Google app style.

Add an option to have only the refresh image be pulled down, and not the view inside. Like in Google's apps. only the circle is pulled down.

I would be more then happy to contribute this feature.

The issue names no files, tests, or entry points; begin by locating the Android pull-to-refresh component and its existing refresh behavior. Confirm how the option should affect the indicator versus the view, then define a reproducible interaction that demonstrates the Google-app-style result.
