1、禁止systemUI下拉状态栏和通知栏的核心代码部分
framework/base/packages/apps/SystemUI/src/com/android/systemui/keyguard/KeyguardViewMediator.java
framework/base/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/CollapsedStatusBarFragment.java

/framework/base/packages/apps/SystemUI/src/com/android/systemui/statusbar/notification/NotificationStackScrollLayout.java
2、禁止systemUI下拉状态栏和通知栏，考虑需要在锁屏状态下，和未锁屏状态下
2.1 没有锁屏状态下通过
KeyguardViewMediator.java来在adjustStatusBarLocked(）中通过设置StatusBarManager的flag
属性来设置禁用下拉状态栏，然后在开机以后就禁用下拉状态栏达到禁用的目的
framework/base/packages/apps/SystemUI/src/com/android/systemui/keyguard/KeyguardViewMediator.java
private void handleShow(Bundle options) {
Trace.beginSection("KeyguardViewMediator#handleShow");
final int currentUser = KeyguardUpdateMonitor.getCurrentUser();
if (mLockPatternUtils.isSecure(currentUser)) {
mLockPatternUtils.getDevicePolicyManager().reportKeyguardSecured(currentUser);
}
synchronized (KeyguardViewMediator.this) {
if (!mSystemReady) {
if (DEBUG) Log.d(TAG, "ignoring handleShow because system is not ready.");
return;
} else {
if (DEBUG) Log.d(TAG, "handleShow");
}
mHiding = false;
mWakeAndUnlocking = false;
setShowingLocked(true);
mKeyguardViewControllerLazy.get().show(options);
resetKeyguardDonePendingLocked();
mHideAnimationRun = false;
adjustStatusBarLocked();
userActivity();
mUpdateMonitor.setKeyguardGoingAway(false);
mKeyguardViewControllerLazy.get().setKeyguardGoingAwayState(false);
mShowKeyguardWakeLock.release();
}
private void adjustStatusBarLocked(boolean forceHideHomeRecentsButtons,
boolean forceClearFlags) {
if (mStatusBarManager == null) {
mStatusBarManager = (StatusBarManager)
mContext.getSystemService(Context.STATUS_BAR_SERVICE);
}
if (mStatusBarManager == null) {
Log.w(TAG, "Could not get status bar manager");
} else {
// Disable aspects of the system/status/navigation bars that must not be re-enabled by
// windows that appear on top, ever
int flags = StatusBarManager.DISABLE_NONE;
// TODO (b/155663717) After restart, status bar will not properly hide home button
// unless disable is called to show un-hide it once first
if (forceClearFlags) {
mStatusBarManager.disable(flags);
}
if (forceHideHomeRecentsButtons || isShowingAndNotOccluded()) {
if (!mShowHomeOverLockscreen || !mInGestureNavigationMode) {
flags |= StatusBarManager.DISABLE_HOME;
}
flags |= StatusBarManager.DISABLE_RECENT;
}
if (DEBUG) {
Log.d(TAG, "adjustStatusBarLocked: mShowing=" + mShowing + " mOccluded=" + mOccluded
+ " isSecure=" + isSecure() + " force=" + forceHideHomeRecentsButtons
+ " --> flags=0x" + Integer.toHexString(flags));
}
mStatusBarManager.disable(flags);
}
}
在调用show 显示状态栏的时候，adjustStatusBarLocked() 可以设置 mStatusBarManager 的flag为StatusBarManager.DISABLE_EXPAND表示禁用下拉状态栏

2.2 StatusBar 中不显示通知信息的图片:
在锁屏通知栏中去掉显示通知的部分，达到禁用下拉状态栏的功能
