1. 应用通知管理

settings -> apps -> 选择某个应用 -》进入应用信息界面，点击“通知” -> 可以看到该应用的通知，如下图：

dialernotification

图1

该界面对应settings的文件：AppNotificationSettings，其状态的设置项调用NotificationManagerService的相关方法。

        @Override        public void setPackagePriority(String pkg, int uid, int priority) {            checkCallerIsSystem();            mRankingHelper.setPackagePriority(pkg, uid, priority);            savePolicyFile();        }        @Override        public int getPackagePriority(String pkg, int uid) {            checkCallerIsSystem();            return mRankingHelper.getPackagePriority(pkg, uid);        }        @Override        public void setPackagePeekable(String pkg, int uid, boolean peekable) {            checkCallerIsSystem();            mRankingHelper.setPackagePeekable(pkg, uid, peekable);        }        @Override        public boolean getPackagePeekable(String pkg, int uid) {            checkCallerIsSystem();            return mRankingHelper.getPackagePeekable(pkg, uid);        }       。。。。

并且写入到/data/system/notification_policy.xml中进行保存：

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<notification-policy version="1">
<zen version="2" user="0">
<allow calls="true" repeatCallers="false" messages="false" reminders="true" events="true" callsFrom="1" messagesFrom="1" />
<automatic ruleId="2212c7138aaf49c1b997ce90c01c06c4" enabled="false" snoozing="false" name="周一至周五夜间" zen="3" component="android/com.android.server.notification.ScheduleConditionProvider" conditionId="condition://android/schedule?days=1.2.3.4.5&start=22.0&end=7.0" id="condition://android/schedule?days=1.2.3.4.5&start=22.0&end=7.0" summary="..." line1="..." line2="..." icon="0" state="0" flags="2" />

<automatic ruleId="33b5982469fd47b18a92607638a0458e" enabled="false" snoozing="false" name="活动" zen="3" component="android/com.android.server.notification.EventConditionProvider" conditionId="condition://android/event?userId=-10000&calendar=&reply=1" id="condition://android/event?userId=-10000&calendar=&reply=1" summary="..." line1="..." line2="..." icon="0" state="0" flags="2" />
</zen>
<ranking version="1">
<package name="com.baidu.BaiduMap" priority="2" peekable="true" uid="10090" />
<package name="com.qiyi.video" priority="2" peekable="true" uid="10092" />
<package name="com.tencent.qqpimsecure" uid="10100" />
</ranking>
</notification-policy>

图1中的界面也可以通过下拉通知栏长按某个应用的通知，然后点击感叹号图标进入（手机管家）：

长按notification后notification切换到的视图是个viewStub，该viewStub嵌套在布局ExpandableNotificationRow对应的布局status_bar_notification_row中，并且设置setOnInflateListener监听

protected void onFinishInflate() {        super.onFinishInflate();        mPublicLayout = (NotificationContentView) findViewById(R.id.expandedPublic);        mPrivateLayout = (NotificationContentView) findViewById(R.id.expanded);        mGutsStub = (ViewStub) findViewById(R.id.notification_guts_stub);        mGutsStub.setOnInflateListener(new ViewStub.OnInflateListener() {            @Override            public void onInflate(ViewStub stub, View inflated) {                mGuts = (NotificationGuts) inflated;                mGuts.setClipTopAmount(getClipTopAmount());                mGuts.setActualHeight(getActualHeight());                mGutsStub = null;            }        });。。。。。
