Hi, i would like to know whats the cleanest and better way to implement autorefresh (async) on a ListView in android.

Sometimes users are checking the info in the listview and in the meantime they get an update via service.

How to display to the current ListView?
Does this envolve a service requesting the update every time?

Any clean aproach would be great to receive.

Hi JavierVera,

Are you talking about the similar to facebook feed? (This is for Manual Refresh)
If Yes, in that case you have to use  pulltorefresh and ScrollListener concepts in the app. There are many Pull to refresh library available for android.

Or

Are you talking about the "Auto refresh"? (This is for Auto Refresh)
Then, You need to add iteminfo from ArrayList from Adapter and call notifyDatasetChanged() , When you call notifyDatasetChanged() method it will refresh your listview with ArrayList with updated data.

Also see some ref stuff over here below.

Ref:
1) http://stackoverflow.com/questions/23124414/android-auto-refresh-when-new-data-inserted-into-listview
2) http://androidadapternotifiydatasetchanged.blogspot.in/

Hope this will help you.

Thanks & Regards,
