android如何实现：当开启图案解锁时，取消滑动解锁

如果想修改成一层锁的话，需要修改如下：

LockPatternKeyguardView.java中：

private ModegetInitialMode() {

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;

}
