Hi, Can any one help me to get the concept of ListView?
I would like to display list of video's link in my xml. Could you please tell me how can I achieve this requirements? If I clicks any one of videos within the list of videos then it will display the corresponding video in the same page(xml) or different xml. What is adapter... What I'll write in my Activity.java file... Layout View (Output of VideoList.xml), http://video1.mp4 http://video2.mp4 ... ... ... ----------------- | Display | | video | | here | |----------------| Can't wait for your valuable answers!!! Thanks in advance. Thanks Again!! Yasmin On Fri, Oct 31, 2008 at 12:13 AM, Emery <[EMAIL PROTECTED]> wrote: > > You're doing it onItemClick, so it's probably invalidated for redraw > anyway.
