How to switch between two imageview in OnclickListner

I have an ImageView and i want to switch between two images in Onclick Listner For more details: in shared prefernce i have checkbox to enable and desable sound and in a layout i have an image view to handle sound in shared prefernce . this is my code :

 imgsound=  (ImageView)findViewById(R.id.imgsound);
    imgsound.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {
           if(Settings.isSoundEnabled(getApplicationContext())){
               imgsound.setImageResource(ic_sound_off);
               setSoundFalse(getApplicationContext());
           }
           if(Settings.isSounddesabled(getApplicationContext())){
               imgsound.setImageResource(ic_sound_on);
               setSoundTrue(getApplicationContext());
           }
       }
   });

the First (if-statement) work well and the image turn to ic_sound_off and sound desabled , but when i click again to enable sound and turn image to ic_sound_on dosn't work
