Notification屏蔽下拉菜单具体消息

正常情况下，系统发送一条通知会,在PhoneStatusBar状态栏上会有一个通知的图标，然后在下拉扩展界面会有对应的通知信息。

客户反馈，在使用VoLTE业务的时候，下拉通知栏的VoLTE对应的通知没有具体内容，只有一个VoLTE的图标，这样显示起来很不美观，客户需求要去掉下拉栏的详细通知，保留状态栏上的图标。

跟踪系统notification源码，并没有发现有关于屏蔽下拉状态栏的属性或标记。所以决定自己加一个相关的属性来控制是否显示通知的下拉状态栏。

1. frameworks/base/core/java/android/app/Notification.java

//增加属性/* yueshuai 20151118 modify for hide notification drawer begin *//*** hide notification drawer* @hide*/public static final String EXTRA_AS_HIDE_VIEW = "hideview";/* yueshuai 20151118 modify for hide notification drawer end */

2. packages/services/Telephony/src/com/android/phone/NotificationMgr.java

    /* yueshuai 20151118 modify for hide notification drawer begin */    private static final String HIDE_VIEW = "hideview";    /* yueshuai 20151118 modify for hide notification drawer end */

void updateImsRegistration(boolean registered) {        if (registered) {            Notification notification = new Notification.Builder(mContext)                    .setSmallIcon(R.drawable.ims_state).build();            notification.flags |= Notification.FLAG_ONGOING_EVENT;    /* yueshuai 20151118 modify for hide notification drawer begin */            //加入hideview属性    notification.extras.putString(Notification.EXTRA_AS_HIDE_VIEW,HIDE_VIEW);    /* yueshuai 20151118 modify for hide notification drawer end */            mNotificationManager.notify(                    IMS_REGISTERED_NOTIFICATION,                    notification);        } else {            mNotificationManager.cancel(IMS_REGISTERED_NOTIFICATION);        }    }

3. frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java

 /* yueshuai 20151118 modify for hide notification drawer begin */    private static final String NO_HIDE_VIEW = "nohideview";    private static final String HIDE_VIEW = "hideview";    /* yueshuai 20151118 modify for hide notification drawer end */

 private void updateNotificationShade() {        if (mStackScroller == null) return;……        ArrayList<Entry> activeNotifications = mNotificationData.getActiveNotifications();        ArrayList<ExpandableNotificationRow> toShow = new ArrayList<>(activeNotifications.size());        final int N = activeNotifications.size();        for (int i=0; i<N; i++) {            Entry ent = activeNotifications.get(i);    /* yueshuai 20151118 modify for hide notification drawer begin */             //看是否存在HIDE_VIEW的属性，如果存在则跳过，不需要下拉栏中    if((ent.notification.getNotification().extras.getString(Notification.EXTRA_AS_HIDE_VIEW,NO_HIDE_VIEW)).equals(HIDE_VIEW)){continue;    }/* yueshuai 20151118 modify for hide notification drawer end */            int vis = ent.notification.getNotification().visibility;            // Display public version of the notification if we need to redact.            final boolean hideSensitive =                    !userAllowsPrivateNotificationsInPublic(ent.notification.getUserId());            boolean sensitiveNote = vis == Notification.VISIBILITY_PRIVATE;            boolean sensitivePackage = packageHasVisibilityOverride(ent.notification.getKey());            boolean sensitive = (sensitiveNote && hideSensitive) || sensitivePackage;            boolean showingPublic = sensitive && isLockscreenPublicMode();…… mNotificationPanel.setQsExpansionEnabled(isDeviceProvisioned()                && (mUserSetup || mUserSwitcherController == null                        || !mUserSwitcherController.isSimpleUserSwitcher()));        mShadeUpdates.check();    }
