how to connect a led bulb with battery and a switch ?

If we're to assume that you're using a normal SPST switch with a battery which can indeed provide enough current and voltage to power the bulb, then it can be hooked up in a normal series circuit or "loop".
Also, (just to make sure I've covered all ground) ask yourself a question: Would you plug this bulb into a wall? If so, then it will not work with batteries. (unless you happen to have an abnormally high voltage battery)

What size battery? What color, specs does the LED have? What kind of switch?
Giving some details will get this question answered as it is a simple answer but impossible to answer without more info.
