我正在用AWT框架創建一個基本的語音識別Java API。 我完成了我的編碼,我的API也正在運行,但現在我想在識別正在進行時在我的API中引入「停止」按鈕。 我正在嘗試在語音識別開始後使此Stop按鈕有效。 但我無法這樣做。 我想打破停止按鈕點擊識別的while循環,而不是讓while循環無限。 請幫我出您的建議.. 我的主類是:在java語音識別sphinx循環中啓用按鈕啓用按鈕API

您可以創建在您的主一個public static boolean isStart;和引用它爲您while循環。

因此,而不是使用while(true)你可以使用類似while(main.isStart)。 然後只需設置isStart = false;當停止按鈕是按下,並設置isStart = true;然後當開始按鈕是按下。

您應該始終避免在您的代碼中使用while(true),這很可能是更好的方法。

感謝您的回覆。 但實際上問題是,只要我點擊「說話」按鈕,我的API UI就會被掛起。我無法按下任何按鈕,任何按鈕都不會響應,除非我從此while循環出來。 – user3703157

如果您的UI在說話過程中停止,您可能希望讓它在單獨的線程上運行並異步運行。查看使用異步任務的http://developer.android.com/reference/android/os/AsyncTask.html。 –
