Android 添加禁止下拉菜单和实现控制下拉通知栏功能

overlay/vendor/mediatek/proprietary/packages/apps/MtkSettings/res/values-zh-rCN/strings.xml

<string name="pull_down_switch">禁用通知下拉菜单</string>
<string name="pull_down_switch2">打开：禁止下拉菜单 \n关闭：准许下拉菜单</string>

overlay/vendor/mediatek/proprietary/packages/apps/MtkSettings/res/values/strings.xml

<add-resource type="string" name="pull_down_switch"/>
<add-resource type="string" name="pull_down_switch2"/>

<string name="pull_down_switch">Disable notify pull-down menu</string>
<string name="pull_down_switch2">ON:disable pull down \nOFF:allow pull down</string>

【目前添加在显示栏中】

开关默认1为打开，功能实现默认为1

反之：

开关默认0为关闭，功能实现默认为0

<这里为默认打开菜单栏开关>
