Android 添加禁止下拉菜单和实现控制下拉关照栏功能
overlay/vendor/mediatek/proprietary/packages/apps/MtkSettings/res/values-zh-rCN/strings.xml<string name="pull_down_switch">禁用关照下拉菜单</string>
<string name="pull_down_switch2">打开：禁止下拉菜单 \n关闭：答应下拉菜单</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>
【现在添加在显示栏中】
vendor/mediatek/proprietary/packages/apps/MtkSettings/res/xml/display_settings.xml
<!--add disable pull down menu in systemUI-->
<Preference
android:key="statusbar_switch"
android:title="@string/pull_down_switch">
<intent android:action="com.freeme.intent.action.switch"/>
</Preference>
/vendor/mediatek/proprietary/packages/apps/MtkSettings/res/xml/freeme_qs_switch.xml
<?xml version="1.0" encoding="UTF-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<SwitchPreference
android:key="switch_preference"
android:title="@string/pull_down_switch"
android:summary="@string/pull_down_switch2"
android:defaultValue="true"/>
</PreferenceScreen>
/vendor/mediatek/proprietary/packages/apps/MtkSettings/src/com/android/settings/QsSwitchSetting.java
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>

假如是仅实现屏蔽下拉栏【完全不用下拉栏】，就可不用增加菜单开关，这样直接实现return这几个类也可！
