文本到語音功能不起作用

儘管我的代碼沒有錯誤且準確，但Android並不會說話。我使用了吐司功能來查看問題發生的位置。但是，這兩個敬酒都被稱爲。文本到語音功能不起作用

我已經刪除了所有不相關的代碼。

下面的代碼大多是相關的。

您正在測試哪個版本的設備？ –

哦，那很重要嗎？我在Galaxy S2上測試過它。 – user3385015

您的代碼有幾個問題。您應該檢查由setLanguage返回的錯誤。在調用onInit之前，您不能撥打speakOut。確保這一點的一種方法是在xml佈局文件中禁用通話按鈕並在onInit中啓用它。

我沒有setLanguage返回的錯誤。 setLanguage有什麼問題？我如何致電onInit？ – user3385015

你不調用onInit，它是一個回調，當你創建TextToSpeech對象時會調用它。在setLanguage put talk.setEnabled（true）之後，只需在佈局xml和onInit中禁用通話按鈕， –
