如果想修改成一层锁的话，需要修改如下：

 LockPatternKeyguardView.java  中：

private Mode getInitialMode() {

    IccCard.State simState2 = IccCard.State.NOT_READY;

        final IccCard.State simState = mUpdateMonitor.getSimState();

if(FeatureOption.MTK_GEMINI_SUPPORT == true)

{

        simState2 = mUpdateMonitor.getSimStateGemini(Phone.GEMINI_SIM_2);

}

        if (stuckOnLockScreenBecauseSimMissing()) {

            return Mode.LockScreen;

        } else {

            // Show LockScreen first for any screen other than Pattern unlock.

            /*final boolean usingLockPattern = mLockPatternUtils.getKeyguardStoredPasswordQuality()

                    == DevicePolicyManager.PASSWORD_QUALITY_SOMETHING;*/

            final boolean usingPINLock = IsSIMPINRequired();

            Log.i(TAG,"usingLockPattern="+usingPINLock);

            if (isSecure() && usingPINLock) {

                return Mode.UnlockScreen;

            } else {

                return Mode.LockScreen;

            }

        }

    }

 还原成如下：

} else {

            // Show LockScreen first for any screen other than Pattern unlock.

            final boolean usingLockPattern = mLockPatternUtils.getKeyguardStoredPasswordQuality()

                    == DevicePolicyManager.PASSWORD_QUALITY_SOMETHING;

           /* final boolean usingPINLock = IsSIMPINRequired();

            Log.i(TAG,"usingLockPattern="+usingPINLock);*/

            if (isSecure() && usingLockPattern) {

                return Mode.UnlockScreen;

            } else {

                return Mode.LockScreen;

            }
