Thank you for your reply,
First of all i called async task to load image from url,at that time while loading image scroll was strucked(up/down), after that i applied image loading lib like Picassa and nostal image loading lib etc, no result at all, I Observed gmail/facebook/twitter home page shows number of user images , profile details etc including very smooth and fast scroll .
Iam unable to guess how they developed that.Please suggest me how can i impress the end user by giving such smooth and fast scroll in the newsfeed page.
Thanks in advance

I am new to android,I have task to do the functionality exactly like Facebook/twitter news feed page. In this page i have to load user images, user details comments etc, and scroll should be very smooth and while reaching end of the page have load more items, I applied list view for this , but the problem is scroll performance is very very poor.Any body please suggest me how can i do this task. Thanks in advance.

Hi to all

I have task to load more items while scrolling down list view.List view items contains images , titles etc.
First of all i used only list view to load more items , it was successfully worked, but the scroll experience is the very very poor, so to scroll fast i kept list view inside scroll view.Now the problem is while scrolling down list is not able to load more items. I applied so many solutions but all are failed. I am searching for this past two days.if anybody knows the solutions for "Load more items using list view inside scroll view", please help me
Thank you.
