understand how I can get that extra line below the first line in each list item. Do you think you could share sample code or help me out?
