android - How to display animation image like the Quick Search Box -

I have applied an activity that receives data from a web service and displayed in an autocomplete text Does it work quite well.

I'm interested in displaying a spinning animation while the data is being retrieved (the same effect as the quick search box)

I try to understand what QSB do (10x open source!) But no place could be found where the spinner image has been placed on the edit edit test.

If you apply the suggestion provider, the spinner tells you when the query starts.
