如何添加一个数字键盘

在相应的fragment下添加一下相应的变量

lateinit var periodDialog: PeriodDialog

lateinit var multipleDialog: PeriodDialog

写两个初始化方法 应该是对两个变量的赋值

    }

在页面的onActivityCreated方法下
super.onActivityCreated(savedInstanceState)
viewModel = ViewModelProvider(this).get(SuperLottoBetViewModel::class.java)
这个之后调用两个初始化方法
initMultipleDialog()
initPeriodDialog()

暂时ViewMode用的和别人共享的那一套

触发方法
//多期按钮
binding.periodTextView.setOnClickListener{
periodDialog.show()
}//多倍按钮
binding.multipleTextView.setOnClickListener{
multipleDialog.show()
}**
