The getWindow () method cannot use

Question

I created a lockscreen for ics, which will replace the default screen lock. In my code, I want to use a method getWindow()to set "android:hardwareAccelerated"true to increase efficiency.

I have no activity in LockScreen.java . Therefore, I can not use activity.getWindow(). I also tried using context.getWindow()and this.getWindow(). But still he shows an error. How to use a method getWindow()to get a Window object?

LockScreen extends some classes, no? Which one?
