語音輸入在android中填充編輯文本？

我正在使用android中的語音輸入。我用的樣品從語音輸入在android中填充編輯文本？

http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html

而且在測試上Xperia X10的，我得到了「現在講」對話框，但我輸入了一些聲音，然後纔會慢慢關閉。我正在嘗試執行語音搜索，例如如果語音輸入是詹姆斯邦德，那麼我想要填寫詹姆斯的名字編輯文本和邦德在姓氏編輯文本。它將在數據庫中搜索名稱。但在嘗試使用API Demo示例時，它不起作用。可能是我錯過了一些東西。任何人都會發布任何聲音輸入樣本，而不是ApiDemos樣本。

在此先感謝。

您可以使用以下代碼進行語音識別。有關語音識別的完整教程，請致電Click Here。
