阅读更多关于 Update ListFragment after asynctask

问题 I have two listfragment and one fragment in my application. I show you first fragment. The application starts, Asynctask retrieves data and put them in arrayNews. I think the problem is the update of listview or adapter in listfragment that does not refresh. If I change the phone's orientation => listfragment (+ listview) appears correctly. If I go to fragment 3 (fragment in 2 and 3 in memory), then come back on fragment 1 => it works correctly. Sorry for my english ^^ public class

阅读更多关于 ListView Requires 2 setSelection's to Scroll to Item

问题 Peculiar problem I'm having with a cursoradapter in a listfragment. In my onLoadFinished I select the previously selected item in order to scroll the listview to the previous position (and then highlight that item). This works splendidly, except for the scrolling part. If I just use one post and delay it (even say 5 seconds), the item gets selected but the list will not scroll (the selected item may out of view at this time) With or without delay same behavior with just one post. I have to
