The View gets updated only after your method is done executing. So, when you call setImageResource() the view is not immediately updated. You should use a separate thread for your for loop, and I can think of 2 options right now:
1. Use a Thread and a Handler to update the UI ( http://developer.android.com/guide/appendix/faq/commontasks.html#threading) 2. Use an AsyncTask ( http://developer.android.com/reference/android/os/AsyncTask.html) Hope it helps, YuviDroid On Sun, Sep 26, 2010 at 10:29 AM, ArcDroid <jacobrjohn...@gmail.com> wrote: > I originally tried a separate thread, but couldn't update the > ImageView from my new thread. > > On Sep 26, 1:23 am, ArcDroid <jacobrjohn...@gmail.com> wrote: > > the first picture never loads with the while loop.
