Question

The iPhone has this swirling icon, which you can make appear when the Internet is working behind in the background. It’s a VERY simple call to turn it on/off.

Does Android have anything like this? How do I call it and how does it work?

Answer 1

You should display this in the ActionBar.

The simplest way

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

Or using ActionBarSherlock for backwards compatibility

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