2つの同一の文字列はtrueに等しくありません

2つの異なるリストから取得した2つのStringオブジェクトを比較したいのですがequals()、contentEquals()またはを使用しても、==常にfalseです。

最初のリストの文字列がどのように配置されるかと関係がありますか？

編集：それはこの写真のログ結果を不思議に見ています：

                        DictWord.dictWords.forEach {
                            Log.i("testen", "it is: $it and equals 'black'? - ${it.equals("black")}")
                            Log.i("testen", "it is: $it and equals $newWord - ${it.equals(newWord)}")
                            Log.i("testen", "it is: $it and equals $newWord - ${it.contentEquals("black")}")
                            Log.i("testen", "it is: $it and == $newWord - ${it == newWord}")
                            Log.i("black", "it is: 'black' and equals $newWord - ${"black" == newWord}")


...    subStrainsAdapter.addHeaderAndSubmitList(null)
            var textList = mutableListOf<String>()
            var movingText = ""
            thoughtContent.addTextChangedListener(object : TextWatcher {
                override fun afterTextChanged(s: Editable) {}
                override fun beforeTextChanged(
                    s: CharSequence,
                    start: Int, count: Int, after: Int) {}

                    start: Int, before: Int, count: Int)
                {movingText += s.last()}
            })

            //SUBSTRAIN INPUT - goes to onSubStrainEditEnd above when ENTER hit
            thoughtContent.setOnKeyListener(object : View.OnKeyListener {
                @RequiresApi(Build.VERSION_CODES.Q)
                override fun onKey(v: View?, key: Int, event: KeyEvent): Boolean {
                    return if (event.action == KeyEvent.ACTION_DOWN && key == KeyEvent.KEYCODE_SPACE) {
                        textList.add(movingText)
                        movingText = ""
                        false } else false
                }})

上記のコードの出力ログ：
