listview

Hi,

i have the following problem. I fill a ListView with a custom ArrayAdapter with data from a BD. However, in background, i'm updating those datas from the info provided by an API, so the idea is when the update finish, the adapter shows the updated data instead its "old version".

The problem is that when i do that, i notice a lag while the adapter is updating itself. Is the any efficient solution to avoid this?

Thanks
