Comparing the background resources of buttons

Question

button.setBackgroundResource(R.Drawable.abc);
if ( button.getBackground()==getResources().getDrawable(R.drawable.abc))
{
    button.setBackgroundResource(R.drawable.xyz);
}

else if( button.getBackground()==getResources().getDrawable(R.drawable.xyz) )
{
    button.setBackgroundResource(R.drawable.abc);
}

I want to compare the background images set on the button. The above code has been taken from Stack Overflow... but it doesn't seem to work

Please suggest a better method.

Try this

if ( button.getBackground().getConstantState()==getResources().getDrawable(R.drawable.abc).getConstantState())
{
     button.setBackgroundResource(R.drawable.xyz);
}
