覆盖fun onEditOraction(v：TextView,actionId：Int,event：KeyEvent)

以下是整个代码.这段代码最初是在java中,我使用@L_674_5@ studio将其转换为Kotlin,但现在我收到了这个错误.我尝试重建和清理项目,但这没有用.

val action = supportActionBar //get the actionbar
action!!.setDisplayShowCustomEnabled(true) //enable it to display a custom view in the action bar.
action.setCustomView(R.layout.search_bar)//add the custom view
action.setDisplayShowtitleEnabled(false) //hide the title

edtSearch = action.customView.findViewById(R.id.edtSearch) as EditText //the text editor


//this is a listener to do a search when the user clicks on search button
edtSearch?.setOnEditOractionListener(object : TextView.onEditOractionListener {
    override fun onEditOraction(v: TextView,actionId: Int,event: KeyEvent): Boolean {
    if (actionId == EditorInfo.IME_ACTION_SEARCH) {
         Log.e("TAG","search button pressed")  //doSearch()
         return true
        }
     return false
    }
})
