android開啟圖案解鎖時，取消滑動解鎖

 　　如果想修改成一層鎖的話，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;

　　}

　　}

　　}

　　還原成如下：

　　} 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;

　　}
