文字說話導致應用程序崩潰（Android Studio）

Question

我猜這是啓動/構造的錯誤，但參數似乎是正確的，我找不到任何其他問題。這是整個活動代碼。文本到語音的方法和調用它的方法在最底層，oninit方法在創建之後不久。運行時，它不會崩潰，它會激活語音引擎，但不會說話。我把在錯誤部分

Answer 1

com.prometheus.coding.supremisai.Main cannot be cast to android.speech.tts.TextToSpeech$OnInitListener

不論是主需要實現onInitListener控制檯的信息，或者你需要在OnInitListener通過。
