我在OOS Open Beta 15，Android 7.1.1上运行OnePlus 3t。我想让它的警报滑块分别将我的手机放入所有声音/振动/静音模式。在尝试了第三方应用程序和Tasker配置文件的每种可能组合后，我开始研究创建自己的Magisk模块以更改滑块的行为。
我发现所有警报滑块逻辑都在包com.oneplus.threekey内。使用
adb shell 'pm list packages' > C:\packages.txt
我列出了所有已安装的软件包，包含“oneplus”一词的唯一软件包如下：
package:com.oneplus
package:com.oneplus.aod
package:com.oneplus.applocker
package:com.oneplus.calculator
package:com.oneplus.camera
package:com.oneplus.camera.service
package:com.oneplus.config
package:com.oneplus.deskclock
package:com.oneplus.dirac.simplemanager
package:com.oneplus.gallery
package:com.oneplus.iconpack.dives
package:com.oneplus.iconpack.o2default
package:com.oneplus.iconpack.rifon
package:com.oneplus.ifaaservice
package:com.oneplus.opbackup
package:com.oneplus.opbugreport
package:com.oneplus.opbugreportlite
package:com.oneplus.oplocationservice
package:com.oneplus.screenshot
package:com.oneplus.sdcardservice
package:com.oneplus.security
package:com.oneplus.setupwizard
package:com.oneplus.simcontacts
package:com.oneplus.skin
package:com.oneplus.sms.smscplugger
package:com.oneplus.soundrecorder
package:com.oneplus.wallpaper
package:com.oneplus.wifiapsettings
在没有这样的任何地方，我决定进一步研究我的logcat输出。使用“threekey”过滤它，这是我每次更改警报滑块位置时的输出：

在这里我注意到Throwable部分中的三键类/服务（我真的不知道那是什么）调用setZenMode，它似乎负责通知声音。但事实证明Android Developers没有记录setZenMode方法，并且在获取NotificationManager类的实例后无法调用。
在这一点上，我开始没有想法接下来要尝试什么，或者在哪里看。任何帮助让滑块像以前一样工作会很棒！
