android - Testing for Resources such as Drawbles and Background -


i need see if there way can test background button has. example, here psueduo code: 

if (button background `r.drawable.black`) {   button.setbackground(to r.drawable.white) }

is there way if statement can done? know how set backgrounds, curious on test portion.

in case, believe tags useful. try this:

//when set button: btn.setbackgroundresource(r.drawable.black); btn.settag(r.drawable.black);   //when re-set button: if(btn.gettag().equals(r.drawable.black)) {     btn.setbackgroundresource(r.drawable.white);     btn.settag(r.drawable.white); }
