Set Rotation throughout application

Is there a way to set the application's orientation (not just in one activity) programatically开发者_StackOverflow?

---

write every activity onCreate() method

//---change to landscape mode---
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

//---change to portrait mode---
         setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

may be work..
