android - Images in ListView search results -



android - Images in ListView search results -

i have listactivity launches task nail web service , display results in listview. each 1 of results has image id attached it.

i wrote method image ids of rows displayed on screen (firstvisibleposition() lastvisibleposition()) , launch task query web service images display items. phone call method when list's scroll state becomes scroll_state_idle. makes user can scroll , task images visible rows not execute until scrolling stops, preventing looking images off-screen rows.

my issue when results show in listview, can't find way phone call method image ids query for. apparently, calling method right after calling setadapter not work (i'm guessing because of listview's work happens asynchronously). using multiple adapter's (for reasons not pertinent post), need way of waiting list items show before phone call method ids.

any ideas?

after you've set adapter or called notifydatasetchanged() on adapter, add together "load images" code list's post queue runnable:

list.post( new runnable() { @override public void run() { //do stuff } });

android listview
