here shared example

it seems gridview's onscrolllistener can not dx , dy. gridview's setonscrollchangelistener can requires api level 23.

i suggest use recyclerview gridlayoutmanager instead of gridview, easy use.

mrecyclerview.addonscrolllistener(new recyclerview.onscrolllistener() {     @override     public void onscrolled(recyclerview recyclerview, int dx, int dy) {         if (dy < 0) {             // hide layout here         }     }      @override     public void onscrollstatechanged(recyclerview recyclerview, int newstate) {         super.onscrollstatechanged(recyclerview, newstate);     } });
