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：

                                     《notification学习--持续更新中。。。》

                                                               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&amp;start=22.0&amp;end=7.0″ id=”condition://android/schedule?days=1.2.3.4.5&amp;start=22.0&amp;end=7.0″ 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）：

            《notification学习--持续更新中。。。》      《notification学习--持续更新中。。。》

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;
            }
        });
。。。。。
