android - Using Google Design Library how to hide FAB button on Scroll down? -

google have released design library, using

 compile 'com.android.support:design:22.2.1' 

however cant see code examples of how use library , how animate fab bar on scroll. guess can listen scroll events on listview , animate button myself, not baked api (is not point of support library).

is there examples ?

thanks

if you're using recyclerview , you're looking simple, can try this:

    recyclerview.addonscrolllistener(new recyclerview.onscrolllistener(){         @override         public void onscrolled(recyclerview recyclerview, int dx, int dy){             if (dy > 0)                 fabaddnew.hide();             else if (dy < 0)                 fabaddnew.show();         }     }); 

by replacing 0 constant, can adjust sensitivity of triggering, providing smoother experience
