Android Question update list every 5 seconds

Hello,

I have a list with around 1000 entries which updates every 5 second with httpjob's received data. I use a scrollview and add labels in it to achive that. This freezes the app for a second with every update. Is there a way to do it without making it freeze the user experience ? ( if the user is typing stg while the update processes , the textfield freezes for example )

Thanks
