Answer 1

Styled ANIMATED indeterminate progressbar icon on ActionBar:

1.Define res/values/styles.xml (This example uses Sherlock library to provide actionbar in old Android versions so, if you arent using Sherlock you should use appropiated parents to define your custom styles):

2.Define res/drawable/progress_indeterminate_custom.xml:

3.Above code uses 2 images (ic_progress_logo1 and ic_progress_logo2) as custom progress indeterminated icon. You can use as much images/drawables as you want by adding new item elements. Also, you can apply differents effects/animations. More info here: Animation Resources

4.Apply style you've created using AndroidManifest.xml:

5.Enjoy your animated custom progress indeterminate icon :D
