Declare your method with static key word

public static void setListMovie(ArrayList<Movie> newMoviews) {
listPresident = newMoviews;
}

and should declare listPresident as static variable

so i have to make it static like this 'private static ArrayList listPresident;' ? – Qube May 18 '19 at 09:48
yes because if you are declared variable or functions as static, it's functioning as part of class,not a member of class – Rajasekaran M May 18 '19 at 09:50
but you have to avoid static variables because they hold memory even you closed app. – Rajasekaran M May 18 '19 at 09:51
so it must be static? – Qube May 18 '19 at 13:44
Yes @qube, because you can't access non static variables in static method – Rajasekaran M May 20 '19 at 04:53
