private Progre         


        

Answer 1

I tried all solutions listed, they did not work. Turns out... the real problem was my code was busy running, essentially blocking the UI thread. So the proper solution which instantly fixed the problem was... put my busy code inside an async task.

In my case I was loading several thousand record from XML into a SQLite database. Naturally I wanted to update the progress bar. Code that should have done this ( prg_bar.setProgress(iProgressPercentage) ) did nothing, and at the end of the load, the UI finally got a chance to run. Poof, progress bar goes from zero to 100.

Same code put into the onProgressUpdate() of the async task, wrapped around the same functional code, worked perfectly. This makes me very skeptical of the idea "that there's a bug in the progress bar code" and that setting the max and to zero or any of those things were ever more than a coincidental work around.
