android - Change image in imageview onClick -

i want change images in image view on onclick function. have tried this:

bt_audiocapture.setonclicklistener(new view.onclicklistener() {          public void onclick(view view) {              if (checkpermission()) {                  if (bt_audiocapture.getresources().getdrawable(r.drawable.ic_mic).equals(r.drawable.ic_mic)) {                     start();                     bt_audiocapture.setimageresource(r.drawable.ic_stop);                 } else if (bt_audiocapture.getresources().getdrawable(r.drawable.ic_stop).equals(r.drawable.ic_stop)) {                     stop();                     bt_audiocapture.setimageresource(r.drawable.ic_play);                 } else if (bt_audiocapture.getresources().getdrawable(r.drawable.ic_play).equals(r.drawable.ic_play)) {                     play();                 }             }         }     }); 

bt_audiocapture.getresources().getdrawable(r.drawable.ic_mic) returns drawable object. can't compare r.drawable.ic_mic, integer. comparing car green color.

to accomplish task, make field private int state = 0;, , constants

private final state_playing = 1; private final state_stopped = 2; private final state_none = 0; 

and then:

if (state == state_none) {     start();     bt_audiocapture.setimageresource(r.drawable.ic_stop);     state = state_playing; } else if (state == state_playing) {     stop();     bt_audiocapture.setimageresource(r.drawable.ic_play);     state = state_stopped; } else if (state == stopped) {     play();     state = state_playing; }
