Android Question Slide from one html page to another

Hi

I am making an android book app with java using one web view and my pages in html files.

I created an assets folder , under src- main and store my pages in there

Now all I'm missing is a navigation method.

As I am new to this, I am trying to find how to slide from one html page to another instead of clicking buttons. please if you know how , set an example because like I said I am new to this.

here is a link to the app I made if you want to have a look(its very small for testing purposes, with 3 pages).

So far no one gave me any reliable answer that refers to a rookie like me in coding nor I find a video tutorial that saws how to do that with html pages that are stored in your assets folder.

Thank you in advance

Philip
