Edit you are getting the button freshly like this

Button bb=(Button) findViewById(buttonId);

so it will always remains whoa....because the condition is always false.....

I would suggest you to set Content Description while setting the background resource and then compare the content Description....You can't compare by bb.getBackground()).equals(button.getBackground()) do something like this

 but1=(Button) findViewById(R.id.b1);
    but1.setBackgroundResource(R.drawable.happy);
but1.setContentDescription("happy");

and 

if(bb.getContentDescription().equals(button.getContentDescription())
