I would like to put a progressBar on the action bar but setting
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); setProgressBarIndeterminateVi
For ActionBarSherlock you can change the indeterminate progress by parenting the Widget.ProgressBar.Small, this should work without Sherlock as well.
I fetched the drawables from the android-15 res folder in the SDK, be sure to grab progress_small_white.xml and associated resource.
