How to find the screen is locked in android

Question

For my application, I need to know that the screen is locked. How to check this is problematically. I used following flag:

if(WindowManager.LayoutParams.FLAG

Here is what I did:

This handles if the user has unlocked the screen, but not yet entered the home screen or the user's screen is turned off say during a call.

           if (Intent.ACTION_SCREEN_ON.equals(pIntent.getAction()) ||  
                     Intent.ACTION_USER_PRESENT.equals(pIntent.getAction())) {
                if(mListener!=null) {
                    KeyguardManager km = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
                    boolean locked = km.inKeyguardRestrictedInputMode();
                    Log.v(TAG, ": Phone lock state from KEYGUARD_SERVICE: Current state:" + (locked ? "LOCKED":"UNLOCKED"));
                    mIsPhoneLocked = locked;
                }
            }
