i trying set orange color in background of ok button.but size got changed. tried use following code :

btnok.getbackground().setcolorfilter(getresources().getcolor(r.color.orange_color)), porterduff.mode.src_atop); 

it giving me error :setcolorfilter() in drawable can not applied (int) . please me fix issue

if want change background color retain other styles, below might help.

btnok.getbackground().setcolorfilter(contextcompat.getcolor(this, r.color.coloraccent), porterduff.mode.multiply);
