android - ImageView setImageResource not working -

i have custom class inherits relativelayout. have imagebutton called control_btn that's defined , added layout in init() method. on ondraw, have following code (among other things):

    control_btn.setimageresource(r.drawable.play_new);     control_btn.getlayoutparams().width = getpixels(20);     control_btn.getlayoutparams().height = getpixels(20);     control_btn.setx(getpixels(0));     control_btn.sety(getpixels(10));     control_btn.setscaletype(imageview.scaletype.center_inside);     control_btn.setadjustviewbounds(true);     control_btn.setpadding(0, 0, 0, 0);     control_btn.setbackgroundcolor(color.transparent);     control_btn.setonclicklistener(new onclicklistener() {         @override         public void onclick(view v) {             control_btn.setimageresource(r.drawable.pause);             log.d("wth", "clicked");         }     }); 

however, image never changes, despite getting log entry. further, have imagebutton same code image change (also inside custom class).

any ideas on how fix this?

put setimageresource init() method, problem fixed.
