게시글 삭제시 에러 문의드립니다

FB 규칙 변경 후 에뮬레이터 데이터 지우고 다시 삭제 시도했는데 똑같습니다. 여전히 게시글이 남아있고, 앱도 살아있고, 로그에 뭐 뜨는 것도 없습니다.

작성하신 코드를 공유해주시겠어요?

boardInsideActivity에서 

private lateinit var key : String

여기 lateinit key이라고 만들어놓은것을

private fun showDialog() {

    val mDialogView = LayoutInflater.from(this).inflate(R.layout.custom_dialog, null)

    val mBuilder = AlertDialog.Builder(this)
        .setView(mDialogView)
        .setTitle("게시글 수정/삭제")

    val alertDialog = mBuilder.show()

    alertDialog.findViewById<Button>(R.id.editBtn)?.setOnClickListener {
        Toast.makeText(this, "글이 수정되었습니다", Toast.LENGTH_LONG).show()
        Log.d("LOG Key", key)
    }

    alertDialog.findViewById<Button>(R.id.removeBtn)?.setOnClickListener {

        Log.d("LOG Key", key)

        FBRef.boardRef.child(key).removeValue()
        Toast.makeText(this, "글이 삭제되었습니다", Toast.LENGTH_LONG).show()
        finish()
    }

}

showDialog에서 사용하는데

저 key에 값이 들어가지 않았습니다.

아래 부분을

val key = intent.getStringExtra("key").toString()

이렇게 변경해보세요.

key = intent.getStringExtra("key").toString()

이제 잘 작동하네요 감사합니다!
