I would like to put a progressBar on the action bar but setting 

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);  
setProgressBarIndeterminateVisibility(true);

on onCreate method produces a medium size progressBar (48dip x 48dip) I guess. I want to change the size of the progressBar but I cannot find how to do it. Can you help me please?

android android-actionbar android-progressbar
