How to verify page is scrollable in android native view?

I have scenario to scroll down to the page where scroll is possible and identify the webelements. Now the challenge is each time I can not perform the scroll method to identify the webelement. Is there any way to find weather the page is scrollable or not. If scrollable then do the operation. If scrollable how can I scroll down to next exact down page where I can easily identify the other new webelement which has not seen on the first time
