ProgressBar in an ActionBar, like GMail app with Refresh

Question

I would like to do the same thing than the GMail application on Honeycomb tablets. When you click on the Refresh button, the icon is replaced by a ProgressBar. How can I do this

Answer 1

Use the following layout as the action view for the action bar menu item.

actionbar_refresh_progress.xml

Then

menuItem.setActionView(R.layout.actionbar_refresh_progress);

Works across Gingerbread and the rest like a charm. Note that I have used dimension from support action bar for compatibility. You can use @dimen/action_button_min_width instead for ICS and up.
