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?

Answer 1

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.
