uniapp-x 官方文档 UTSActivityCallback 示例有误

大标题

官方链接 :https://doc.dcloud.net.cn/uni-app-x/uts/utsactivitycallback.html#UniActivityKeyEventCallback

uvue代码部分缺少变量 cbText，新建 uni_modules插件不能以uts开头，即示例中的 uts-syntaxcase 不可以以这个命名，将其改为 muts-syntaxcase

uts代码代码缺少所有需要引入的库，除了内置库。

缺少以下库

import Bundle from "android.os.Bundle"  
import KeyEvent from "android.view.KeyEvent"  
import WindowManager from "android.view.WindowManager"   
import Menu from "android.view.Menu"  
import ActionMode from "android.view.ActionMode"  
import Configuration from "android.content.res.Configuration"  
import KeyboardShortcutGroup from "android.view.KeyboardShortcutGroup";
