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;
}
