我尝试将我的dialogfragment调用到我的loginfragment中，并显示一个警告对话框，show方法显示：
无法使用所提供的参数调用以下任何函数。show（FragmentManager！，String！）定义于org.greenstand.android.TreeTracker.fragments中。CustomDialogFragment show（FragmentTransaction！，String！）定义于org.greenstand.android.TreeTracker.fragments中。CustomDialogFragment

val newFragment = CustomDialogFragment.newInstance("pass content here")

val fm = fragmentManager
newFragment.show(fm, "look")

下面是我的CustomDialogFragment代码：

import android.app.Activity
import android.content.Intent
import android.content.pm.PackageManager
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.Toast

class CustomDialogFragment : DialogFragment()
{
    private var content: String? = null

    override fun onCreate(savedInstanceState: Bundle?)
    {
        super.onCreate(savedInstanceState)
        content = arguments!!.getString("content")

        val style = DialogFragment.STYLE_NO_FRAME
        val theme = R.style.DialogTheme
        setStyle(style, theme)
    }

    override fun onAttach(context: Context) {
        super.onAttach(context)
    }

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup, savedInstanceState: Bundle): View
    {
        val view = inflater!!.inflate(R.layout.layout_dialog, container, false)

        val btnAccept = view.findViewById<View>(R.id.buttonAccept) as Button

        val textViewContent = view.findViewById<View>(R.id.textViewContent) as TextView
        textViewContent.text = content;

        btnAccept.setOnClickListener{
            dismiss();
        }

        return view;
    }

    companion object
    {
        fun newInstance(content: String) : CustomDialogFragment
        {
            val f = CustomDialogFragment()

            val args = Bundle()
            args.putString("content", content)
            f.arguments = args

            return f
        }
    }

}

有没有人能指出我到底需要传递到show方法中的是什么？任何帮助都很感激，谢谢：）
