Put a progressBar on ActionBar

Question

I am trying to put an indeterminate ProgressBar on the actionBar. I was using an actionView to put the progressBar like Google+ app for example.

<item     android:id="@+id/menu_progress"     android:actionLayout="@layout/action_progress"     android:menuCategory="container"     android:showAsAction="always"> </item> 

the problem is that the progress bar is considered as an item and therefore on a Nexus S portrait mode I have only one other item on the actionbar while on Google+ I can see two items plus the progressBar. How is it possible to put a progressbar using the android actionbar?

NOTE: The functionality below is now deprecated in the Support Library.

You need to call

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS) 

in your onCreate() before setting the activity's layout:

e.g.

@Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);     ... // set layout etc 

If you are using the support library replace requestWindowFeature with supportRequestWindowFeature

And then call

setProgressBarIndeterminateVisibility(true); 

on your Activity whenever you want to show the progress spinner.
