My problem is how do i get the Background Color? and Compare it with R.color.colorGreen

I have tried some Examples from here but nothing works.

You should see this SO post .

If you're on Android 3.0+ you can get the color value

ColorDrawable buttonColor = (ColorDrawable) button.getBackground(); int color = buttonColor.getColor();

So, your revised if statement would be

ColorDrawable buttonColor = (ColorDrawable) button.getBackground();
int color = buttonColor.getColor();
if (color == getResources().getColor(R.color.colorBlue)) {
    // if statement body
}
