1.文件位置：

frameworks/base/packages/SystemUI/res/values/config.xml

a.这个文件定义了初始化的一些组件，部分代码如下：

//overlay/frameworks/base/packages/SystemUI/res/values/config.xml

 <!-- The default tiles to display in QuickSettings -->
    <string name="quick_settings_tiles_default" translatable="false">
        wifi,bt,dnd,flashlight,rotation,battery,cell,airplane,cast,screenrecord
    </string>

//以下这几行不更改貌似也可以生效
    <!-- The minimum number of tiles to display in QuickSettings -->
    <integer name="quick_settings_min_num_tiles">6</integer>

    <!-- Tiles native to System UI. Order should match "quick_settings_tiles_default" -->
    <string name="quick_settings_tiles_stock" translatable="false">
        wifi,cell,battery,dnd,flashlight,rotation,bt,airplane,location,hotspot,inversion,saver,dark,work,cast,night,screenrecord,reverse
    </string>

对里面的字符串，进行增加或删除就会去掉相应的快捷图标。

b.还有一些组件是 被设定 了 true 和 false ，用来进行 控制是否让 他们在初始化的时候进行显示。

对于这样的组件你可以自行查找和设置，比如：

<bool name="config_keyguardUserSwitcher">false</bool>

false 修改为 true 就会在下拉菜单显示出 用户账户小图标。

2.下拉菜单屏蔽快捷开关：转储SYSUI堆

diff --git a/frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tileimpl/QSFactoryImpl.java b/frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tileimpl/QSFactoryImpl.java

         }
 

3.下拉菜单屏蔽弹窗：已启用序列控制台
