android - How to sort LinearLayout's children programatically -


i have linear layout horizontal orientation has few imageviews in (hardcoded in xml). have sort them based on multiselectlistpreference (all checked first , unchecked later). put checked ones in beginning tried

((linearlayout)imageview.getparent()).removeview(imageview); ((linearlayout)imageview.getparent()).addview(imageview,0);

and did nothing unchecked. gives me "the specified child exists. must call removeview(view) on view's given parent" though i've called it. may because imageviews present in xml. how can obtain desired arrangement of child imageviews. if @ linearlayout not suffice, should use recyclerview here , heavier?

cast parent view viewgroup removeview method work.

((viewgroup)imageview.getparent()).removeview(imageview);

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
