android - Synchronize color changing in onDraw -


i have android game. change color scheme on touch. code is:

if(rect_dark.contains(x, y)) {         isdark = !isdark;     invalidate(); }

then in ondraw method:

        if(isdark){             this.setbackgroundcolor(getresources().getcolor(r.color.black_color));         } else{             this.setbackgroundcolor(getresources().getcolor(r.color.light_color));         }           if(isdark){             mscorepaint.setcolor(getresources().getcolor(r.color.light_color));          } else{             mscorepaint.setcolor(getresources().getcolor(r.color.black_color));          }

so, when press button changings of color not synchronized. @ first background color changed , text color. eyes see that.

how deal problem? answers.

maybe improve performance enough:

private int mcurrentcolor;  if(rect_dark.contains(x, y)) {     isdark = !isdark;      if (isdark) {         mcurrentcolor = getresources().getcolor(r.color.dark_color);     } else {         mcurrentcolor = getresources().getcolor(r.color.light_color);     }      invalidate(); }

this avoids color assignments in ondraw method. if still unsatisfactory, might try double buffering, mentioned here.

css - Make div keyboard-scrollable in jQuery Mobile? -

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; } ...
