我想使用Kotlin在Android中显示DialogFragment

我想显示DialogFragment clicked按钮时，但我有我的代码中的错误错误是在乐趣“显示”

这个我的代码“点击按钮”

DialogFragment

 val pop = alarm_first() val fm = FragmentManager pop.show( fm , "name") 

而这个我的片段类为“alarm_first”：

 class alarm_first : DialogFragment() { override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View { var myView = inflater!!.inflate(R.layout.fragment_alarm_first , container, false) return myView }} 

Answer 1

编辑这部分

 val pop = alarm_first() val fm = FragmentManager pop.show(fm, "name") 

至

 val pop = alarm_first() val fm = [e-mail] pop.show(fm, "name") 

Answer 2

更换

 val fm = FragmentManager 

同

 val fm = fragmentManager
