3rd party/ in-build library function

Hi guys,

I am trying to automate some features which are either default feature or was implemented using a 3rd party library. Is there any way to automate those features/function.

Like in Amazon app you have sorting/filter option for price range which includes a slider value from 1000 to 10000 or any price, in my App I am having same kind of slider, but by spy mobile feature I am only getting an image view, by which I can only check the visibility of the slider & can not do anything else.

It would be great help if anybody can help me on this.
