I've designed this login form simulating the facebook login page for movil. I use web services to do requests from the app to an API:
What i want to do is putting a circular progress bar while the request is executing, i want to disable all the components, and put the cicular progress bar over the form and once the request has been attended, enable again all the components. This is my xml code:
